Question

define retina??????????​

Answer 1

Answer:

Retina: The retina is the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain. There is a small area, called the macula, in the retina that contains special light-sensitive cells. The macula allows us to see fine details clearly.

The eye has a number of other components. These include the cornea, iris, pupil, lens, optic nerve and vitreous.

The cornea is the clear front window of the eye that transmits and focuses light into the eye.

The iris is the colored part of the eye that helps regulate the amount of light that enters the eye.

Answer 2

Answer:

The retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve. The purpose of the retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
