HN210 Lecture Notes - Lecture 10: Radial Nerve, Common Flexor Tendon, Latissimus Dorsi Muscle
Document Summary
Arise also from antebrachial facia covering muscles and. These 2 muscles have attachments along the skin. O: medial epicondyle and coronoid process of ulna. A: if muscles contracts it is going to roll radius medially, I: lateral surface of radius (middle of shaft) weak forearm flexor because it is really close to the anchor point. Inserts into the wrist on the radial side. Base of the 2nd digit (index finger) A: flex hand at wrist, may also produce abduction and. I: base of 2nd metacarpal assists with pronation. When pronator teres contracts with muscle will shorten. A: not a major mover (10% of the population does not have this muscle) helps with flexion of the hand. O: common flexor tendon and proximal 2/3 of posterior surface of ulna. I: pisiform bone on ulna side of hand. A: good flexor of wrist and adduction (ulnar deviation) Looks like 4 muscles but it is one muscle.
