What is the function of the synovial membrane?
When the two bones are joined to form a joint, scratching bones against each other would quickly become painful without any type of padding or lubricant. The synovial membrane determines that padding and lubricant. It is a tissue that acts as a pillow, but more importantly, the synovial membrane excludes the lubricant that allows both bones to move freely against each other. Like the automotive engine, it needs oil to prevent the moving or freezing of its moving parts, the moving joints of the body should be maintained well.
The synovial membrane is found only in synovial joints, which are the most common joints in humans. The types of synovial joints include knees, elbows, shoulders, wrists and hips. Although some synovial joints have a greater range of movement than others, they can all move to some extent. The ability of the joints to move is directly proportional to the risk that the joints can be more easily injured. In other words, the larger Moviment is possible, the greater the chance of injury, as can be seen in the knee.
Human knees have the largest range of movement of any joints in the body. Since their structure represents all synovial joints, there may be a useful explanation of the knee structure. The knee is a place where the femur and shin meet; At the intersection is covered with Kneecap or Patella, which in turn connects to the joint capsule. In the joint capsule, synovial fluid, produced by the synovial membrane, smears the ends of the bones and cartilage between them.
This lubrication is essential for easy movement and prevention of joint pain. Some diseases such as rheumatoid arthritis may cause the body of its own defense attacking healthy areas. When the synovial membrane is subjected to such an attack, it cannot produce sufficient synovial fluid, resulting in reduced mobility and increased Pain. Because the synovial membrane also works as a seal to maintain the fluid in the joint, damaged by membraneThe wound can lead to leakage to areas where it does not belong.
If the leak is too large, or the synovial membrane is too seriously damaged, the cartilage in the joint does not have to receive sufficient supply of blood and other nutrients. When this happens, the cartilage can literally starve to death. It is also possible that the body can react by relaxing enzymes that can consume cartilage, resulting in further pain and motion in the joint.
