Special Senses Unit Test

Front

What is the function of the pupils in response to bright light?

Back

The pupils constrict (get smaller) in response to bright light to protect the retina from damage.

Front

Which type of photoreceptor in the eye is responsible for color vision?

Back

Cones are the photoreceptors responsible for detecting all colors of light.

Front

Which special sense is the least developed at birth?

Back

Vision is the least developed special sense at birth.

Front

What structure carries visual messages from the eye to the brain?

Back

The optic nerve carries visual messages to the brain.

Front

What is cerumen and what is its function?

Back

Cerumen, or earwax, is produced by special glands in the auditory canal to protect the ear.

Front

What are rods and what is their primary function?

Back

Rods are photoreceptors in the eye that are responsible for vision in low light conditions.

Front

What is the role of the optic nerve?

Back

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

Front

How do the eyes respond to low light conditions?

Back

In low light conditions, the pupils dilate (get bigger) to allow more light to enter the eye.

Front

What is the difference between rods and cones?

Back

Rods are sensitive to light and allow for vision in dim light, while cones detect color and are responsible for vision in bright light.

Front

What is the function of the auditory nerve?

Back

The auditory nerve carries sound information from the inner ear to the brain.
