Multiple Choice

Which statement describes the parasympathetic division of the autonomic nervous system?

It is responsible for the 'rest and digest' functions.

It increases heart rate and blood pressure.

It primarily uses norepinephrine as its neurotransmitter.

It is activated during the 'fight or flight' response.

Verified step by step guidance

Understand the role of the autonomic nervous system (ANS), which regulates involuntary physiological functions and is divided into the sympathetic and parasympathetic divisions.

Recognize that the parasympathetic division is often described as responsible for 'rest and digest' functions, promoting relaxation and recovery by decreasing heart rate and increasing digestive activities.

Identify that the sympathetic division, in contrast, is associated with the 'fight or flight' response, which increases heart rate and blood pressure to prepare the body for action.

Note that the parasympathetic division primarily uses acetylcholine as its neurotransmitter, whereas the sympathetic division primarily uses norepinephrine.

Conclude that the statement describing the parasympathetic division as responsible for 'rest and digest' functions is correct, as it aligns with its role in promoting bodily maintenance and energy conservation.
