How the Peripheral Nervous System sense a stimulus and how it is perceived in the central nervous system

Basically , the human body 's nervous system is a group of interconnected tissues , cells , and organs that directs the body 's interaction with its environment , specifically external and internal stimuli reception muscle coordination , behavior regulation , initiation of action , and organ monitoring (New World Encylopedia .org , 2008 . It is mainly divided into two : the central nervous

system and the peripheral nervous system The central nervous system consists of the brain and the spinal cord while the peripheral nervous system consists of sensory neurons , which run from stimulus receptors that notify the central nervous system of the stimuli , and motor neurons , which run from the central nervous system to the glands and muscles in to perform an action (Think Quest .org , 2008 . Basically , both the central nervous system and the peripheral nervous system play essential roles in receiving and interpreting stimuli

In to know how a stimulus is received , it is first necessary to understand the cells and routes involved . Basically , the reception of stimuli begins in the peripheral nervous system which can further be divided into two : the sensory-somatic nervous system , which controls the voluntary body movements using the action of skeletal muscles and external stimuli , and the autonomic or motor nervous system , which controls involuntary functions of the body (Farabee , 2001 .
