Answer 2

Question:

Which of these activities is most likely driven by parasympathetic innervation?

A) Sweating and dilating pupils

B) Resting and digesting

C) Fight-or-flight responses

D) Vigorous physical activity

Answer:

The correct answer is B) Resting and digesting

Step-by-step explanation:

Remember that the Somatic Nervous System is that part of the nervous system that voluntarily responds to external stimuli while the Autonomic Nervous System involuntarily regulates internal body functions.

Please note that the Autonomic Nervous System is further subdivided into two: the Sympathetic Nervous System and the Parasympathetic Nervous System.

Parasympathetic fibers are primarily in the vagus nerves, but some that regulate sub-diaphragmatic organs travel through the spinal cord.

The parasympathetic division, sometimes called the "rest and digest" system, keeps body energy use as minimal as possible, even as it controls important bodily functions like breaking-down food for absorption and eliminating excrement and urine.
