	This picture shows the first model of the eye. You should be able to identify the sclera, the cornea, the pupil, and the iris. Click on the picture for the full- size image.
	This picture shows the model of the eye with the outer layer removed. You should be able to identify the choroid, the cornea, the pupil, and the iris. Click on the picture for the full- size image.
	This picture shows the interior of the eye model. You should be able to identify the lens and the vitreous humor. Click on the picture for the full- size image.
	This picture shows the interior of the eye. You should be able to identify the retina and the optic nerve. Click on the picture for the full- size image.
	This model shows the external structures of the eye, along with a number of the external muscles. In this picture you should be able to identify the superior rectus muscle, the inferior oblique muscle, the pupil, iris, cornea, and sclera. Click on the picture to see a larger version.
	In this view, you should be able to identify the superior and lateral rectus muscles. Click the picture to see a larger image.
	This picture shows the preserved eyeball. The cornea is the grayish oval on the front of the eye. The extrinsic muscles are the yellow structures wrapping around the eyeball.
	This image shows the same eyeball from the back - the optic nerve is visible if you squint really hard! :)
	In this picture, the eye has been cut in two, and the back of the eye with the retina is visible. You can also see the optic disk.
	In this picture, the retina has been peeled back to expose the choroid and tapetum lucidum.
	This picture shows the front of the sectioned eye. The vitreous humor is a thick jelly like substance.
	In this picture, the vitreous humor has been removed, and the lens has been pushed to the side to expose the pupil and the ciliary body.
	Here's a drawing you can use to test your knowledge of the parts of the eye. Click on the picture to the right for the full-size image. *Note*: this image lists the names of the parts that you are asked to identify. This is NOT how the lab practicals will work.
