ANTR 350 Lecture Notes - Lecture 28: Obturator Nerve, Vastus Medialis, Hip
Document Summary
Anika, list the 4 muscles that make up the rotator cuff (see figure 12. 5 rotator cuff. Muscles); describe the action of each of the rotator cuff muscles. List the muscles contained in the anterior and posterior compartments of the arm and specify the nerve that innervates each compartment. Anterior compartment: biceps brachii, coracobrachialis and brachialis (musculocutaneous nerve) Describe the primary actions of the muscles located in the anterior and posterior compartments of the forearm and identify the nerve(s) that innervate each compartment. Anterior: flexion (of wrists and fingers) and pronation (ru); innervated by median nerve. Posterior: extension (of wrist and fingers) and supination (ru); innervated by radial nerve. Anika describe the anatomical structures that form the carpal tunnel (clinical view, The space between the carpal bones and the flexor retinaculum. Describe how the muscles of the thumb (thenar group) are affected by carpal tunnel syndrome. The muscles may atrophy as their nerve supply is diminished.
