The skeleton of the shoulder of M. unguiculatus is characterized by a large crista epicondyli lateralis humeri and a large foramen supracondylare in the epicondylus medialis. The carpal bones of the 3 animals also have differences. All 3 spp. have 5 digits. In the Mongolian gerbil and in the Syrian hamster each digit consists of 2 parts. The ossa sesamoidea proximales are paired on all digits. M. unguiculatus has, except for the 1st digit, an os sesamoideum distalis on the palmar aspect of the distal interphalangeal joint.
