What Is The Peripheral Nervous System?

The peripheral nervous system (PNS) is one of two main parts of the nervous system of the body. The central nervous system (CNS) consists of the brain and spinal cord. The peripheral nervous system branches outside the central nervous system and is composed of nerves and neurons that transmit information to and from the brain. The peripheral nervous system is further divided into two parts called somatic nervous system and the autonomic nervous system.

The peripheral nervous system acts as a connector to the central nervous system. The part of the peripheral nervous system, known as somatic nervous system consists of cranial and spinal nerves. The nerves of the somatic nervous system provide the muscular system and external receptors. And ‘this body part that remains in control to allow the movement. sense of a person to touch, taste, sight, hearing and smell are controlled by the somatic nervous system. In addition, the somatic nervous system is what makes the body feel hot, cold, and pain. It also controls involuntary actions such as blinking.

The second part of the peripheral nervous system is the autonomic nervous system or visceral nervous system. The autonomic nervous system controls and regulates the body internally. The autonomic nervous system is the sympathetic and parasympathetic nervous system. Cranial nerves make up the parasympathetic nervous system. The autonomic nervous system transmits impulses from sensory organs to the brain. This part of the peripheral nervous system is in control when the body is at rest. It ‘also the part of the nervous system that regulates internal processes, such as increased heart rate and reduction as a response to stimuli, the secretion of digestive fluids, and the body’s reaction to stress.

Trauma or injury to the spinal cord or brain can affect both the peripheral nervous system and central nervous system. Disease can also affect the nervous system, and some often present with symptoms affecting the peripheral nervous system. Damage or disease of the central nervous system is often more severe damage to the peripheral nervous system. A neurologist is a doctor who specializes in treating diseases or disorders that affect the nervous system.
