The Adherence of Musculocutaneous Nerve to Median Nerve Without Piercing Coracobrachialis Muscle – A Case Report

Adherence of Musculocutaneous Nerve to Median Nerve

Abstract

The brachial plexus has been reported to show different variations with its formation, course, branches and distribution patterns. During routine dissection in the department of Anatomy, College of Medicine and Health Sciences, Bahir Dar University. One such variation was observed, musculocutaneous nerve arises as usual from the lateral cord but unusually, it does not pierce the coracobrachialis muscle rather, the nerve unites with median nerve and forms common trunk and gives branches to the anterior compartment of the arm in the middle of the arm. Considering clinical importance, recognition and knowledge of such possible anatomical variation will be helpful in the field of neurology, anesthesia and surgery.
