Question

which part of the autonomic system is most likely to be dominant while someone is napping after lunch?

the peripheral nervous system

the sympathetic nervous system

the somatic nervous system

the parasympathetic nervous system

Explanation:

1. Analyze each option:

• The peripheral nervous system includes both somatic and autonomic systems, so it's not the dominant part here.
• The sympathetic nervous system is for "fight - or - flight" responses, which is active during stress, not rest.
• The somatic nervous system controls voluntary movements, not related to restful states like napping.
• The parasympathetic nervous system is responsible for "rest - and - digest" functions, which is active when the body is at rest, like during a nap after lunch.

Answer:

D. the parasympathetic nervous system
