Question

The opening in the iris through which light passes is the
A) conjunctiva.
B) cornea.
C) pupil.
D) anterior chamber.
E) posterior chamber.

Accepted Answer

The pupil is the opening in the iris through which light passes. The conjunctiva is a thin, transparent membrane that covers the sclera (white part of the eye) and the inside of the eyelids. The cornea is the clear, dome-shaped surface that covers the front of the eye. The anterior chamber is the fluid-filled space between the cornea and the iris, and the posterior chamber is the fluid-filled space behind the iris but in front of the lens. Neither of these chambers is the opening through which light passes.
