anterior chamber - the front section of the eye's interior where aqueous humor flows in and out of providing nourishment to the eye and surrounding tissues.
blood vessels - tubes that carry blood.
choroid - the thin, blood-rich membrane that covers the white of the eyeball; responsible for supplying blood to the retina.
ciliary body - the part of the eye that produces aqueous humor.
cornea - the clear, dome-shaped surface that covers the front of the eye.
hyaloid canal - narrow passageway that allows blood to flow through the eye.
iris - the colored part of the eye. The iris is partly responsible for regulating the amount of light permitted to enter the eye.
lens (also called crystalline lens) - the transparent structure inside the eye that focuses light rays onto the retina.
macula - the portion of the eye that allows us to see fine details clearly.
optic nerve - a bundle of more than 1 million nerve fibers that connects the retina with the brain. The optic nerve is responsible for interpreting the impulses it receives into images.
posterior chamber - the back section of the eye's interior.
pupil - the dark center in the middle of the iris through which light passes to the back of the eye.
retina - the light-sensitive nerve layer that lines the back of the eye. The retina senses light and creates impulses that are sent through the optic nerve to the brain.
sclera - the white visible portion of the eyeball. The muscles that move the eyeball are attached to the sclera.
suspensory ligament of lens - a series of fibers that connect the ciliary body of the eye with the lens, holding it in place.
vitreous body - a clear, jelly-like substance that fills the center of the eye.
