Median nerve

Nervus medianus

Formed from the lateral and medial cords of the brachial plexus (C5-T1). It descends through the arm without giving branches, passes through the cubital fossa, runs between the flexor digitorum superficialis and profundus in the forearm, and enters the hand through the carpal tunnel.

Provides motor innervation to most flexors of the forearm and thenar muscles of the hand. Provides sensory innervation to the lateral palm and palmar surface of the lateral three and a half digits.

임상적 의의

Carpal tunnel syndrome is compression of the median nerve at the wrist, causing numbness, tingling, and weakness. Anterior interosseous syndrome affects motor function. Pronator teres syndrome compresses the nerve proximally. The hand of benediction occurs with high median nerve lesions.
