0251-00  Medical Demonstration Skull, 10 parts

More detail than ever before achieved in a plastic skull replica! Cast from a specially prepared natural specimen, this incomparable teaching tool incorporates the following features: the calvaria detaches, then the remainder of the skull divides into halves along the mid-sagittal plane. The perpendicular plate of the ethmoid and vomer is hinged to expose the sphenoid sinus. Highlights of the left half: temporal bone detaches, maxilla is sectioned open revealing the alveolar blood vessels and nerves, frontal bone has a hinged flap into the frontal sinus. Highlights of the right half: temporal bone is partially chiseled away baring the facial nerve canal and the semicircular canals of the inner ear - a hinged flap into the frontal sinus. The detachable mandible is sectioned open on the left side exposing the alveolar blood vessels and nerves. A hinged flap on the right side discloses the roots of the molars and premolars. All 32 teeth are individually removable. Color is used to highlight the sinuses and semicircular canals; to trace cranial nerve tracts and the arteries and meningeal sinuses within the cranium.
