Human Eye - parts and functions

Front

What is the function of the retina in the human eye?

Back

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

Front

What is the yellow spot (fovea) in the human eye?

Back

The yellow spot, or fovea, is the most sensitive part of the retina, responsible for sharp central vision and color perception.

Front

What is vitreous humour?

Back

Vitreous humour is a transparent, jelly-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eye.

Front

What role does the lens play in the eye?

Back

The lens changes shape to focus light onto the retina, allowing for clear vision at various distances.

Front

What is the optic nerve's function?

Back

The optic nerve carries visual information from the retina to the brain, enabling the perception of images.

Front

What is the purpose of the ciliary muscle in the eye?

Back

The ciliary muscle controls the shape of the lens, allowing the eye to focus on objects at different distances.

Front

What is the function of the iris?

Back

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

Front

What is the aqueous humour?

Back

Aqueous humour is a clear fluid that fills the front part of the eye, providing nutrients to the eye and maintaining intraocular pressure.

Front

What is the sclera?

Back

The sclera is the white outer layer of the eyeball that provides structure and protection to the eye.

Front

What is the conjunctiva?

Back

The conjunctiva is a thin, transparent membrane that covers the front of the eye and lines the eyelids, helping to keep the eye moist.
