Unilateral Absence of the Musculocutaneous Nerve - A Case Report

Abstract

The musculocutaneous nerve, which derives from the brachial plexus's lateral cord and gets fibers from C5, C6, and C7, innervates the muscles of the anterior compartment of the arm. The nerve travels between the brachialis and biceps brachii, piercing the Coracobrachialis muscle. A male cadaver's left upper limb was routinely dissected, and it was noted that the median nerve's branches supplied the muscles in the left arm's anterior compartment whereas the musculocutaneous nerve was absent. Understanding musculocutaneous nerve variations is essential for surgical interventions.
