Healthy Work-Life Balance For Teachers
Healthy Work-Life Balance For Teachers Advisory board member, Jeanne, describes why it is important to unplug once and a while to avoid burnout. This way you will be able to teach better and live happier. by Jeanne Wolz Unlike many other jobs, the time you can spend on teaching is limitless, and the impact feels immense. This can be a dangerous recipe for passionate teachers--particularly if those passionate people do not consciously enforce boundaries. Boundaries are what protect your incredible energy, creativity, and passion. They affirm that no oneâs energy is infinite. They are a form of self-respect, self-care, and serve as a model for our students who watch how we operate in this busy world. Here are a few common areas that teachers can strengthen their own boundaries and in turn, teach better and live happier: 1. Turn off any and all work notifications from your phone. Every reminder of work responsibilities that we receive while weâre off the clock extends that work day a little longer and our anxiety levels a little higher. All of those âdingsâ can add up. This week, try an experiment. Turn off notifications for one work-related app on your phone -- whether it be your work email, a parent-messaging app, or any other application that brings your mind back to school. Turn it off for a week, and observe two things: How you feel. How your work was affected. When I started shutting off notifications from work on my phone, I felt extraordinary freedom. I turned off notifications one a time, starting with student notifications from Google Classroom and ending with notifications of work email. Turning off my email notifications from work was the most incredible one of all. I learned that there was never an emergency that couldnât wait to be handled until the next morning--and I also learned, as I grew my boundaries, that there was never a school emergency I should handle until the next morning. On top of that, my concentration levels increased both at home and at work. Give it a go and see what might work better for you. 2. Put your phone away when youâre most vulnerable. Many of us have an entire professional world inside of our phones. Even if weâre not receiving notifications, there is still the temptation to log into email, or scroll through other teacherâs social media feeds, or read news that drains us. There is a time and place for all of these things, but when we make it easy to access them when weâre the most tired, drained, or stressed, our phone can turn into distraction from serving our actual needs and adding deeper joy to our lives. If youâre interested in learning more about decreasing screen dependence, there is an incredible Masterclass through the Mindfulness app, Calm, about managing screen addiction. While you have to subscribe, the Premium version of the app is free for educators. Well worth the listen, the Masterclass gives pointers on how to detach yourself from the phone-checking habit and focus more deeply on cultivating mindfulness and joy in your life. One of the best pointers I learned from the class was to put my phone out of the room when Iâm the most vulnerable to checking it. This, for me, are the times Iâm tired (beginning/end of day and before bed) and hungry (before meals). Just by keeping my phone outside of the bedroom, I was able to give myself 2-3 additional hours of more replenishing activities like reading, sleeping, or simply listening to the silence (#teacherzen). Small steps like this can make a huge difference in setting stronger boundaries to enhance your personal life and keep work at work. 3. Have set times when work is off-limits. Just like putting your phone out of the room youâre in, keeping work sectioned to specific hours of the day can go a long way in providing breathing and replenishing space. To decide which hours of the day should be designated as âno-workâ hours, pay attention for a few days which times of the day you feel the least productive. For me, this was after dinner. I noticed that no matter how hard I tried or how much I felt I needed to get done, I couldnât get myself to be even remotely as productive as I was during plan periods or before school. So that was my first cut: no work after dinner. Eventually, this grew to no work on Saturdays, and no more than 2 hours of work on Sundays. The transformation was incredible. With these boundaries, I found myself saying yes to so much more - board games in the middle of the week, going out to dinner on Sunday nights, trivia with friends on Wednesday. As my boundaries became firmer, my personal life bloomed. Another interesting result? My productivity increased. So, your next challenge this week is to identify what hours of the day are particularly sluggish for you. Next week, do something else during those hours instead of work. Observe what happens. 4. Add something not work-related to your life. As you chip away your work hours and distractions during the day, youâre going to find that you have more time and energy than before. For many, this vacuum can be the downfall to keeping your work-life balance habits. If youâre one of those people that always feel like you need to be doing something (see my hand raised?), youâre going to feel this time/energy vacuum big-time. Thatâs where some thinking ahead comes in. Get ahead of yourself and find something new to commit to in your personal life. This could be as simple as playing a game with your kids at night, having weekly drinks with non-work friends, starting a new workout routine, or even joining a art class. The possibilities are endless. As teachers, we can feel the pressure to isolate our personal lives to our breaks -- âIâll take that art class maybe over the summer.â Or âIâll have time to games with my kids over the weekend.â Every time we defer these little nuggets of happiness, we drain our energy and our passion. Happiness is not meant to be compartmentalized, and your energy is not infinite. Youâre allowed to be happy all year long, and to make that happen, itâs going to take a little boundary-making on your part. Teachers need balance just like everybody else. And while the system may make it feel difficult to achieve it, that doesnât mean itâs not worth fighting for. Itâs worth beyond just improving our teaching, itâs worth it because we deserve to be happy. For more on self-care, check out these resources: Calm - free for educators!

