Question

This response to stimuli is very important in protecting the eyes because although they need light to see, too much light can cause serious damage. Which of the following best describes the nervous system's role in changing pupil size in response to light?

A.
The nervous system works without the aid of other systems in order to provide a sufficiently rapid response.
B.
The nervous system receives and interprets sensory information from the eyes and signals the muscles of the eyes to perform the response.
C.
The nervous system is a network of electrical impulses that becomes activated after the muscles within the eyes perform the response.

Answer 1

The nervous system receives and interprets sensory information from the eyes and signals the muscles of the eyes to perform the response.

Step-by-step explanation:

"The involuntary response of pupils dilating and contracting in response to light involves nerves sending impulses to and from the eyes' light receptors, which in turn tell the muscles in the iris to contract or expand." - Study Island
