A planar joint allows gliding or sliding movements between flat or slightly curved surfaces.
A pivot joint permits rotational movement around a single axis.
A ball-and-socket joint allows movement in multiple axes and planes, including rotation.
A hinge joint permits movement primarily in one plane, like flexion and extension.
A condylar joint allows movement in two planes without rotation (biaxial).
A saddle joint permits biaxial movement with greater freedom than condylar joints.
An anaxial joint allows only gliding movements without rotation or angular motion.
A uniaxial joint allows movement around one axis only.
A biaxial joint allows movement around two axes.
A multiaxial joint allows movement around multiple axes and planes.
Flexion decreases the angle between two bones at a joint.
Extension increases the angle between two bones at a joint.
Abduction moves a limb away from the midline of the body.
Adduction moves a limb toward the midline of the body.
Medial rotation turns a limb toward the midline of the body.
Lateral rotation turns a limb away from the midline of the body.
Protraction moves a body part forward in the horizontal plane.
Retraction moves a body part backward in the horizontal plane.
Elevation raises a body part superiorly.
Depression lowers a body part inferiorly.
Pronation rotates the forearm so the palm faces downward or posteriorly.
Supination rotates the forearm so the palm faces upward or anteriorly.
Dorsiflexion bends the foot upward toward the shin.
Plantarflexion bends the foot downward away from the shin.
Inversion turns the sole of the foot medially.
Eversion turns the sole of the foot laterally.
