Summary Introduction
To review:
The part of brain which is the main integration center of the autonomic nervous system and the part that exerts direct influence on autonomic functions.
Introduction:
There are two different parts of nervous system, namely- CNS (central nervous system) and PNS (peripheral nervous system). PNS is comprised of two different divisions which regulates activities of different organs. The two divisions of PNS are ANS (autonomic nervous system) and SNS (somatic nervous system).

What are the functions of the ANS?
Compare the general effects of the sympathetic and parasympathetic divisions of the ANS on mental alertness, metabolic rate, digestive/urinary function, use of energy reserves, respiratory rate, heart rate/blood pressure, and sweat gland activity.
In terms of neurotransmitters and receptors, explain why the two divisions of the ANS can have contrasting effects on the same organs?
