U7L1 - Pre Flashcard - Anatomy of the Eye

Front

What is the function of the cornea in the eye?

Back

The cornea helps to focus light as it enters the eye.

Front

What is the aqueous humour?

Back

Aqueous humour is the clear fluid found in the front part of the eye, between the cornea and the lens, which helps maintain intraocular pressure and provides nutrients to the eye.

Front

True or false: The pupil is a physical structure of the eye.

Back

False, the pupil is an opening in the iris, not a physical structure.

Front

What happens to the pupil in bright light conditions?

Back

The pupil contracts to restrict the amount of light entering the eye.

Front

What is the role of the iris in the eye?

Back

The iris controls the size of the pupil and thus the amount of light that enters the eye.

Front

What is the difference between the pupil and the iris?

Back

The iris is the colored part of the eye that surrounds the pupil, which is the opening that allows light to enter.

Front

How does the eye adjust to low light conditions?

Back

In low light conditions, the pupil dilates to allow more light to enter the eye.

Front

What is the vitreous humour?

Back

The vitreous humour is the gel-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eye.

Front

What is the function of the lens in the eye?

Back

The lens focuses light onto the retina, allowing for clear vision.

Front

What is the retina?

Back

The retina is the light-sensitive layer at the back of the eye that converts light into neural signals for the brain.
