The coracoid process of the scapula serves as an attachment site for three muscles: Coracobrachialis – Originates from the coracoid process and inserts on the humerus, assisting in flexion and adduction of the shoulder. Biceps Brachii (Short Head) – Originates from the coracoid process and contributes to elbow flexion and forearm supination. Pectoralis Minor – Inserts onto the coracoid process and helps in scapular protraction and downward rotation. These muscles play a role in stabilising the s

Coracobrachialis Muscle Origin: Coracoid process of scapula. Insertion: Middle third of medial aspect of humerus. Action: Adducts and flexes arm at glenohumeral (shoulder) joint. Innervation: Musculocutaneous nerve (C5-C7). Arterial Supply: Brachial and anterior circumflex humeral arteries. The coracobrachialis muscle is found in the anterior compartment of the arm. It is a strap-like type of skeletal muscle. It is located: - anterior (superficial) to the subscapularis, teres major, latissimus d
