Anatomy of the Eye

Front

What is the function of the cornea in the eye?

Back

The cornea is the transparent front part of the eye that refracts light and helps focus it onto the retina.

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

Define the term 'pupil' in the context of the eye.

Back

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

Front

What is the function of the lens in the eye?

Back

The lens focuses light onto the retina and adjusts its shape to help with focusing on objects at different distances.

Front

What is the retina and its primary function?

Back

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

Front

Explain the role of the optic nerve.

Back

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

Front

What are rods and cones in the retina?

Back

Rods are photoreceptor cells that detect light intensity, while cones are responsible for color vision.

Front

What is the vitreous humor?

Back

The vitreous humor is the gel-like substance that fills the space between the lens and the retina, helping maintain the eye's shape.

Front

Describe the function of the ciliary body.

Back

The ciliary body contains muscles that control the shape of the lens and produce aqueous humor.

Front

What is aqueous humor and its purpose?

Back

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