Abstract EN
The brachial plexus innervates the upper extremities.
While variations in the formation of the brachial plexus and its terminal branches are quite common, it is uncommon for the median nerve to innervate the muscles of the arm.
During the dissection of an elderly male cadaver at the Department of Anatomy, All India Institute of Medical Sciences, New Delhi, India, in 2016, the coracobrachialis muscle was found to be supplied by a direct branch from the lateral root of the median nerve and the musculocutaneous nerve was absent.
The branches of the median nerve supplied the biceps brachii and brachialis muscles and the last branch continued as the lateral cutaneous nerve of the forearm.
These variations may present atypically in cases of arm flexor paralysis or sensory loss on the lateral forearm.
Knowledge of these variations is important in surgeries and during the administration of regional anaesthesia near the shoulder joint and upper arm.
