Explanation The sympathetic division of the autonomic nervous system influences the body in distinct ways by increasing the brain’s alertness, increased heartbeat rate, glucose release unto the blood stream, and so on. This is initiated by sudden stimuli of individual’s situation and so is termed as fight-or-flight response. Sympathetic nervous system innervates both the central and peripheral nervous systems. It starts right from the nuclei of the brainstem after the spinal cord and peripheral ganglia and to the target organ site. Usually, the sympathetic systems emerge by the short preganglionic nerve fiber from the brainstem or from the spinal cord. These preganglionic nerve fibers are myelinated, and its synapses connect with the dendrites ganglionic nerve of the terminal nodal ganglion in the spinal cord...

Summary Introduction

Introduction:

Sympathetic nervous system is part of the autonomic nervous system, which is responsible for governing most of the vital body functions. Sympathetic division consists of preganglionic and postganglionic nerve fibers as their integral constituents to perform its action in the target organ site. Since the sympathetic system emerges from the brain and it innervates a large group of organ sites, it has a long network of preganglionic and postganglionic nerve fibers associated with them through spinal cord.
