Median Nerve Flashcards
What are the nerve roots of median nerve
C6-T1
What are the motor functions of the median nerve
Flexor muscles in anterior compartment of forearm (except flexor carpi ulnaris and flexor digitorum profundus)
Thenar muscles and lateral two lumbricals
What are the sensory functions of the median nerve
Gives rise to palmar cutaneous branch:-
Innervates later palm
Gives rise to digital cutaneous branch:-
Innervates lateral three and a half fingers on palmar surface of hand
What is the course of the median nerve after originating from brachial plexus in axilla
Descends down arm, lateral to brachial artery
Halfway down arm, crosses over brachial artery medially
Enters anterior compartment of forearm via cubital fossa
Travels between flexor digitorum profundus and flexor digitorum superficialis
Enters hand via carpal tunnel
What branches does the median nerve give off in the forearm
Anterior interosseous nerve
Palmar cutaneous nerve
What does anterior interosseous nerve supply
Deep muscles in anterior forearm
What does palmar cutaneous nerve supply
Skin of lateral palm
What branches does the median nerve terminate into in the hand
Recurrent branch
Palmar digital branch
What does the recurrent branch innervate
Thenar muscles
What does the palmar digital branch innervate
Palmar surface and fingertips of lateral three and a half digits
Innervates lateral two lumbricals
What muscles are supplied by the median nerve
Pronator teres
Flexor carpi radialis
Palmaris longus
Flexor digitorum superficialis
What muscles are supplied by anterior interosseous nerve
Flexor pollicis longus
Pronator quadratus
Lateral half of flexor digitorum profundus
Which branches of the median nerve are responsible for cutaneous innervation
Palmar cutaneous branch
Palmar digital cutaneous branch
