The long head of the biceps brachii is an important stabilizer of the glenohumeral joint. Where does its tendon of origin attach?
- A Coracoid process of the scapula
- B Supraglenoid tubercle of the scapula ✓
- C Infraglenoid tubercle of the scapula
- D Acromion process
Correct answer: B. Supraglenoid tubercle of the scapula
Explanation
The long head of biceps brachii originates from the supraglenoid tubercle at the apex of the glenoid fossa and from the glenoid labrum. Its tendon passes through the joint cavity of the shoulder and exits via the intertubercular (bicipital) groove. By contrast, the short head originates from the coracoid process (along with coracobrachialis).
