Quizplus · Accepted Answer

Refraction is the bending of light rays by the media within the eye to focus the image on the retina.

Answer: C
 The lens also plays a role in the refractive process by changing its shape to focus on objects at varying distances.

Answer: K
 The retina is the layer of tissue on the back of the eye that contains light-sensitive cells called photoreceptors.

Answer: L
 The pupil is the opening in the center of the iris that allows light to enter the eye.

Answer: A
 The fundus is the interior surface of the eye opposite the lens and includes the macula, optic disc, and retina.

Answer: B
 The iris is the colored part of the eye that controls the amount of light entering the eye.

Answer: F
 The sclera is the white outer layer of the eye that provides structure and protection.

Answer: G
 The optic disc is the point where the optic nerve exits the back of the eye and there are no photoreceptor cells, resulting in a blind spot.

Answer: H
 The optic nerve is a bundle of nerve fibers that transmit visual information from the retina to the brain.

Answer: I
 The thalamus is a structure in the brain that serves as a relay station for sensory information, including visual information from the optic nerve.

Answer: D
 The macula is the part of the retina responsible for sharp, detailed vision. It contains a high concentration of photoreceptor cells called cones.

Answer: E
 The optic chiasm is the point where the optic nerves from each eye cross over, allowing information from both eyes to be processed in the visual cortex of the brain.
