Synovial Joint

s Synovial joints are the most common type of diarthrodial or freely movable joint found in the human body. They are formed by the articulation of two or more bones, each surrounded by a fibrous capsule that serves to maintain joint stability. The joint surfaces of the bones are covered in articular cartilage, which reduces friction as the joint moves. Between the bones, a lubricating synovial fluid is found that helps to reduce friction as the joint articulates. This fluid is secreted by the synovial membrane that lines the fibrous capsule. Synovial joints are found throughout the human body and are important for the normal functioning of the skeletal system and the ability to move freely. By allowing movement in multiple directions, synovial joints help us to perform everyday activities, maintain balance, and participate in physical activities.
