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

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.

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.

<p>During routine human cadaveric dissection for the purpose of teaching learning of medical undergraduates in our 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 fleshy proximal attachment on humerus between the insertion of the coracobrachialis and the upper part of the origin of the brachialis. This supernumerary head was deep to the other two heads of biceps and was inserted into the bicipital aponeurosis. A branch of musculocutaneous nerve could be traced upto the third head. Long and short heads of biceps were of usual anatomy.</p>

Abstract Background and aims : The biceps brachii is the large muscle of flexor compartment of arm. Normally it arises by two heads (long head and short head) and gets insertion in two parts (tendinous part and aponeurotic parts). The biceps brachii muscle is well known for variation in its origin. These variations can cause compression of brachial artery and median nerve which may pass deep to the accessory head of biceps brachii muscle, and can create problems for surgeons. So the surgeons should keep in mind such variations of biceps brachii muscle. The present study is to find out the variations in the origin of biceps brachii muscle. Material and methods: The present study was conducted in the department of anatomy of Gian Sagar Medical College, Ramnagar, Rajpura district Patiala (Punjab). In this study 32 human cadaveric limbs which were embalmed and fixed in 10% formaldehyde solution were used and these limbs were dissected and variations in origin of the biceps brachii muscle were noted. Results : Out of 32 limbs, 3 limbs (9.38%) were having three heads of biceps brachii muscle in its origin. The variations were found in the right limbs only. Conclusions : The knowledge of accessory head of biceps brachii muscle is important for the surgeons and troumatologists because there can be iatrogenic injury to the third head of biceps brachii muscle.
