Eye Anatomy final flashcard

Front

What is the function of the retina?

Back

The retina is the light-sensitive layer at the back of the eye that converts light into neural signals, which are sent to the brain for visual recognition.

Front

What is the first eye structure through which light passes?

Back

The cornea is the first structure that light passes through when entering the eye.

Front

What are photoreceptors that detect color called?

Back

Cones are the photoreceptors in the retina that detect color.

Front

What is the blind spot in the eye?

Back

The blind spot is the area of the retina that contains no photoreceptors and is located over the optic nerve.

Front

What is the function of the pupil?

Back

The pupil is the hole in the center of the iris that controls the amount of light entering the eye.

Front

What is the role of the optic nerve?

Back

The optic nerve transmits visual information from the retina to the brain.

Front

What is the difference between rods and cones?

Back

Rods are photoreceptors that detect light intensity and are responsible for night vision, while cones detect color and are responsible for daylight vision.

Front

What is the iris?

Back

The iris is the colored part of the eye that controls the size of the pupil and the amount of light that enters the eye.

Front

What is the aqueous humor?

Back

Aqueous humor is the clear fluid in the front part of the eye that helps maintain intraocular pressure and provides nutrients to the eye.

Front

What is the fovea centralis?

Back

The fovea centralis is a small pit in the retina that provides the clearest vision and is densely packed with cones.
