[WP,modified]. Wikipedia:Cuboid_bone NCIT:C32414 UBERON:0001455 EMAPA:36175 NominaAnatomicaVeterinaria uses os cuboideum as an official synonym for distal tarsal IV, but some sources also use this as the label for the human cuboid bone which is regarded to be formed from tarsals IV and V. We therefore decline to use exact syns in either case.
