Question

This muscle flexes the forearm and supinates the forearm and wrist. It is served by the musculocutaneous nerve. it has its origin on the supraglenoid tubercle and the coracoid process of the scapula. It inserts on the radial tuberosity of the radius and on the bicipital aponeurosis. ___________

Answer 1

The biceps brachii is the muscle that flexes and supinates the forearm, served by the musculocutaneous nerve, and attaches from the scapula to the radius.

Step-by-step explanation:

The muscle that flexes the forearm, supinates the forearm and wrist, and is served by the musculocutaneous nerve is the biceps brachii. This muscle originates from the supraglenoid tubercle and the coracoid process of the scapula, and it inserts on the radial tuberosity of the radius and the bicipital aponeurosis. The biceps brachii is involved in both the movements of supination and flexion at the radioulnar and elbow joints. Additionally, when flexing the forearm, the brachialis and brachioradialis muscles complement the function of the biceps brachii.
