The nerve that passes through the coracobrachialis muscle is the musculocutaneous nerve.
The musculocutaneous nerve pierces the coracobrachialis muscle and supplies it with innervation.
The coracobrachialis muscle is involved with in the flexion and the adduction of the shoulder. That is to say, raising the arm and bringing the arm across the chest, respectively.
Either the triceps brachii or the coracobrachialis.
no. Only one join
The coracobrachialis attaches proximally to the coracoid process of the scapula and distally to the middle of the medial border of the humerus.
Coracobrachialis Muscle
The coracobrachialis muscle acts as a third-class lever in the body. It helps flex and adduct the arm at the shoulder joint by pulling on the coracoid process of the scapula when contracting.
The bicep flexes the arm at the elbow.
The muscles that horizontally flex the shoulder are the Pectoralis Major and the coracobrachialis.
The Triceps Brachi is the antagonist for the Corachobrachialis, the Brachialis and the Biceps Brachi
The coracobrachialis muscle action is to flex and adduct the arm at the shoulder joint. It also helps stabilize the shoulder joint during arm movements.
