Anatomical Snuff Box

superficial radial nerve

terminal parts of the BLANK pass subcutaneously over the snuffbox as does the origin of the cephalic vein from the dorsal venous arch of the hand

radial artery

the BLANK passes obliquely through the snuff box, deep to the extensor tendons of the thumb and lies adjacent to the scaphoid and trapezium

extensor

the anatomical snuffbox is a term given to the triangular depression formed on the posterolateral side of the wrist and metcarpal 1 by the BLANK tendons passing into the thumb

wrist, thumb

the base of the snuff box is at the BLANK and the apex is directed into the BLANK

schapoid, trapezium, extensor carpi radialis longus, extensor carpi radialis brevis

the floor of the impression is formed by the BLANK and BLANK, and the distal ends of the tendons of the BLANK and BLANK

superficial radial nerve

branches of the BLANK course through the roof of the anatomical snuff box

styloid, thumb

just distal to the BLANK process of the radius at the base of the BLANK, the tendons of abductor pollicis longus, extensor pollicis brevis and extensor pollicis longus form a triangular interval known as the anatomical snuff box
