El coracobraquial es un músculo situado en el compartimento anterior de la parte superior del brazo. Inserciones: se origina en la apófisis coracoidea de la escápula. El músculo atraviesa la axila y se inserta en la cara medial de la diáfisis del húmero (a nivel del tubérculo deltoideo). Función: flexión del brazo por el hombro. Además, es un aductor débil del hombro. Inervación: nervio musculocutáneo. Irrigación sanguínea: arteria braquial.

Learn More Frequent questions What is the coracobrachialis muscle? The coracobrachialis is a muscle located in the anterior compartment of the upper arm. It plays a role in flexing the arm at the shoulder and acts as a weak adductor of the shoulder joint. Where does the coracobrachialis muscle originate and insert? The coracobrachialis originates from the coracoid process of the scapula and inserts on the medial surface of the diaphysis of the humerus, near the deltoid tuberosity. What is the primary function of the coracobrachialis? The primary function of the coracobrachialis is to flex the arm at the shoulder joint. Additionally, it assists in adducting the shoulder. Which nerve innervates the coracobrachialis muscle? The coracobrachialis is innervated by the musculocutaneous nerve, which provides the necessary motor function for its actions. What is the blood supply to the coracobrachialis muscle? The coracobrachialis receives its blood supply from the brachial artery, ensuring adequate oxygen and nutrients for its function.
