What is the difference between the peripheral and central nervous system?

different systems throughout the body are responsible for different functions. The nervous system is a huge network of organs and nerve paths that together help control all the actions and movements of the body. The entire nervous system can be divided into the peripheral and central nervous system. The central nervous system consists of a brain and a spinal cord and the peripheral nervous system consists of a network of nerve pathways that runs throughout the body. Even reflexes are controlled by nerve impulses. Body movements can be divided into voluntary and involuntary. Most neurons are central neurons. Gli cells are also part of the nervous system and provide structure and support.

The central nervous system consists of brain, spinal cord and cranial nerves, and some experts also include the retina in this category. It is located in the dorsal cavity, which includes the cranial cavity inside the skull and the spinal canal.

The task of the peripheral nervous system is to transmit information to and from the central nervous system. Sensory neurons whoThey carry information to the central nervous system, are called afferent neurons. Motor neurons bear information from the central nervous system and are called eperential neurons.

There are two main parts of the peripheral nervous system: somatic and autonomous systems. The somatic nervous system controls all the functions of the body that are voluntary, such as the protrusion of the tongue or scratching itching. The autonomic system controls all functions that are involuntary, such as breathing and heart rate. It is also part of the autonomic system and is called an enteric system.

The autonomous body system is further divided into parasympathetic and sympathetic systems. The parasympathetic system controls all the functions of the body while it is at rest, such as salivation and urination. The sympathetic system controls all the functions of the body while under the effects of stress. Includes such answers "fighting or flight" such as stopping digestion.
