During routine undergraduate dissection in Anatomy department, bilateral variations were found in the anterior compartment of the arm in male cadaver of approximately 58 years age. The musculocutaneous nerve was absent on both sides. The muscles in the anterior compartment of the arm except coracobrachialis, which are normally supplied by musculocutaneous nerve, were receiving fibers from lateral side of median nerve.  Coracobrachialis was supplied by thin nerve arising directly from lateral chord. We will be reporting this case with its clinical significance.
