Answer» Correct Answer - B The wall of each eyeball is made up of three concentric layer-sclerotic, choroid and retina. The choriod is a highly vascular pigmented layer separating the the sclerotic from the inner layer of the eyeball. It is connected in front to a thick structrure called cillary body. Iris is a pigmented, muscular, opaque diaphragm which extends from the cillary body in front of a biconvex trasnparent lens, iris has a small central biconvex trasnparent lens. iris has a small central aperture called pupil. Light passing through the comes enters through the pupil to fall on the lens behind it. The iris has two sets of smooth muscles arranged circularly and radially around the pupil. the pupil get of circular msucles to reduce the amount of light falling on the lens. on the contrary. the pupil gets dilated by the contraction of radial muscles to increase the amount of light falling on the lens.
