A rare variant branch from the lateral cord and a communicating branch between the musculocutaneous and median nerve

Abstract

During routine educational gross anatomy dissections of the upper extremities, one right upper limb was observed to have an unusual branch from the  lateral cord that pierced coracobrachialis towards its origin. This variant branch emerged from the lateral cord before it branched to give its contribution  to the median nerve and musculocutaneous nerve in the axilla. The same limb also had a communicating branch between the musculocutaneous nerve  to the median nerve at the mid arm level. These variations may be of interest to neurologists, anatomists and surgeons operating in the upper limb  region.
