The anatomy of the human forearm and hand has been described in great detail, including possible anatomical variations. For animals, this information is still not complete. The aim of this case study was to describe the anatomy of the muscles of the forearm and hand in one individual of the Anubis baboon and to compare this information with the available data on the subject and with the anatomical standard and possible variations in humans. The biggest differences were noted in the extensor digiti minimi, where two separate muscle bellies were dissected. We believe that in this individual it was the extensor digiti quarti proprius and extensor digiti quinti proprius muscles. Anatomical standard has not yet been established for the thenar, hypothenar, and contrahentes muscles in the deep layer of the muscles of the forearm of the baboon and literary sources differ notably in some information. Determining the anatomical standard and anatomical variability of individual structures in animals is an important contribution to the field of veterinary surgery and orthopaedics.
