1. The region of the upper limb between the shoulder and elbow is known as the arm. Muscles of the arm are responsible for moving the shoulder and elbow joints. The region between the elbow and wrist is known as the forearm. Forearm muscles are responsible for moving the wrist and finger joints. Upper limb muscles are often identified by their distal insertion. Fill in the name of the muscle that matches the description of the insertions below: - A. B. C. D. E. Tendon inserts onto the deltoid tuberosity. - A. B. C. D. E. Tendon inserts onto fingers 2-4 of the hand (not the thumb). - A. B. C. D. E. Tendon inserts onto the olecranon process on the posterior ulna. - A. B. C. D. E. Tendon inserts onto the radial tuberosity on the anterior radius. - A. B. C. D. E. Tendon inserts into the fascia on the palm of the hand. A. Extensor digitorum B. Triceps brachii C. Biceps brachii D. Palmaris longus E. Deltoid
