A Challenge Research
The Eye
| Term | Definition |
|---|---|
| aqueous humor | clear fluid filling the space between the lens and the cornea, provides nutrients to both |
| choroid coat | a layer of blood vessels located between the sclera and the retina which absorbs light and limits reflections w/in the eye that could degrade vision |
| ciliary body | tissue that joins the iris to the choroid and produces aqueous humor |
| cornea | transparent membrane in the forepart of the eye, focuses the entry of light into the eye by bending the incoming light onto the lens. |
| iris | colored tissue at the front of the eye that contains the pupil in the center; helps control the size of the pupil to let more or less light into the eye |
| Lens | clear, flexible, convex shaped body, located between the cornea and the vitreous body; enables the changing of focus |
| Optic nerve | bundle of nerve fibers that serves as the communication cable between the eyes and the brain |
| pupil | small opening in the middle of the iris that let in light and focus it on the retina so you can see |
| Retina | contains rods and cones and other nerve cells that receive and organize visual information to send to the brain |
| Sclera | the white portion of the eye that provides protection and form |
| Suspensory ligament | a series of fibers that connect the ciliary body of the eye with the lens, holding it in place |
| Vitreous humor | the clear jelly that fills the eyeball behind the lens. It helps support the shape of the eye and transmits light to the retina. |
