What is the primary function of the parasympathetic nervous system?

Answer 1

The parasympathetic nervous system (PSNS) is responsible for the stimulation of "rest and digest" or "feed and breed" activities that occur when the body is at rest.

Considered a slowly activated dampening system, the PSNS controls organ and gland functions during rest. Among the bodily functions stimulated by the PSNS are lacrimation, salivation, sexual arousal, urination, digestion, and defecation.

In particular, after the sympathetic nervous system triggers the fight-or-flight response, the PSNS works in tandem with the sympathetic nervous system to restore homeostasis and preserve the body's energy.

The nervous system that controls more routine bodily functions is known as the "feed and breed" system (PSNS). It is essential for maintaining a normal life and without it, routine bodily functions cannot be monitored or regulated. The PSNS also helps to maintain mental and physical health by assisting the body in calming down from stress reactions that raise blood pressure, dilate pupils, and redirect energy from other bodily functions to fighting or running.

One of the autonomic nervous system's three primary divisions is the PSNS.

The primary function of the parasympathetic nervous system is to regulate involuntary bodily functions, such as digestion, urination, and sexual arousal, and to promote relaxation and conservation of energy.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
