A case with multiple anomalies in the upper limb.

During routine educational dissection studies, we encountered multiple nervous and arterial anomalies in a 60-year-old embalmed male cadaver. The arterial anomalies were observed on the right side. The superficial brachial artery originated from the axillary artery under the pectoralis minor muscle. There was an arch between the superficial brachial and brachial arteries in the cubital fossa. Additionally, a communication was observed between the musculocutaneous and median nerves. Moreover, the coracobrachialis muscle was innervated by an accessory nerve branch originating from the lateral cord of the brachial plexus. All of the nervous anomalies were on the left side. A combination of these variations in the same case has not, to our knowledge, been previously described in the available literature.
