What is the synovial joint?
Synovial joint is the most movable and most widespread type of joint throughout the body. Sometimes it is referred to as the course. The term "synovial" concerns the tissue involved in the joint and "diarsé" refers to the allowed movement. Some examples of synovial joints are those found in wrists, elbows, hips and knees.
"Synovial" is derived from the Latin word for eggs. The name was given because of the egg white appearance of the synovial fluid and the nutritional effect it has on the joint. Synovial joints differ from fibrous or cartilage joints that do not include joint cavities and are less mobile. The cavity and membrane spread outward from the articular cartilage. The synovial membrane excludes synovial fluid, which provides lubrication for a highly mobile joint. Synovial joints may include more bonds than typical of other joints, helping to stabilize the joint despite its diverse movement. Like other joints, synovial joints host a large nervous net.
Synovial joint can be one of several different types, including plane joints, curtain, pivot, condyloid, saddle and balls. Plane joints allow sliding movement in both directions of one plane. Most of the flat joints are found in vertebrae, hands and legs. The joints of the joints also allow movement in both directions in one plane, which allows either bending or extension, but not displacement. The joints of the joints are located in the middle of the limb and half. Another joint that allows only one -way movement or its opposite is a swivel joint. The swivel joint includes a smooth surrounded bone that can be rotated in place as a wheel. They are present in vertebrae and hip.
condyloid joints are able to move in both directions on two planes, with one direction, which is usually dominant. These joints are also able to encircle a circular movement that includes both aircraft. Example of the condyloid joint is the westěstí. The saddle joints are very similar to condyloid joints, but are more suitable for the perimeter. The thumb joint is a saddle.
The type of synovial joint with the highest freedom of movement is the joint with the ball and disintegration. These joints allow rotation in addition to the extent of the movement allowed by the gable joint. The unique role of rotation can be observed in the twisted effect of the opening of the container lid, which would not be possible without the joint with the ball and the decaying arm.
