During routine human cadaveric dissection for the purpose of teaching learning of medical undergraduates inour department, third head of the biceps brachii muscle was found bilaterally in a 67 years old male cadaver. Bilaterally symmetrical third head was found with ß eshy proximal attachment on humerus between the insertionof the coracobrachialis and the upper part of the origin of the brachialis. This supernumerary head was deep tothe other two heads of biceps and was inserted into the bicipital aponeurosis. A branch of musculocutaneousnerve could be traced upto the third head. Long and short heads of biceps were of usual anatomy.doi: http://dx.doi.org/10.3126/mjsbh.v12i2.12931

Unknown Case

CONTEXT: The musculocutaneous nerve is one of the terminal branches of the lateral fasciculus of the brachial plexus, and is responsible for innervation of the flexor musculature of the elbow and for skin sensitivity on the lateral surface of the forearm. Its absence has been described previously, but its real prevalence is unknown. CASE REPORT: A case of absence of the musculocutaneous nerve that was observed during the dissection of the right arm of a male cadaver is described. The area of innervation was supplied by the median nerve. From this, three branches emerged: one to the coracobrachialis muscle, another to the biceps brachii muscle and the third to the brachialis muscle. This last branch continued as a lateral antebrachial cutaneous nerve. This is an anatomical variation that has clinical-surgical implications, considering that injury to the median nerve in this case would have caused unexpected paralysis of the flexor musculature of the elbow and hypoesthesia of the lateral surface of the forearm.
