A120 Giant Classic Eye with Eyelid and Lacrimal System
A120 6 times life-size, this unbreakable plastic replica 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 (tear) 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 functional 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 diagrammatic cross section. 42 hand-coded features are identified in the corresponding key. Mounted on a hardwood base, the model measures 6 X 6 X 6 inches.
