The median nerve derives from the lateral and medial cords of the brachial plexus. Initially, it travels down on the medial side of the arm along with the brachial artery.
At the elbow, it will continue its course under the aponeurosis of the biceps and between the two heads of the pronator teres. Once it gives off the antebrachial interosseous branch, it will initiate its trajectory in the forearm between flexor digitorum profundus and the flexor digitorum superficialis muscles, serving as their supply.

The median nerve then passes through the carpal tunnel beneath the flexor retinaculum, and divides to form two common palmar digital nerves.
