Abstract

Unusual neural and muscular variations in the right upper limb were noted during anatomical dissection of a 54-year-old male cadaver. The absence of the musculocutaneous nerve was correlated with a three-headed biceps brachii muscle. The distribution of muscular branches innervating the anterior compartment of the muscles of the arm was different to the cases described in literature hitherto. This report contains a comparison of various instances where the musculocutaneous nerve is absent. We discuss the embryological explanation for this anomaly and its clinical results. It is important to be aware of such possible anatomical variations during clinical practice.
