Synovial joints are characterized by the presence of a joint cavity. The synovial fluid is produced by the synovial membrane. Cartilage is a soft, spongy connective tissue. Key: •Ball and Socket Joint •Hinge Joint •Pivot Joint •Gliding Joint •Saddle Joint •Condyloid Joint . gliding joints) Hinge joints: motion is along a single plane (uniaxial) and permits flexion and extension only (eg. Illustrations of Synovial Joints by Julie Ridge contains mechanical and biological renderings of the six different joint types (Pivot joint: elbow, Hinge joint: elbow, Ball and socket joint: hip, Gliding joint or plane joint: ankle, Condylar joint: wrist, Saddle joint: thumb) as six different files . A synovial joint is defined by the presence of a fluid-filled joint cavity contained within a fibrous capsule. 0000127011 00000 n Diarthroses are freely movable articulations. The walls of this space are formed by the articular capsule, a fibrous connective tissue structure that is attached to each bone just outside the area of the bone’s articulating surface. 0000003845 00000 n The movement range is defined (i.e., limited) by the joint capsule, supporting ligaments and muscles that cross the joint.

The shape of the joint affects the type of movement permitted by the joint (Figure 1). Joint surround by articular capsule made up of fibrous capsule lined by synovial membrane. These joints can be described as planar, hinge, pivot, condyloid, saddle, or ball-and-socket joints. The synovial membrane contains specialized cells called synoviocytes. Being the link of a bone to bone and help keep the joint together 0000127278 00000 n <]>> 0000006515 00000 n Being a ‘shock absorber’ due to their elasticity, which protects the joint different terms are used. The joint is enclosed in a fibrous joint capsule lined by the synovial membrane. The smooth and slippery lubricated surface of the articular cartilage covers the ends of bones, allowing the sliding of bones at the joint without rubbing each other. ● Sliding occurs in all synovial joints to a certain extent, but in these joints, called gliding or plane joints, the articular surfaces are normally fairly flat and slide on each other in one or more directions. Time to test your knowledge or ask any questions : In synovial joints, the ends of the bones are covered with cartilage (called articular cartilage) which cushions the joint and prevents friction and wear and tear between the bone ends.
