Answer:
parasympathetic
Step-by-step explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. The nerves that integrate it are born in the brain, forming part of the oculomotor, facial, glossopharyngeal and vagus cranial nerves
Within its functions it controls part of the visual apparatus: When we are nervous or activated, we need to capture all the possible information about the medium or about a particular stimulus, so the pupil dilates. On the contrary, when we are relaxed, the pupil contracts because it is not necessary to capture too much information from the environment, which is also called myosis.
