ANATOMY

Detailed explanation-1: -The joint cavity contains synovial fluid, secreted by the synovial membrane (synovium), which lines the articular capsule . This fluid-filled space is the site at which the articulating surfaces of the bones contact each other.

Detailed explanation-2: -The synovial cavity can be defined as the space that is found in between the segments of the bones and the articular cartilage. The synovial cavity is covered by the synovial membrane and it is filled with the synovial fluid.

Detailed explanation-3: -Synovial fluid is present in joint cavities and serves a number of important roles in maintaining joint health and mobility. It forms as a plasma ultrafiltrate, with additional components produced from synoviocytes. The synovial membrane lines the inner surface of the joint cavity.

Detailed explanation-4: -A synovial joint, also known as diarthrosis, joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones’ articulating surfaces.

Detailed explanation-5: -Synovial joints are joints that have a space between the adjoining bones. The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses.
