Our medical study skull shows all the foramina, canals, sutures, and fine details of a real skull. Ideal for advanced study, foramina are bristle patent, making student exploration of perforating cranial nerve branches and blood vessels possible. Comprising the 22 cranial bones (and 28 removable teeth) of our completely disarticulated version, our articulated skull is cradled on a stand, with parietal bones separated, giving access to the interior cranium.
