Question

for the following descriptive term(s) regarding an aspect of the ans:
most widespread division
select whether it is unique to the parasympathetic or sympathetic systems or belongs to both.
○ both parasympathetic and sympathetic
○ parasympathetic
○ sympathetic

Explanation:

The sympathetic division of the autonomic nervous system (ANS) has a more widespread distribution. It innervates more organs, including those in the skin (like sweat glands, arrector pili muscles) and blood vessels of skeletal muscles, and has a more extensive pre - ganglionic and post - ganglionic fiber distribution compared to the parasympathetic division. The parasympathetic division has a more limited, craniosacral - based distribution, mainly innervating visceral organs in the head, thorax, abdomen, and pelvis, but with less widespread coverage than the sympathetic. So the "most widespread division" refers to the sympathetic division.

Answer:

C. sympathetic (assuming the options are labeled as A. both parasympathetic and sympathetic, B. parasympathetic, C. sympathetic)
