[Anomalies of the biceps muscle of the arm].
The author studied the biceps brachii muscle with respect to the incidence of accessory heads (Caput accessorium) and compared the data obtained with those in different human races. Dissection of 552 human arms in Teheran and Mainz, revealed the presence of 2 biceps brachii muscles with accessory heads one of a right arm with one accessory head, the other on a left arm with two accessory heads. From data in the literature it is concluded that in the white race the incidence of accessory heads of the biceps brachii m. is relatively rare, high in the yellow race and intermediate in negroes.
