Which muscle originates at the coracoid process of the scapula?

• A. Long Head of Biceps Brachii
• B. Short Head of Biceps Brachii
• C. Triceps Brachii
• D. Deltoid

Answer: (B)

Identifying where muscles attach to the scapula is being tested here. The coracoid process serves as the origin for the short head of the biceps brachii. The long head of the biceps brachii originates from the supraglenoid tubercle, not the coracoid. The triceps brachii has origins at the infraglenoid tubercle (for the long head) and on the humerus for the other heads, while the deltoid originates from the clavicle, acromion, and spine of the scapula. Therefore, the muscle that originates at the coracoid process is the short head of the biceps brachii.
