This real human upper limb specimen includes the humerus, radius, and ulna, with hand-painted muscle attachment labels to support detailed anatomical study. Clearly marked structures—such as the deltoid region, supinator, and forearm muscle groups—provide a visual guide to muscle origins and insertions along the bones.

We believe education is the greatest gift osteology can share and that every human specimen can contribute to the advancement of science. These specimens are provided to us by retired physicians, medical researchers, dental professionals, and former university medical programs. We also work with accredited donor programs. A small sample - often antiques that simply do not qualify for medical/research grade usage - are made available to osteology enthusiasts worldwide so that they may continue to educate and inform.
