2
CONDYLOID JOINT oval-shaped condyle of one bone fits into an elliptical cavity of another. Ex. Metacarpals and phalanges Rotational movement is not possible
3
GLIDING JOINTS Nearly flat, slightly curved Wrist, ankle, vertebrae Allow sliding and twisting
4
HINGE JOINT Convex surface of one bone fits into the concave surface of another. Ex. Elbow, phalanges
6
PIVOT JOINT Cylindrical surface of one bone rotates within a ring formed of bone and ligament. Rotation around a central axis. Ex. Proximal end of radius and the ulna.
7
SADDLE JOINT Between bones whose articulating surfaces have both concave and convex regions. Carpal and metacarpal bones of the thumb.

JOINT MOVEMENTS Flexion: bending parts at a joint so that the angle between them decreases and the parts come closer together. Extension: straightening parts at a joint so that the angle between them increases. Dorsiflexion: bending the foot at the ankle toward the shin.
10
Plantar flexion: bending the foot at the ankle toward the sole
Plantar flexion: bending the foot at the ankle toward the sole. Hyperextension: excess extension of the parts at a joint, beyond the anatomical position (bending the head back beyond the upright position).
11
Abduction: moving a part away from the midline
Abduction: moving a part away from the midline. Adduction: moving a part toward the midline. Rotation: moving a part around an axis. Circumduction: moving a part so that its end follows a circular path. Pronation: turning the hand so that the palm is facing downward or posteriorly. Supination: turning ht hand so that the palm is facing upward.
12
Eversion: turning the foot so that the sole faces laterally
Eversion: turning the foot so that the sole faces laterally. Inversion: turning the foot so that the sole faces medially. Retraction: moving a part backward. Protraction: moving a part forward. Elevation: raising a part. Depression: lowering a part.
