The anatomical snuffbox is a term commonly used to described a triangular
depression on the lateral side of the wrist
that is bounded medially by the tendon of
extensor pollicis longus and laterally by the tendons of abductor pollicis
longus and extensor pollicis brevis. Its clinical importance lies in the
fact that the scaphoid bone is most easily palpated here and that the pulsations
of the radial artery can be felt.
