- 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
