Where does the short head of the biceps brachii originate?

• A. Supraglenoid Tubercle
• B. Coracoid Process
• C. Intertubercular Groove
• D. Lateral Epicondyle

Answer: (B)

Two heads of the biceps brachii come from different places on the scapula. The short head starts at the coracoid process, while the long head starts at the supraglenoid tubercle. They join to form a single tendon that inserts on the radial tuberosity. The coracoid process is a small anterior projection on the scapula from which the short head of the biceps originates (along with other nearby structures). The intertubercular groove on the humerus is where the long head tendon travels, not where the short head originates, and the lateral epicondyle is a distal humeral site for wrist-extensor muscles. So, the short head originates from the coracoid process.
