Document Summary

April 3 ch 19: elbow, forearm, wrist and hand. Pronation and supination occur in the elbow between the joints of the radius and ulna. Remember arm is supinated when holding a bowl of soup. When supinated the radius and ulna are parallel. Ulna has an l so remember its lateral. Rcl is on the lateral side of the elbow and inserts onto the annular ligament and originates off the lateral epicondyle. Flexion and extension occur in the elbow: muscles involved in flexion are biceps brachii, brachilais, and brachioradialis. In a supinated position the biceps brachii is isolated. In the beer drinking pose, the brachioradialis is isolated: a pronated position will isolate the brachialis, pronator muscles are prontator teres and quadrates, biceps brachii is a 2 joint muscle, triceps is involved in elbow and shoulder extension. If there is something wrong in internal organs, the pain could be referred to the elbow or shoulder.
