The type of joint depicted in the image is a Synovial joint. To identify this joint type, we consider the following characteristics:
Articular cartilage covers the ends of the bones, providing a smooth surface for movement.
A joint cavity filled with synovial fluid is present, offering lubrication and nourishment to the cartilage.
The joint is enclosed by a fibrous articular capsule, providing stability.
Synovial membranes line the inner surface of the capsule, producing the synovial fluid.
These joints can facilitate a wide range of movements including gliding, angular, and rotational motions, which is characteristic of synovial joints.
Given these features, it's evident that the joint in question is indeed a synovial joint, distinguishing it from other joint types like syndesmosis, synarthrosis, or symphysis which lack these combined characteristics.
