What it concludes

• Biceps anatomy consists of a long head and short head originating from different areas and merging into a single tendon inserting on the radius.
• The biceps is one of the most morphologically variable muscles in the upper limb, with varying head counts and tendon insertions.
• On average across studies, the biceps makes up 46% of elbow flexor volume, the brachialis 37%, and the brachioradialis 17%.
• Both long and short head cross-sectional area studies found the long head has a greater physiological cross-sectional area.
• Biceps contain slightly more fast-twitch fibers (54.5%) than slow-twitch fibers (45.5%).
• Biceps long and short head activity is greatest in supination and lowest in pronation during elbow flexion at various angles, while the opposite is true for the brachialis and brachioradialis brachii muscles and the brachioradialis brachii muscles and the brachioradialis brachii muscles and the brachioradialis brachii muscles and the brachioradialis brachii muscles and the brachioradialis