Philisophical Background of The Stranger Essay - 1436 Words
Camusââ¬â¢ The Stranger Its Philosophical Background Albert Camusââ¬â¢ novel, The Stranger, appealed to a younger European generation that was trying to find its view of life after the tragedies of WWII and Nazism. Though he eventually came to more mature notions of how a human being should act before his tragic death from a accident in 1960, Camus always believed in the ideas expressed in The Stranger that man must find his own meaning in life, separate from religious or political doctrine. While he was brought up a Catholic, he largely rejected religious authority and he opposed any rigid political authority because of his experiences with totalitarianism. Marxism and Communism were popular political ideas in France at the time, but Camusâ⬠¦show more contentâ⬠¦Existentialism emphasized the freedoms that humans have and the need to exercise their individual human will in responsible ways. His philosophy tended to be atheistic and Camus himself rejected all religion. The existentialists borrowed many of their basic ideas fr om the 19th century German Nietzsche, although there also were Christian types of existentialism derived from the work of Kierkegaard. Existentialism reacted against more standard philosophies such as rationalism and empiricism that looked to find some order in the universe and in human affairs. The atheist Mersaultââ¬â¢s denial of any rational meaning to his life represents this idea in fictionalized form Camusââ¬â¢ philosophy seems to have come out of his personal experience. He grew up poor in Algeria but seemed to recognize from a young age that even the poor could appreciate the beauty of nature. It has been noted, according to the Encyclopedia Britannica that his early essays were ââ¬Å"intensely lyrical meditations on the Algerian countryside. He valued natural beauty as something even poor people like himself could enjoy.â⬠His early writings also ââ¬Å"contrast the fragile mortality of human beings with the enduring nature of the physical world.â⬠Camusâ⠬⢠interest in the physical world, as opposed to social life or emotions, is well displayed in The Stranger. In the novel, Mersault is interested in reactions of his own body, his sexual

Why Did Alexander the Great Burn Persepolis
In May 330 B.C., a little over a month before Alexander the Great went after the escaped, last, Great King of the Achaemenid Persians (Darius III), he burned the kings palaces at Persepolis for reasons we will never know for sure. Especially since Alexander later regretted it, scholars and others have puzzled over what motivated such vandalism. The reasons suggested generally boil down to intoxication, policy, or revenge (perversity) [Borza]. Alexander needed to pay his men, so he had allowed them to pillage the ceremonial capital city of Persepolis, once the Iranian nobles opened their gates to the Macedonian king. The first century B.C. Greek historian Diodorus Siculus says Alexander took an amount estimated to be almost 3500 tons of precious metals from the palace buildings, carried away on innumerable pack animals, perhaps to Susa (future site of the mass marriage of Macedonians, like Hephaestion, to Iranian women, in 324). 71 1 Alexander ascended to the citadel terrace and took possession of the treasure there. This had been accumulated from the state revenues, beginning with Cyrus, the first king of the Persians, down to that time, and the vaults were packed full of silver and gold. 2 The total was found to be one hundred and twenty thousand talents, when the gold was estimated in terms of silver. Alexander wanted to take some money with him to meet the costs of the war, and to deposit the rest in Susa and keep it under guard in that city. Accordingly he sent for a vast number of mules from Babylon and Mesopotamia, as well as from Susa itself, both pack and harness animals as well as three thousand pack camels.