ABSTRACT
Musculocutaneous nerve is a branch of lateral cord of brachial plexus. It innervates muscles of flexor compartment of arm and continuous as the lateral cutaneous nerve of forearm without any communication with median or any other nerves.1 The present report describes a case of variation in musculocutaneous nerve observed in adult male cadaver during routine dissection on the right side. The musculocutaneous nerve did not pierce coracobrachialis muscle and gave a communicating branch to median nerve in the middle of the arm. It is important to be aware of this variation while planning a surgery in the region of axilla or arm, as these nerves are more liable to be injured during operations.
ABSTRACT
During dissection of abdomen by the undergraduate medical students three accessory renal arteries were observed on the right side. The superior accessory artery was a small vessel arising from aorta just above the normal renal artery. It entered the anterior surface of kidney just below the upper pole. The middle and inferior arteries were caudal to the normal renal artery. The middle artery was arising from testicular artery and entered the anterior surface of kidney below the hilum. The inferior artery was arising from aorta just above its bifurcations and entered the lower pole of kidney. The importance of accessory renal arteries in surgical procedures of the posterior abdominal wall and renal transplantation are discussed.
