Distinguish between the central nervous system and the peripheral nervous system.?

Question

What are the two subdivision of the peripheral nervous system and what do these divisions do?

Answer 1

central nervous system is composed of the brain and spinal chord. It contains the interneurons that relay chemical messages from afferent neurons to efferent neurons, which are both in the peripheral nervous system.

Peripheral nervous system is made of sympathetic and parasympathetic nervous systems.

Answer 2

The central nervous system (CNS) represents the largest part of the nervous system, including the brain and the spinal cord. Together with the peripheral nervous system, it has a fundamental role in the control of behavior. The CNS is contained within the dorsal cavity, with the brain within the cranial subcavity, and the spinal cord in the spinal cavity.

The peripheral nervous system or PNS, is part of the nervous system, and consists of the nerves and neurons that reside or extend outside the central nervous system (the brain and spinal cord) to serve the limbs and organs, for example.

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system.

The somatic nervous system is associated with the voluntary control of body movements through the action of skeletal muscles, and also reception of external stimuli. The somatic nervous system consists of afferent fibers that receive information from external sources, and efferent fibers that are responsible for muscle contraction.

The autonomic nervous system controls homeostasis, that is the constancy of the content of tissues in gasses, ions and nutrients. It does so mostly by controlling cardiovascular, digestive and respiratory functions, but also salivation, perspiration, diameter of the pupils, micturition - (the discharge of urine), and erection. Many of the activities of the ANS are involuntary

Answer 3

The central nervous system is the brain and spinal cord. The peripheral nervous system is the nerves which innervate the rest of the body.

That should also answer the second part...

Answer 4

The central nervous system
Is the brain and the spine.
The brain controls the system
And the spine is the line.
Telegrams come in
To tell what's happening to you,
Then telegrams go out
To tell your body what to do.

Your peripheral nerves,
They go all out,
Delivering those messages
Your senses send out.
From your hearing and touch
To your sight and taste and smell,
They let your brain react
To all the messages they tell.
