The variations in the muscles and nerves of the upper limb have been commonly reported and well documented. However, our study describes the coexistence of multiple neuromuscular variations of the arm hitherto not reported, to the best of our knowledge. During routine dissection, we observed an accessory head of coracobrachialis muscle, an additional head of biceps brachii muscle, unusual course of musculocutaneous nerve in the arm and formation of median nerve in the middle of the arm in a single male cadaver. These variations were bilateral. Knowledge of these variations is necessary to avoid complications during various procedures done in Upper Limb.
