True or False: Throughout your entire body, the function of acetylcholine is always to inhibit the activity of organs (slow things down), and the function of norepinephrine is to stimulate the activity of organs (speed things up).

Answer: False

Explanation:

Acetylcholine functions in the central nervous system and peripheral nervous system both as activator and inhibitor.

It can cause the skeletal muscle to contract and it also inhibits the activation of the cholinergic system.

Whereas, the norepinehrine functions to mobilize the brain and body for actions. It is released lowest at the the time of sleeping, it shoots up at the time we are awaken and is highest at the time of stress.
