- Discussion:
- palmar cutaneous branch of
median nerve arises from radial border of median nerve approximately
5 to 6 cm proximal to distal transverse flexion crease of the wrist;
- it runs along the
median nerve for 2 to 3 cm, and then runs along the
ulnar border of the
flexor carpi radialis tendon;
- in some cases it may run along the ulnar side of the
palmaris longus tendon;
- when the tendon enters the flexor retinaculum comparment, the nerve passes between the two layers of
the forearm fascia into the root of the palmar aponeurosis;
- after 5-10 mm, the nerve divides into three terminal branches which cross the midpalmar aponeurosis to supply
deep layers of dermis;
