This 7-part anatomical human eye model shows the optic nerve in its natural position in the bony orbit of the eye (floor and medial wall). At three times life size this eye model is great for anatomical demonstrations. The human eyeball can be dissected into: both halves of sclera with cornea and eye muscle attachments, both halves of the choroid with iris and retina, eye lens and vitreous humour. Now included is the 3B Smart Anatomy app. This app allows users to register their 3B item to extend the warranty plus free 1 year access to the 3B Smart Anatomy app which includes 23 Anatomy lectures, 117 interactive models and 39 quizzes.
