- Coracobrachialis muscles
The coracobrachialis muscle is one of the three muscles of the anterior compartment of the arm. It sits beneath the biceps brachii, inserting via a flat tendon into the medial shaft of the humerus.
- origin: coracoid process of scapula
- insertion: via a flat tendon onto the midportion of the medial surface of humerus
- innervation: musculocutaneous nerve (C6 and C7)
- action: arm flexion and adduction
