Diarthrotic Joint

Freely movable joint classified functionally, all synovial joints are diarthrotic.

Hinge Joint

A type of joint that allows for flexion and extension, resembling a door hinge.

Ball and Socket Joint

A joint that allows for the most movement, including flexion, extension, abduction, adduction, rotation, and circumduction.

Gliding Joint

A joint where two flat surfaces glide over each other, such as between carpal bones.

Pivot Joint

A joint that allows for rotational movement, as seen between the atlas and axis of the cervical spine.

Ellipsoid Joint

A joint that allows movement in two planes, found between the metacarpals and proximal phalanges.

Saddle Joint

A joint that allows for flexion, extension, abduction, and adduction, such as at the base of the thumb.

Flexion

The movement that decreases the angle at a joint.

Extension

The movement that increases the angle at a joint.

Abduction

Movement away from the midline of the body.

Adduction

Movement towards the midline of the body.

Circumduction

A circular movement that combines flexion, extension, abduction, and adduction.

Pronation

Rotational movement of the forearm that turns the palm down.

Supination

Rotational movement of the forearm that turns the palm up.

Hyperextension
