part of part of proximally connected to phalanx distal phalanx MA:0002914 terminal phalanx AAO:0010676 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. ungual phalanx uberon EMAPA:35287 phalanx distalis Distal-most phalanx within a digit. phalanx distalis UBERON:0004300 middle phalanx distal segment of digit
