Median nerve Anatomy Animation - Origin, Course, Branches and Median nerve injury
The median nerve is one of the five main nerves originating from the brachial plexus and provides motor and sensory innervation to parts of the forearm and hand.
origin
----------
lateral root: lateral cord of the brachial plexus (C5, C6, C7)
medial root: medial cord of the brachial plexus (C8, T1)
course: laterally to the axillary artery, descends in the arm between biceps brachii and triceps brachii muscles, courses through the forearm with the ulna nerve and vessels before entering the carpal tunnel to the hand
major branches: anterior interosseous nerve, palmar cutaneous branch, motor branch in the hand
motor supply: flexor compartment of the forearm, thenar and intrinsic hand muscles
sensory supply: skin over thenar eminence, palmar aspect of the thumb, index, middle finger and radial half of the ring finger
