Summary Introduction

To describe: The differences between sympathetic and parasympathetic divisions of the autonomic system  with examples of  effect of these systems on specific organs.

Introduction: The central nervous system (CNS) and the peripheral nervous system (PNS) are the two main divisions of a vertebrate’s nervous system. Sensory receptors and nerves make up the peripheral nervous system and are responsible for transmitting information between the CNS and the internal/external environment. The PNS is mainly divided into two divisions, which are the somatic nervous division and the autonomic nervous division. The autonomic nervous division consists of the sympathetic and parasympathetic divisions.
