This real human sphenoid bone is a centrally located cranial element that plays a critical role in the structure of the skull. Often described as a “butterfly-shaped” bone, it features broad lateral wings, openings for major nerves and blood vessels, and articulation points with multiple surrounding cranial bones. The specimen displays natural coloration and clear anatomical landmarks, making it ideal for detailed study.

A valuable addition for anatomical education, this specimen is well-suited for classroom demonstration, medical training, or close examination of cranial architecture and bone articulation.

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.
