Abstract
The incidence of muscular variations is way less frequent than that of vascular variations. Among these, supernumerary heads are quite common alongside their original heads. The Biceps Brachii muscle is one such muscle that exhibits variable morphology concerning its origin,insertion and innervation. The most typical variant, however, is said to be the three-headed Biceps Brachii muscle; these supernumerary heads often originate along the middle 2/3 humeral shaft. During routine dissection of a 10% formalin-fixed upper extremity of a 75-year-oldmale of North Indian male, a bilateral tricipital biceps brachii muscle is revealed. The origin of thethird head of the biceps brachii took place in the area between the insertion of the Coracobrachialis and the origin of the Brachialis. These extraneous heads have many clinical implications as these mightbe confusing for the surgeons operating in this field, and if these are present on either side, theymight be misunderstood for soft tissue malignancies. Hence, comprehension ofsuch differencesplays a pivotal role.
