Hip (Coxal)

Diarthrotic, Synovial, Ball and Socket

A type of joint that does not move at all

Synarthrotic

A joint that moves a little

Amphiarthrotic

A joint that moves freely

Diarthrotic

Joint where the material between the bones is a fibrous connective tissue (sutures, syndesmosis, gomphosis)

Fibrous joint

Joint where adjacent bones are connected with cartilage- usually provide a little movement or none.

Cartilaginous joint

Joints where adjacent bones have a thin layer of articular cartilage over ends of bones and a fibrous joint capsule spanning a cavity between the bones.

Inside of joint capsule has a thin synovial membrane that makes synovial fluid to cushion and lubricate the joint

Synovial joint

A joint where bones can only move along one axis to flex or extend.

Hinge joint

A type of joint where a condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.

Condyloid joint

A joint where a partially spherical end lies in a socket, allowing multidirectional movement and rotation.

Ball and Socket joint

A joint that allows one bone to rotate around another.

Pivot joint

Joint where bones meet at ~flat articular surfaces. Bones move past one another along the plane of the joint.

Gliding (planar) joint

Joint where adjacent surfaces at the ends of each bone are saddle-shaped, with the saddles meeting to form an X shape.
