Which muscle does not attach to the coracoid process?

• A. Triceps brachii
• B. Biceps brachii
• C. Pectoralis minor
• D. Coracobrachialis

Answer: (A)

The coracoid process is a small projection on the scapula that serves as a pointing anchor for several muscles. Three muscles attach there: the short head of the biceps brachii, the coracobrachialis, and the pectoralis minor. The long head of the triceps brachii is the one that does not attach to the coracoid. Its origin is the infraglenoid tubercle of the scapula, while the other heads arise from the humerus, and its tendon inserts on the olecranon of the ulna. So, the muscle that does not attach to the coracoid is the triceps brachii.
