0102-00 Giant 5 part Eyeball
Six-times life-size, this unbreakable vinyl 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 extrinsic muscles of the eye, the optic nerve roots, and surrounding blood vessels.
The eyeball divides in half for study of the interior including the meticulously hand-painted choroid coat of the retina. Here, several removable parts are discovered such as the vitreous ball, iris/cornea, and Lucite lens, capable of magnifying and inverting images when removed from the model. 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. The model measures 6x6x6 inches (15x15x15 cm).
0133-00 Giant Three-Part Ear
Dwarfs ordinary ear models and demonstrates equilibrium with liquid-filled canals. 5 times life-size, this unbreakable polymer reproduction depicts the human organ of hearing and balance. Sagittally sectioned along the length of the auditory canal and Eustachian tube, it is easy to trace the path of sound waves entering the ear, and it becomes clear how pressure is equalized on both sides of the eardrum. The entire middle ear chamber and the labyrinth is exposed to view. The malleus (hammer) and incus (anvil), and the attached see-through tympanic membrane lift out, as well as the entire labyrinth unit, for hands-on study. Two of the three semicircular canals are made of transparent tubing filled with colored fluid representing the endolymph. An air bubble in each will shift position when tilted, demonstrating the function of the canals in maintaining equilibrium. A spiral cutaway of the cochlea shows its three canals in contrasting colors to teach the concept of pitch. 36 hand-numbered features are identified in the accompanying key. 16x11x7 inches (41x28x18 cm).
0179-00 Base of Head and Seven-Part Brain
Portraying the base of the human head, this life-size nonbreakable replica features a detailed brain, complete with arterial blood vessels, including the basilar artery and Circle of Willis, cranial nerves, and dissectible brain stem.
The entire brain can be lifted from the cranial vault and separated in seven parts. The right cerebral hemisphere divides along its length following the border of the corpus callosum, while the left can be split to expose the posterior horn of the lateral ventricle and hippocampus. Dissections of the cranial floor expose the eyeball, its muscles, lacrimal gland, optic nerve, and the middle and inner ear. 107 hand numbered features are identified in the accompanying key.
Overall dimensions: 8x9x6 inches (17x22x15cm).