ââ¬âDiodorus Siculus Nor was the money found here less, he says, than at Susa, besides other movables and treasure, as much as ten thousand pair of mules and five thousand camels could well carry away.ââ¬âPlutarch, Life of Alexander Persepolis was now Alexanders property.à Who Told Alexander to Burn Persepolis? The Greek-writing Roman historian Arrian (c. A.D. 87 - after 145) says Alexanders trusty Macedonian general Parmenion urged Alexander not to burn it, but Alexander did so, anyway. Alexander claimed he was doing it as an act of revenge for the desecration of the Acropolis in Athens during the Persian War. The Persians had burned and razed the gods temples on the Acropolis and other Athenian Greek property between the time they massacred the Spartans and company at Thermopylae and their naval defeat at Salamis, where almost all the residents of Athens had fled. Arrian: 3.18.11-12 He also set the Persian palace on fire against the advice of Parmenion, who argued that it was ignoble to destroy what was now his own property and that the peoples of Asia would not pay heed to him in the same way if they assumed he had no intention of governing Asia but would merely conquer and move on. [12]But Alexander declared that he wanted to pay back the Persians, who, when they invaded Greece, had razed Athens and burned the temples, and to exact retribution for all the other wrongs they had committed against the Greeks. It seems to me, however, that in doing this Alexander was not acting sensibly, nor do I think there could be any punishment for Persians of a bygone era.ââ¬âPamela Mensch, edited by James Romm Other writers, including Plutarch, Quintus Curtius (1st century A.D.), and Diodorus Siculus say that at a drunken banquet, the courtesan Thais (thought to have been a mistress of Ptolemy) urged the Greeks to take this revenge, which was then accomplished by a tippling procession of arsonists. 72 1 Alexander held games in honour of his victories. He performed costly sacrifices to the gods and entertained his friends bountifully. While they were feasting and the drinking was far advanced, as they began to be drunken a madness took possession of the minds of the intoxicated guests. 2 At this point one of the women present, Thais by name and Attic by origin, said that for Alexander it would be the finest of all his feats in Asia if he joined them in a triumphal procession, set fire to the palaces, and permitted womens hands in a minute to extinguish the famed accomplishments of the Persians. 3 This was said to men who were still young and giddy with wine, and so, as would be expected, someone shouted out to form the comus and to light torches, and urged all to take vengeance for the destruction of the Greek temples. 4 Others took up the cry and said that this was a deed worthy of Alexander alone. When the king had caught fire at their words, all leaped up from their couches a nd passed the word along to form a victory procession in honour of Dionysius.5 Promptly many torches were gathered. Female musicians were present at the banquet, so the king led them all out for the comus to the sound of voices and flutes and pipes, Thais the courtesan leading the whole performance. 6 She was the first, after the king, to hurl her blazing torch into the palace. ââ¬âDiodorus Siculus XVII.72 It may be that the courtesans speech was planned, the act premeditated. Scholars have sought clear motives. Perhaps Alexander agreed to or ordered the burning to send a signal to the Iranians that they must submit to him. The destruction would also send the message that Alexander was not simply a replacement for the last Achaemenid Persian king (who had not yet, but would soon be assassinated by his cousin Bessus before Alexander could reach him), but instead a foreign conqueror.à Sources Fire from Heaven: Alexander at Persepolis, by Eugene N.

