Joint range of motion

Joint range of motion, We distinguish the various joint motion, namely: bullet joints, joints hinge, swivel joints, sliding joints, and saddle joints.

Joint range of motion, a. Bullet joints, ie joints that allow movement to
all direction (free movement). Both ends of the hump-shaped and hollow. One end of the bone-shaped bent and fit into the grooves the other end of the bone. This form allows freer movement in the form of pivot joints other three. For example:
the relationship between bones thigh with pelvic girdle, upper arm bone with the shoulder joint.

b. Hinge joints, ie joints that allow movement to occur one direction only (compare with the door hinges). For example: joints on elbow, knee joints and the joints in the fingers and toes. c. Swivel joints, ie joints one bone moves.
