Biceps brachii is a muscle of the anterior compartment of the arm having a long head and a short head. Distally both heads unite to form a common tendon inserting into the radial tuberosity and the bicipital aponeurosis. Most commonly it may have an additional head but presence of four heads and more is relatively very rare. The present study documents the incidence and morphological characteristics of supernumerary head of biceps brachii in adult South Indian cadavers. We studied 40 arms of 20 adult formalin fixed cadavers in the Department of Anatomy, Kasturba Medical College, Manipal, India. The presence of number of additional heads and their details of attachments were studied. We observed presence of supernumerary heads of biceps brachii in 6 (15%) cases, in which having three heads observed in five cases (12.5%) and four heads in one case (2.5%). In one case, we noticed bilateral incidence with three heads on left side and four heads on right side. Knowledge of incidences of such variable numbers of additional heads and pattern of their attachment may facilitate the preoperative diagnosis in addition to the surgical procedures of the upper limbs
