5-Part Functional Eye
    Six times life-size unbreakable vinyl plastic replica of the eye is packed with useful teaching features.  On the exterior of the eyeball is the cornea, through which the iris and pupil are visible.  The large lacrimal (rear) gland, attachments for all six muscles that move the eyeball, the optic nerve, and surrounding blood vessels.  The eyeball divides in half to study the interior.   The iris / cornea can be removed as can the functioning Lucite lens, which magnifies and forms inverted images.  The transparent vitreous body exposes the choroid coat and retina.  Rods, cones and other retinal microstructures are detailed in a highly magnified diagramatic cross section.  42 hand-coded features are identified in the corresponding key.  Mounted on  a hand-rubbed hardwood base, the model measure 6 x 6 x 6 inches.
