Muscles in the arm diagram

The upper arm is located between the shoulder joint and elbow joint. It contains four muscles — three in the anterior compartment biceps brachii, brachialis, coracobrachialis , and one in the posterior compartment triceps brachii. In this article, we shall look at the anatomy of the muscles of the upper arm — their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm — biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC — b iceps, b rachialis, c oracobrachialis. Arterial supply to the anterior compartment of the upper arm is via muscular branches of the brachial artery. The biceps brachii is a two-headed muscle. Although the majority of the muscle mass is located anteriorly to the humerus , it has no attachment to the bone itself. As the tendon of biceps brachii enters the forearm, a connective tissue sheet is given off — the bicipital aponeurosis. This forms the roof of the cubital fossa and blends with the deep fascia of the anterior forearm. The brachialis muscle lies deep to the biceps brachii, and is found more distally than the other muscles of the arm. It forms the floor of the cubital fossa. Fig 1 — The coracobrachialis, biceps brachii and brachialis muscles of the anterior upper arm.