Technology and Reading free essay sample
We Read Reading has gone from print to becoming digital in todays world and affects not only the way we read but also the way we communicate with one another. since we are conscience about technology altering the way we read. Remember what a book looks like? Let me show you that by leaving our prints behind, the way we read today has scaled toa digital level, leaving standard books and letters obsolete. Even though you cant furnish a room with Just a single device, Ilke you are able with books, or you cant necessarily fling your e-reader across the room because you risk breaking it. Despite Jabr (April, 2013) stating Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. , technology has changed the way we communicate with the means of social media, the way we conduct business, and the way we plan for our future by Improving technology even further. The use ot social media has in tact attected us as a society in the way we read now. Facebook has been the most productive social network that has implemented the news and apps together seamlessly. The news has never been easier to be shared mong the world since the popularity of Facebook has developed. News agencies have had the opportunity to create their business pages via Facebook and spread the pages out globally to the active users on this social network giant. News articles are now viewable online and can be shared by a status update through Facebook, along with videos, poll questions, and even customer Input through direct messages or comments on these status updates. The news agency can find out precisely what readers are saying about their content and In most cases the help of their audience sharing the content or article on their own news feed has increased views. MacManus (2011) has said, Media companies such as Washington Post and The Guardian have connected to Facebook so tightly that even the mere fact of clicking on a link to their site sends an update to your Facebook news feed. If this is true, then the Integration of our dally Interests In these pages online and the technology with social media is stronger than ever. Can you imagine what will happen in the next 5, 10, or even 20 years? On the side of social media you have another network in Twitter, which allows people to connect by sharing their thoughts or links within a 160 haracter limit. Twitter has also changed the way we read because of its to the point updates. People now have a shorter attention span than ever with Twitters character limit, the patience people once had has diminished when reading news articles and stories, now all they want Is a summary. Ultimately this can affect an author or Journalist by having to, without a choice, blow people away with their articles or novels. Only time will tell if that will lead to a good or bad thing. Visual representation has been influenced by reading as well, with the likes of Vine videos here the videos are compacted into six seconds. Now when people view longer videos, tney lose patlence, It could De posslDle Decause 0T tne popularlty 0T tne slte for now, and hopefully it will fade away and get back to normal. I doubt it will since naturally, times have changed and have the pace at which we live has increased as each decade passes. These changes in technology have had a positive effect in the way our businesses operate today. Technology has changed the way the world conducts business in the world today. One of the major changes in business has been to conduct business with the use of -mail. E-mail in the business world has had a strong impact because now you can market your business with e-mail with E-mail Marketing much like mailing out flyers however sending out an e-mail is much more cost efficient and happens almost instantly. Speaking of cost efficiency, you can now do business across the world without having to send a hand-written or typed up letter to be mailed out and wait for a response to be mailed all the way back. You can also send out company wide information out to all of your employees to keep them up-to-date with how business is going. According to Kleiman (Forbes, 2013) theres still something to be said for taking the time to hand-write your thoughts. This ultimately means that it is a more formal way of conducting business, it also means you took the time to hand write the letter instead of sending an e-mail, which is said to be informal. Technology has had its impact on advertising as well, when you compare advertisements on print and online. Cost efficiency in advertising online rather than print is tremendously improved, where you can pay for the amount of clicks or hits you get only you are aying for what people already see rather than printing advertisements and risking people not seeing your ad. Statistic track-ability is also a huge plus when you advertise online, an issue you would have if you were to print your advertisements. Everything that has been outlined so far leaves one big question: What does the future have in store for technology and the way we read? The future of technology will affect the way we read and the way we operate knowing how others will read and communicate with us. The applications and devices that already exist for replacing books are expanding such as the Kindle line of products. Kindle is leading the way in innovation, with their newest product, the Kindle Single is where you read an essay or short story rather than a full length novel all published in digital form rather than printed on a book. Now another application is the Type N Walk app where it allows a user to send a text message from their smartphone and be able to see what is in front of them by way of the camera on the smartphone becoming activated. A society where we are constantly on our phones, this is what it has come to. How far will these new innovations go? Maybe biology will be the next big thing. There may come a time where books and devices no longer exist, with everything getting programmed into our minds. There really is no farfetched idea too extreme since technology moves rapidly through the times. The future is here now and it is not crazy to think that one day soon, we will have the ability to Just scan through a database Just by thinking it or speaking it for the convenience and rapid pace that time is going at. We will eventually have everything we search on the internet tapped into our brains for a more efficient society. Our brains can be connected to a glooal network so tnat companles wlll nen Know wnat we Ilke individually, with our privacy being taken away along with it.

