This document provides an overview of the autonomic nervous system (ANS). It describes that the ANS consists of motor neurons that innervate smooth and cardiac muscle and glands to make adjustments and ensure optimal body support through subconscious control. The ANS differs from the somatic nervous system in its effectors, efferent pathways, and target organ responses. The ANS is divided into the sympathetic and parasympathetic divisions which counterbalance each other. The sympathetic division is involved in the fight or flight response while the parasympathetic performs maintenance functions.
It includes the basic anatomy physiology of skeletal muscles, the thorough working of the muscles, at superficial level to molecular level, the energy input, smooth muscle-cardiac-skeletal muscles differences, smooth muscle anatomy physiology.

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
