Question

Quizplus · Accepted Answer

The iris is responsible for changing the size of the pupil, which determines the amount of light that enters the eye.

Answer: A
 The aqueous humor is a clear fluid that maintains pressure within the eye.

Answer: B
 The choroid is a layer of tissue that provides nutrients to the retina and absorbs excess light.

Answer: D
 The cornea is the clear outermost layer of the eye that helps to focus incoming light.

Answer: E
 The fovea centralis is an area in the center of the retina that contains a high concentration of cones and is responsible for sharp, detailed vision.

Answer: H
 The retina is a layer of tissue at the back of the eye that contains photoreceptors (rods and cones) that convert light into electrical signals.

Answer: I
 Rods are photoreceptor cells in the retina that are sensitive to low levels of light and are important for night vision.

Answer: J
 The vitreous humor is a clear gel-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eyeball.

Answer: G
 The optic disc, also known as the blind spot, is a circular area on the retina where the optic nerve exits the eye, and as a result, there are no photoreceptor cells in this area.