Mississippi Burning Essays - Films, Mississippi Burning,
Mississippi Burning Mississippi Burning is a truly well-crafted movie about three civil rights workers, two of them white and the third black, who were murdered in Jessup County, Mississippi in 1964. This happens in the middle of the civil rights movement. Mississippi Burning is a rivetting drama based on a shocking true story. I feel Mississippi Burning is a great movie displaying the hateful ways of the south in the sixety's. The movie starts out with the three civil rights workers driving through Jessup County. They noticed that they were being followed by two cars. One of the mysterious cars started to ram the workers' vehicle, and they then desperately attempted to escape their attackers. When it seemed they had lost their assailants, the driver noticed a siren and lights. He pulled over only to be greeted by racial slurs and an eventual bullet to the head. All three workers were executed. Mr. Ward and Mr. Anderson are the two F.B.I. agents called up for the missing people case. They enter the town and ask around if anyone knows anything about the workers. When confronting the Sheriff and deputies, Ward and Anderson are greeted with hostility and sarcasm from the Sheriff's Deputy, Clinton Pell. When they question the Sheriff, Roy Stukey, he trivializes the case, proclaiming that the three workers were probably in Chicago, laughing at all the fuss they made. Ward and Anderson clash throughout the movie, they both have different ideas on what to focus on. Ward is in his late twenty's, and has been assigned supervisor of the case. He goes by the book and likes to follow proper procedure. Anderson is in his early 50's and from the south. He likes to get information any way possible. Anderson feels some resentment to Ward because he wasn't put head of the case. Ward and Anderson started to interview the black townsfolk about who killed the three boys, the violence escalated. Black churches were burned down and barns were set afire. Some of the blacks who said anything were beaten. One boy was locked in a chicken cook in the middle of a cotton field. Most of the black people refused to say anything, but the ones who did blamed the corrupt Sheriff's Department. Ward decides to call for more men. After enough asking around, the F.B.I. agents discover that the civil rights workers' car in a swamp, half-way submerged. Ward calls for one hundred more men to help comb through the area and for support on the case. This greatly outrages the Sheriff's Department, the Mayor, and many of the townspeople. It even brings country wide media coverage on the case. Throughout all of this, even more burnings occur, and the crimes become even more heinous. Ward and Anderson do some checking on the sheriff's and his deputies, and discover that Clinton Pell is one of the leaders of a local Klan branch. They question him, but he denies everything. The violence level is at an all time high. Lynching even occurs. Eventually, the bodies of the three civil rights workers are found in the swamp. The whole ordeal heats up quickly, with more evidence mounting up against the Sheriff's Department. Ward lets Anderson start to do more things his way, and starts to ruthlessly intimidate his suspects. They know that it would be impossible to convict any of the suspects in a state court, so they go after them for civil rights violations. After detaining one of the men, Lester Cowens, they scare him into giving them seven names. Two of them Sheriff Stuckey and Deputy Clinton Pell. Cowens says that Stukey and another man, Clayton Townley, another KKK leader, planned the murders but were not actually at the scene of the crime. Six out of the seven were convicted of civil rights violations. The sentencing went as follows. Frank Bailey (a bartender, trigger man): Ten years in federal prison. Lester Cowens: Three years in federal prison. Floyed Swiley: Seven years in federal prison. Clinton Pell: Ten years in federal prison. Sheriff Ray Stuckey: Acquitted of all charges. Wesley Cooke: Seven years in federal prison. Clayton Townley: Ten years in federal prison. Mississippi Burning had great visuals. It wasn't so much the special effects, but just the way it presented itself. The

Joints and Body Movements Essay Example
Joints and Body Movements Essay Example Joints and Body Movements Paper Joints and Body Movements Paper Purpose: What is the purpose of this exercise? In this exercise I will exam how joints function and thereby discover how they allow for movement in the body. Joints are where two bones come together. The joints hold the bones together and allow for movement of the skeleton. All of the bones, except the hyoid bone in the neck, form a joint. Joints are often categorized by the amount of motion they allow. Some of the joints are fixed, like those in the skull, allow for no movement. Other joints, like those between the vertebrae of the spine, allow for some movement. Most of the joints are free moving synovial joints. In this exercise I will exam how joints function and thereby discover how they allow for movement in the body. Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. Basic lab precautions, including keep a clean workspace and washing your hand when dealing with raw poultry. In order to ensure that this occurs layout the equipment beforehand in a clean sterile environment and follow safe work practices. Exercise 1: Questions A. As you observe the skull, explain how the structure of the sutures between the cranial bones is related to the overall function of the cranium. Childrenââ¬â¢s heads needs to squeeze through the birth canal during delivery, humans during infancy have evolved with a soft skull composed of many different bony plates that meet at regions called cranial sutures. These sutures also allow the skull to grow rapidly during the first year of life, at which time the bones start to slowly fuse together. This allows the skull to continue to protect the skull during early development. B. Why are synarthroses an important component of fibrous joints? These joints are weight bearing and the joints provide stability and cushioning. Synarthrotic joint is to provide a stable union between bony surfaces. The suture and synchondrosis actually become more stable when ossification of the joint takes place. Exercise 2: Questions A. Cartilaginous joints exhibit amphiarthroses. Why is this important? Amphiarthroses provides an articulation between bony surfaces that permits limited motion and is connected by ligaments or elastic cartilage, such as that between the vertebrae. B. Structurally, how are cartilaginous joints similar? Cartilaginous joints are connected entirely by cartilage. Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. Cartilaginous joints also form the growth regions of immature long bones and the intervertebral discs of the spinal column. Exercise 3: Questions A. Which type of synovial joint has the least amount of movement? Plane joints permit sliding or gliding movements in the plane of articular surfaces. The opposed surfaces of the bones are flat or almost fat, with movement limited by their tight joint capsules. B. Why are diarthroses important for synovial joints? Diarthrosis permits a variety of movements. All diarthrosis joints are synovial joints and the terms diarthrosis and synovial joint are considered equivalent. C. Which synovial joint is most movable? A ball and socket joint is a joint in which the distal bone is capable of motion around an indefinite number of axes, which have one common center. It enables the bone to move in a 360à ° angle. D. What are the four structural characteristics that all synovial joints share? Synovial joints all have synovial fluid, articular cartilage, articular capsule, synovial membrane, capsular ligaments, blood vessels, and sensory nerves. Exercise 4: Questions A. Which of the body movements was the most difficult to perform? Why? Inversion which is a gliding joint and provides little movement. B. Hinge joints like the elbow and knee have limited movement. Why are these types of joints more prone to injury? Hinge joints in the elbow and knee contain a lot of anatomical structures packed into a tiny space and when challenged with heavy and constant use, it thus especially prone to injury and infection. C. When performing flexion on the arm, the biceps muscle (on the anterior of the arm) contracts. What happens to the triceps muscle (on the posterior of the arm) as this action is performed? As you perform flexion on your arm the triceps muscle relaxes. D. Both the shoulder and the hip are ball and socket joints. Why does the shoulder have a greater range of motion than the hip? The muscles and joints of the shoulder allow it to move through a remarkable range of motion, making it the most mobile joint in the human body. The shoulder can abduct, adduct rotate, be raised in front of and behind the torso and move through a full 360à ° in the sagittal plane. Exercise 5: Observations Sketch your chicken wing: Label the bones, muscles, tendons and joints. Exercise 5: Questions A. What effect will the tearing of a tendon have on its corresponding muscle? The corresponding muscle will shrink due to the decreased activity tendon. This is because when the tendon is torn the area around the tendon will not be in very much use until the tendon is repaired which can take a good while unless professionally handled. The muscle will go back to its original size once the tendon heals and the muscle is used more. B. Why are ligaments harder to heal than tendons? Tendons heal faster than ligaments. The reason is that tendons are connected to the muscle, which will allow them to receive a larger blood flow. Ligaments are connected to bone which supplies less blood. Blood is the key -what carries nutrients in order to repair the tissue. C. Compare and contrast tendons and ligaments. Ligaments connect bone to bone and tendons connect bone to muscle. D. What is the function of fascia? It is responsible for maintaining structural, provides support and protection, and acts as a shock absorber. The function of muscle fasciae is to reduce friction to minimize the reduction of muscular force. Fasciae: a) Provide a sliding and gliding environment for muscles. b)Suspend organs in their proper place. c) Transmit movement from muscles to bones, and d) Provide a supportive and movable wrapping for nerves and blood vessels as they pass through and between muscles. [ E. What effect would the loss of articular cartilage have on a joint, its bones and their corresponding muscles? It causes the breakdown of the cartilage in joints. It also called degenerative arthritis. Cartilage is the joints cushion. It covers the ends of bones and allows free movement. If it becomes rough, frays, or wears away, bones grind against each other. As a result, the joint becomes irritated and inflamed. Sometimes the irritation causes abnormal bone growths, called spurs, which increase swelling. Conclusions Explain how skin, bones, and muscles are related to each other. Why is this relationship important to the understanding of the skeletal and muscular systems? Joints are where two bones come together. The joints hold the bones together and allow for movement of the skeleton. All of the bones, except the hyoid bone in the neck, form a joint. Joints are often categorized by the amount of motion they allow. Some of the joints are fixed, like those in the skull, allow for no movement. Other joints, like those between the vertebrae of the spine, allow for some movement. Most of the joints are free moving synovial joints.
