The document contains questions about muscles of the anterior arm. It identifies the coracobrachialis muscle multiple times as arising from the coracoid process of the scapula and attaching to the middle third of the medial aspect of the humerus. It also identifies the biceps brachii muscle as having two heads, one originating from the coracoid process and the other from the supraglenoid tubercle, attaching to the radial tuberosity in the forearm. The brachialis muscle is identified as originating from the distal half of the anterior surface of the humerus and inserting on the coronoid process of the ulna.

36. Complete transection of the musculocutaneous nerve at its
origin
1 will result in impairment of supination of forearm
2 Will cause impaired extension of elbow joint
3 will result in loss of sensation over the lateral aspect of
forearm
4 will result in weakened flexion of elbow joint
5 loss of cutaneous sensation on the anterior aspect of the
elbow region

37. The musculocutaneous nerve is the nerve of the anterior compartment of the
arm and supplies biceps brachii, brachialis and coracobrachialis, before
continuing as the lateral cutaneous nerve of forearm. Thus injury to the
musculocutaneous nerve will result in weakened elbow flexion (due to
paralysis of brachialis and biceps). However, elbow flexion will not be
completely abolished as brachioradialis and the muscles arising from the
common flexor tendon (none of which are innervated by the
musculocutaneous nerve) will be able to flex the elbow to some extent. Injury
to the musculocutaneous nerve will result in significant impairment of
supination due to paralysis of biceps brachii, the principal supinator.
