Summary
This document provides an introduction to the sympathetic and parasympathetic nervous systems. These two branches of the autonomic nervous system have opposing effects on the body; the sympathetic system activates the body for action, responding to stress or emergencies, while the parasympathetic system calms the body down by promoting relaxation and energy conservation.

They generally have opposite effects on the body: ### **Sympathetic Nervous System (SNS)** - **Primary Function:** The SNS is often referred to as the "fight or flight" system. It prepares the body to respond to stressful or emergency situations. - **Effects on the Body:** - **Increases heart rate and blood pressure.** - **Dilates pupils** to improve vision. - **Relaxes airways** to improve breathing. - **Inhibits digestion** (decreases activity in the stomach and intestines). - **Releases glucose** from the liver for quick energy. - **Increases blood flow to muscles** while reducing it to non-essential organs. ### **Parasympathetic Nervous System (PNS)** - **Primary Function:** The PNS is often referred to as the "rest and digest" system. It helps the body conserve energy and promotes maintenance activities during calm states. - **Effects on the Body:** - **Decreases heart rate and blood pressure.** - **Constricts pupils.** - **Stimulates digestion** by increasing activity in the stomach and intestines. - **Promotes gland secretion**, such as saliva. - **Conserves energy** by reducing the body's demand for oxygen and nutrients. - **Promotes relaxation** and recovery. ### Summary - **Sympathetic Nervous System:** Activates the body for action, preparing it to handle stressful situations. - **Parasympathetic Nervous System:** Calms the body down, promoting relaxation and conservation of energy. These two systems work in tandem to maintain homeostasis, or balance, in the body's functions.
