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 EMAPA:35287 phalanx distalis Distal-most phalanx within a digit. phalanx distalis SCTID:299711006 UBERON:0004300 middle phalanx distal segment of digit Melissa Haendel Christopher J.
