What are the peripheral nervous system functions?

6 There are many functions of the peripheral nervous system, all of them serve the general purpose of transmitting information for body processing. This information may come from sources outside or inside the body depending on the position and purpose of any nerve in the system. The human body contains thousands of nerves and each is essential for the smooth functioning of the body.

There are two main functions of the peripheral nervous system, which are processed by two different types of cells called neurons. Sensory neurons record change in the environment and pass it to the central nervous system for analysis. Once the CNS finds out what to do in response to the stimulus, motor neurons make a change. It takes part of a second for this loop to complete, so the body can respond to changes in yourself or in your environment very quickly. Part of PN, which is under voluntary control, is called a somatic nervous system.

some peripheral nerve functionsThe system is automatic. These nerves form an autonomic nervous system and combine internal organs and glands to CNS. They monitor activities such as digestion and secretion of hormones, and are controlled by a firmly regulated feedback system. The heart muscle in the heart is also checked by this system, so it plays a major role in regulating heart rhythm and circulation. Each organ and gland in the body are mostly or completely controlled by the autonomous nervous system, so any problems that arise can have a destructive effect on the body.

The peripheral nervous system can also control inflammation and prepare the body for emergencies. To suppress inflammation, Through signals are sent nerves that suppress chemicals that increase the inflammatory response. Sometimes these signals can completely control inflammation, but in cases that cannot, that does not necessarily mean that something is wrong with the nerves, just that they need help. To prepare the body for emergencies, the PNS triggers a classic reflex "struggle or flight" that increases adrenaline in the blood andincreases heart rate. The peripheral nervous system functions are diverse, but each helps the body in a different situation.
