Peripheral Nervous System Divisions And Functions, Nervous System Organization

The nervous system is a vital organ system of our body that comprises a set of.

Hinge joint type. The autonomic nervous system provides unconscious control over visceral functions and has two divisions. This system is responsible for sending receiving and interpreting information from all parts of the body. The nervous system of vertebrates including humans is divided into the central nervous system cns and the peripheral nervous system pns.

The key difference between central and peripheral nervous system is that the central nervous system includes the brain and the spinal cord while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. The peripheral nervous system contains both the autonomic and sensory somatic nervous systems. In this article we will discuss the peripheral nervous system its divisions and its functions.

This system can be divided into two parts. The nervous system is divided into the central nervous system and peripheral nervous system. Overview of peripheral nervous system.

The spinal canal contains the spinal cord while the cranial cavity contains the brain. The sympathetic and parasympathetic nervous systems. To learn how the nervous system functions you must learn how the nervous system is put together.

The central nervous system cns consists of the brain and spinal cord leaving everything else in the peripheral nervous system pns. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. The nervous system can be divided into several connected systems that function together.

The peripheral nervous system pns is one of two components that make up the nervous system of bilateral animals with the other part being the central nervous system cns. Nervous system anterior view in this article well discuss the peripheral nervous system and its divisions as well as the peripheral nervesthe peripheral nervous system pns consists of all the nerves branching out of the brain and spinal cord the central nervous system cnsif you imagine the cns as the main highway then the pns forms all the connecting secondary roads. The cns is enclosed and protected by the meninges a three layered system of.

There is a lot to learn about the nervous system and the pathologies associated with it. The pns consists of the nerves and ganglia outside the brain and spinal cord. What we do know is that there are two nervous systems in the human.

The main function of the pns is to connect the cns to the limbs and organs essentially serving as a relay between the brain and spinal cord. It operates independently of voluntary control although certain events such as stress fear sexual excitement and. The central nervous system cns and the peripheral nervous system pns.

Lets start with a simple division. The autonomic nervous system is the part of the peripheral nervous system that regulates the basic visceral processes needed for the maintenance of normal bodily functions.
