All of the body's condyloid, or ellypsoid, joints are types of joints in a larger group called synovial joints.

Synovial joints are the most abundant type of joint in the human body, allowing the most extensive range of movement of any type of joint. Common to all synovial joints is a layer of cartilage covering the moving parts, as well as a capsule filled with synovial fluid to cushion and lubricate the working parts as they rub together.
