Description[edit source]
Origin[edit source]
Origin of Short Head: Apex of the coracoid process of
the scapula.
Origin of Long Head: Supraglenoid tubercle of the
scapula.
Insertion[edit source]
Tuberosity of the radius and aponeurosis of the biceps brachii (lacertus fibrosus).
Nerve[edit source]
Musculocutaneous C5, 6.
Artery[edit source]
Function[edit source]
Flexes the shoulder joint. The short head assists with shoulder adduction. The long head may assist with abduction if the humerus is laterally rotated. With the origin fixed, flexes the elbow joint, moving the forearm toward the humerus and supinates the forearm. With the insertion fixed, flexes the elbow joint, moving the humerus toward the forearm, as in pull-up or chinning
exercises.
