Six Asymmetric Bilateral Additional Heads Of Biceps Brachii Muscle Observed in a Cadaver

Anatomic variation of the biceps brachii muscle (BBM) is frequently observed; its pattern diverse and clinically important. During educational dissection a 78-year-old Korean male cadaver, six additional asymmetrical heads were found on both sides. On right side, two originated from humerus; musculocutaneous nerve passed between these short head BBM. Four left anterior to BBM, one which pectoralis major muscle. Posterior tendons coracobrachialis belly humerus. The pierced continued distally passing BBM located posterior It then gave off variant median nerve. sides, long had normal origins, insertions, courses. This novel has various clinical embryological implications.
