In this tutorial, we will draw the motor innervation and sensory coverage of the median nerve. Key structures: brachial plexus, nerve roots, lateral cord, medial cord, anterior interosseous nerve branch, deep forearm muscle group, flexor pollicis longus, flexor digitorum profundus, pronator quadratus, superficial forearm group, flexor digitorum sublimis (also known as flexor digitorum superficialis), pronator teres, flexor carpi radialis, palmar cutaneous sensory branch, carpal tunnel, thenar group, abductor pollicis brevis, opponens pollicis, flexor pollicis brevis, terminal group, lumbricals, primary median sensory coverage, median dorsal continuation.
