Question

I need help. Thank you

Which of the following is an effect of sympathetic activation?
A. constriction of the respiratory passageways
B. change in blood flow and glandular activity associated with sexual arousal
C. stimulation and coordination of defecation
D. stimulation of the medial and lateral pathways associated with a general elevation in muscle tone

Answer 1

The sympathetic nervous system (SNS) is part of the autonomic nervous system (ANS), which also includes the parasympathetic nervous system (PNS). The sympathetic nervous system activates what is often termed the fight or flight response.

Answer 2

Does that clear anything up?

Answer 3

In "fight or flight" you are trying to protect yourself by fighting or running. It is an instinct. That sort f rules out choice B, wouldn't you agree?

Answer 4

Yes I agree with ruling out B

Answer 5

And for C, defecation has to do with getting rid of body waste through poop or feces. So... not quite that one even though some people get scared "ishless" (I don't curse) XD. So not B or C. That leaves A and D.

Answer 6

LOL, I understand your point about C

Answer 7

Haha. Anyways, moving on to choice A. Your heart actually beats faster, and pushes adrenaline through you veins so your lungs work hard to keep up. So constricting the passageway to lungs is not common.

Answer 8

And that leaves us with?....

Answer 9

D
