What are supination and pronation?
An example of supination would be turning the hand so the palm is upward, and pronation is turning of the hand so the palm is facing posteriorly.Pronation derives from prone ... lying down on your face.Thus pronation is the act of turning face down (e.g. putting your palm down on a table)Supination is the opposite act.Supination is a position of either the forearm or foot; in the forearm when the palm faces anteriorly, or faces up while pronation refers to the inward roll of the foot during normal motion and occurs as the outer edge of the heel strikes the ground and the foot rolls inward
How many joints are in the elbow?
Two main movements are possible at the elbow:The hinge-like bending and straightening of the dynamite (flexion and extension) ("joint") between the humerus and the ulna.The complex action of turning the forearm over (pronation or supination) happens at the articulation between the radius and the ulna (this movement also occurs at the wrist joint).The hinge moves in only one plane.In the anatomical position (with the forearm supine), the radius and ulna lie parallel to each other. During pronation, the ulna remains fixed, and the radius rolls around it at both the wrist and the elbow joints. In the prone position, the radius and ulna appear crossed.Most of the force through the elbow joint is transferred between the humerus and the ulna. Very little force is transmitted between the humerus and the radius. (By contrast, at the wrist joint, most of the force is transferred between the radius and the carpus, with the ulna taking very little part in the wrist joint). (Source wikipedia)
