Abstract

Various types of variations have been associated with the proximal attachment of the biceps brachii muscle (BBM). The bulk of the reports, been studies done on Caucasian subjects. This is a case report on the supernumerary and variant heads of the proximal part of BBM in three young male adult Nigerian cadavers. Supernumerary occurrence of the head of BBM noted was that of 3 heads and this occurred unilaterally. Another variation noted in another subject was that of the origin of the short head of biceps brachii (SHB) from the acromion and from the supraglenoid tubercle, which also occurred unilaterally. These findings were compared with other documented reports.
