In human anatomy, the distal phalanges of the four fingers and toes articulate proximally with the intermediate phalanges at the distal interphalangeal joints (DIP); in the thumb and big toe, with only two phalanges, the distal phalanges articulate proximally with the proximal phalanges. The distal phalanges carry and shape nails and claws and are therefore occasionally referred to as the ungual phalanges. The distal phalanges are cone-shaped in most mammals, including most primates, but relatively wide and flat in humans.
