| Introduction: The biceps brachii muscle belongs to the flexor group of muscles in the arm. It is the only flexor of the arm crossing the shoulder joint as well as the elbow joint, thereby acting on both the joints. The biceps brachii muscle is known to show variations in the number of papers.
Materials & Methods: The routine dissection of the brachial region of a man cadaver in the dissection hall of medical college at Zabol University of Medical Sciences.
Findings: An accessory head of biceps brachii muscle has been observed unilaterally on the right upper limb of male cadaver. Whereas the two heads of the biceps brachii muscles arose from their usual position, but the accessory head arose from deep fascia of the deltoid muscle and the pectoralis major muscle on the arm. The accessory head was found to fuse with the common belly of the muscle well before the bicipital tendon and its aponeurosis. This accessory head was supplied by a branch of the musculocutaneous nerves. This supernumerary head was supplied by the brachial vessels.
Discussion & Conclusion: Different positions for accessory head of biceps brachii muscle is observed. Being aware of such variations is of importance both for anatomists and clinicians, especially for plastic surgeons in flap surgery of arms. |
