With regards to the biceps brachii:

Question

Quizplus · Accepted Answer

The biceps brachii is known for its role in supinating the forearm and flexing the elbow. The long head originates from the supraglenoid tubercle of the scapula, not the greater tuberosity, and the short head originates from the coracoid process of the scapula, not the acromion. It is innervated by the musculocutaneous nerve, not the median nerve. The two heads of the biceps brachii merge to form a single muscle belly in the upper arm, but this is not specifically mentioned in the options.
