The median nerve is a mixed motor and sensory nerve of the arm that contains nerve fibers from segments C6 to Th1 and arises from the Brachial plexus[^1].
Anatomy
The median nerve runs in the medial bicipital groove, superficial to the brachial artery, to the cubital fossa, where it passes between the two heads of the pronator teres muscle to enter the forearm. The median nerve runs between the flexor digitorum superficialis and flexor digitorum profundus muscles to the wrist. Before passing through the carpal tunnel, it lies superficially between the tendons of the flexor carpi radialis and palmaris longus muscles. Within the carpal tunnel, the median nerve divides into its terminal branches.
Clinical relevance
Proximal injury to the median nerve results in a Hand of benediction. As the nerve passes through the carpal tunnel, compression injury may occur, leading to Carpal tunnel syndrome .
