Median nerve
Understand what you see.
Supplies most forearm flexors and selected intrinsic hand muscles plus lateral hand sensation.
Zoom into the original labels. Practise pointing out each structure, then explain it aloud. Diagrams are teaching references; specimen appearance and slide staining vary.
How to recognise it.
- Formed by lateral and medial roots
- Runs with brachial artery in arm
- Traverses carpal tunnel
Point them out.
Tap a number to open its reference, zoom in and locate the structure. Numbers stay the same across views. This key follows landmarks visible in the reference images.

01How do you identify median nerve?+
Formed by lateral and medial roots. Runs with brachial artery in arm. Traverses carpal tunnel.
02Name key forearm exceptions to median supply.+
Flexor carpi ulnaris and the medial part of flexor digitorum profundus are ulnar supplied.
03Why may central palm sensation be spared in carpal tunnel syndrome?+
Palmar cutaneous median branch arises proximal to the tunnel and usually passes superficial to the flexor retinaculum.
04What is its main functional or developmental significance?+
Supplies most forearm flexors and selected intrinsic hand muscles plus lateral hand sensation. Key structures to recognise: Anterior interosseous branch; Recurrent thenar branch; Palmar digital branches.
