Three headed Biceps brachii with variant communication between median and musculocutaneous nerve.pdf (original) (raw)

The biceps brachii muscle is a key flexor and supinator of the forearm, with notable anatomical variations in its structure and nerve communications. This case report describes the presence of an accessory (third) head of the biceps brachii in two cadavers, aged 50 and 45, and explores the variant communication between the median and musculocutaneous nerves. Understanding these variations is crucial for improving surgical outcomes and diagnostic accuracy in clinical settings, particularly in relation to potential misdiagnoses of muscle tears and nerve compressions.
