Parasympathetic nervous system
The parasympathetic nervous system is part of the vegetative or autonomic nervous system. The latter term refers to the fact that this part of the nervous system is not subject to voluntary control. It controls the activities of most of the internal organs as well as the heartbeat. In contrast to its counterpart, the sympathetic nervous system, the parasympathetic nervous system is most active when the body is at rest. Among other things, it controls digestion and urination. Acetylcholine serves as the messenger substance for signal transmission within the parasympathetic nervous system.

Sympathetic nervous system
Part of the autonomic nervous system, whereby the sympathetic nervous system primarily transmits excitatory impulses – in contrast to its counterpart, the parasympathetic nervous system. For example, the sympathetic nervous system activates respiration, the heart, and circulation, but it also affects the smooth muscles of all internal organs. The sympathetic nervous system uses the neurotransmitters acetylcholine and norepinephrine.
