Introduction: Musculocutaneous nerve is derived from the lateral cord of brachial plexus and supplies the muscles of the arm. Initially the nerve accompanies the lateral side of third part of axillary artery and then pierces the coracobrachialis muscle after supplying it, passes downwards and laterally in between biceps brachii and brachialis sending branches to both and continues as lateral cutaneous nerve of the forearm. Variations ofmusculocutaneous nerve is important for surgeons, orthopedic surgeons and traumatologists, so a detailed cadaveric study of musculocutaneous nerve was done to observe the variations.Material & Methods: Musculocutaneous nerve was studied in 50 human cadavers (30 males and 20 females) of age group 40-60 years at Department of Anatomy, Subharti Medical College, Meerut, India.Results: Musculocutaneous nerve was present in all the cases and was piercing the coracobrachialis muscle. In 4% of the cases, the nerve was rejoining the median nerve after piercing the coracobrachialis.
