the nervous system is involved in receiving information about the receiving information about the environment around us ( sensation) and generating responses to that information ( motor responses). the nervous system can be divided into regions (sensory functions) and for the response ( motor functions)

central nervous system: the structures of the cns are the brain and spinal cord. their job is to integrate information coming back from the peripheral nervous system and to respond automatically or make decisions on actions that should be taken. you can think of the cns as the head office of the body it wors consciously and subconsciously to control all activities within the body. 
peripheral nervous system ( pns) the structures of the pns include the cranical nerves ( nerves of the head) and spinal nerves
their job is to communicate information between the cns and the rest of the body
SENSORY (AFFERENT) DIVISION 
The sensory (also known as afferent) division of the nervous system contains nerves that come from the viscera ( internal organs) and the somatic areas ( muscles, tendons, ligaments, ears, eyes, and skin) 
these nerves conduct impulses to the pns/ cns providing information on what is happening within and outside the body. the senses include, hearing, sight, touch, and proprioception ( the awareness of where you are in space and what position you re in)
MOTOR ( EFFERENT) DIVISION
the motor ( also know as efferent)  division of the nervous system contains motor nerves.
these nerves conduct impulses from the cns and pns to the muscles, organs and glands effecting what happens in those tissues.
SOMATIC NERVOUS SYSTEM.
the somatic division of the nervous system contains nerves which end in the skeletal muscles.
These nerves conduct impulses which control the skeletal muscles in response to a directive that comes from the brain, this conscious control means we call the activity of this division voluntary.
SYMPATHETIC DIVISION
The sympathetic division of the nervous system is part of the autonomic nervous system. it works automatically to mobilise the body's systems during activity (for example the fight or flight response)
if you have ever had a fright and afterward realise your heart is still beating rapidly, you have experienced the activity of the sympathetic portion of the autonomic nervous system.
PARASYMPATHETIC DIVISION
the parasympathetic division of the nervous system is part of the autonomic nervous system as well. it works automatically' functions when the body system. it promotes digestion and other housekeeping functions when the body is at rest. the following diagram highlights how the sympathetic and parasympathetic divisions have diffrent effcts on various organs.
