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

Introduction Biceps brachii muscle belongs to the flexor group of muscles in arm. As Biceps brachii is double headed muscle. It is one of the known variable muscles of human body in terms of number and morphology. Material and Method During routine human cadaveric dissection for the purpose of teaching medical undergraduates in our department. The upper limb of embalmed adult male cadaver was dissected as per the standard method to note the origin, insertion, and nerve supply of biceps brachii. Results The three headed biceps brachii was found unilaterally on right side in adult male cadaver. The long and short head had normal origin, but third head originated from humerus below insertion of coracobrachialis and inserted with main muscle belly and innervated by musculocutaneus nerve. Conclusion Variant biceps brachii may confuse a surgeon who performs procedures on the arm and may lead to iatrogenic injuries. The surgeons and traumatologists have to keep such muscular variations in mind. So the knowledge of existence of its variation is important for anaesthetists and surgeons.

Background: The biceps brachii is an important muscle of anterior compartment of arm. It shows frequent anatomic variability due to presence of supernumerary heads. Knowledge of the existence of the third head of biceps brachii is important for surgeons. Keeping this in mind a study was planned to see the incidence of additional head of biceps brachii in sample Indian population and to compare it with other racial groups.Methods: The study was carried out on 30 cadaveric upper limbs. The upper limbs were dissected and studied for the presence of additional head of biceps brachii. The attachment and nerve supply of the additional head was carefully observed, recorded and documented.Results: Out of 30 limbs which were dissected, additional head of biceps brachii was found only in two limbs. In both the cases the additional head was present only on the right side and arose from the anterior surface of humerus, superomedial to the origin of brachialis. The additional head fused with the common bulk of the muscle and was inserted into the radial tuberosity and bicipital aponeurosis. The extra heads of biceps brachii muscle received branches from musculocutaneous nerve.Conclusions: Biceps brachii is one of the commonest muscles showing variations. The additional head is not only of academic importance, but its knowledge also helps clinicians in managing fractures of humerus and nerve entrapment.

AbstractMany authors have reported and classified several anatomical variations between the musculocutaneous (Mc) and median (Me) nerves, regarding their origin, number, and proximity with the coracobrachialis muscle. There also are, in the scientific community, records classifying the origin of supernumerary heads of the biceps brachii muscle. However, the occurrence of both aforementioned variations in the same arm is very uncommon. During a routine dissection of the right upper limb of a male cadaver, a third head of the biceps brachii was found originating from the fibers of the brachialis muscle, as well as a communicating branch between the Mc and the Me nerves, in the same limb. The objective of the present case report is to describe these multiple variations found, relating them and discussing their relevant clinical implications.

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.

Abstract Background and aims : The biceps brachii is a large fusiform muscle in the flexor compartment of the arm. In terms of the number and morphology of its head, the biceps brachii muscle is one of the most variable muscles in human body. The present study explores the importance of such variations. Materials and methods: The upper limbs of embalmed human cadavers (fixed in 10 % formaldehyde solution) were included in present study. Total 36 (72 upper limbs) cadavers were studied by dissection. Results: Among the 72 superior extremities studied, six (8.33%) arms were found to have a three- headed biceps brachii muscles. The variation was present in the left arm of four males and one female. The variation was present in the right arm of one male. Conclusion : Presence of third head of biceps brachii muscle might increase its kinematics. Supernumerary heads of biceps brachii muscle may become significant in pre-operative procedure and during surgery of upper limb.
