Cast from nonbreakable vinyl in the same molds as our other giant brains, this student rendition incorporates simplified numbering and a budget-stretching monochrome painting scheme. Component parts are locked together with pins, and will stay together during pass-around until pulled apart. Fifty principal features of the cerebral lobes, cerebellum, brain stem and ventricles are number-coded for identification in the accompanying 3 page key - perfect for introductory study. Supplied without a base. Overall dimensions: Brain anatomy model 8 x 8 x 9 inches (20 x 20 x 23cm).
