What is the significance of the peripheral nervous system? name the component of this nervous system and distinguish between the origin of the two
Answers
The central nervous system is the first nervous system that include the brain and the spinal cord and the second nervous system is the peripheral nervous system which include the nerves in the body that lie outside of the spinal cord and brain. The nerves in peripheral nervous system connects the central nervous system to sensory organs such as the eye and ear and to other organs of the body, muscles, blood vessels and glands.
The components of peripheral nervous system are the somatic nervous system and the autonomic nervous system.
The somatic nervous system is the part of the peripheral nervous system which is the entire nervous system outside of the brain and spinal cord, which associate with voluntary control of body movements via skeletal muscles so somatic nervous system is also known as voluntary nervous system.
The autonomic nervous system is always activated in either symphathetic or parasympathetic state. The division of the autonomic nervous system is known as the enteric nervous system which locate only around the digestive tract. The autonomic nervous system controls the involuntary movements of the body.
Thus, the type of movements controlled by each of them is the main difference between somatic and autonomic nervous system.
Answer:
Explanation:
Peripheral nervous means which include the nerves in the body that lie outside of the spinal cord and brain the nerves in PNS connects the CNS to sensory organs such as eye, nose ,ear. The components are somatic and autonomic nervous system.
Difference:-
Somatic:-
It is a part of PNS which is entire nervous system outside of the brain and spinal cord.
It controls voluntary actions, therefore known as voluntary nervous system...
Autonomic:-
The autonomic nervous system is always activated in either sympathetic or parasympathetic state.It is located around digestive tract..
It controls involuntary movements of the body......
