Median Nerve – The “Labourer’s Nerve”

Let’s Learn about Median nerve..

Root Value:

C5, C6, C7, C8, T1 (brachial plexus-এর lateral এবং medial cords থেকে তৈরি হয়)

Course:

Arm:

Brachial artery-এর lateral দিকে নামে

Mid-arm এ crosses to medial side

Cubital Fossa:

Brachial artery-এর medial side এ থাকে

Forearm:

Between flexor digitorum superficialis & flexor digitorum profundus দিয়ে নামে

Enters the wrist through the carpal tunnel.

Hand:

Supplies thenar muscles এবং lateral 3½ fingers-এর sensation.

Motor Supply:

Forearm:

All flexors except:

Flexor carpi ulnaris (ulnar nerve)

Medial half of FDP (ulnar nerve)

Hand:

Thenar muscles (LOAF):

Lumbricals (lateral 2)

Opponens pollicis

Abductor pollicis brevis

Flexor pollicis brevis

Sensory Supply:

Palmar surface: lateral 3½ fingers + lateral palm

Dorsal surface: fingertips of lateral 3½ fingers

Clinical Importance:

Carpal Tunnel Syndrome:

Compression under flexor retinaculum → tingling, numbness in lateral 3½ fingers, weakness of thenar muscles

Pronator Syndrome:

Compression in forearm

Lesion at elbow (Supracondylar fracture):

Hand of Benediction on making a fist
