The anatomical snuffbox is bordered by the tendons of the extensor pollicis longus and extensor pollicis brevis on the ulnar and radial sides, respectively, and the abductor pollicis longus tendon forms part of its floor. One muscle that does not make up the anatomical snuffbox is the flexor pollicis longus, as it is not involved in the extension of the thumb and lies on the volar side of the forearm. Therefore, while the snuffbox is significant for the tendons involved in thumb extension, the flexor pollicis longus is not part of this structure.
