How the Body Works: Cross Section of an Eyeball

The eyeball has three major coats-the smooth, protective outer sclera, the middle, pigmented choroid and the inner, light-sensitive retina. In this cross section, the retina and choroid have been peeled away to show the copious blood vessel network under the choroid, which supplies and drains the inner part of the retina as well as the choroid. The focusing mechanism of this involves the ciliary body, the ligaments and the lens.
