About this quiz
The eye cut through the middle and seen from above. The front of the eye is at the left. The drawing is Ribbia's own, and it shows only parts that can be told apart by shape and position, so every answer is fair.
- Cornea. The transparent front of the eye. It lets light in and, with the lens, focuses it.
- Sclera. The tough white outer coat: five sixths of the eye's surface.
- Choroid. The middle coat, rich in blood vessels, which supplies the eyeball with blood.
- Retina. The innermost coat: the nervous tissue that detects light.
- Iris. The muscle that opens and closes the pupil.
- Pupil. The hole at the centre of the iris that lets light in.
- Lens. Focuses light on the back of the eye; its shape is changed by the ciliary body.
- Ciliary body. The muscular ring attached to the lens, which bends it to focus.
- Aqueous humor. The watery fluid in front of the lens.
- Vitreous humor. The thicker, jelly like fluid that fills the eye behind the lens.
- Optic nerve. Carries the signals from the retina out of the back of the eye to the brain.
