What is the peripheral nervous system?

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

The body is associated with the central nervous system through the peripheral nervous system. Part known as the somatic nervous system consists of skull nerves and spinal nerves. The nerves of the somatic nervous system supply the muscle system and external receptors. It is this part of the body that remains under control to allow movement.

The feeling of touch, taste, sight, sound and smell is controlled by a somatic nervous system. This system also causes the body to feel warm, cold and pain. He also controls involuntary actions such as flashing.

The second part is the autonomous nerve synStem or visceral nervous system . The autonomic system controls and regulates the body internally. It consists of sympathetic and parasympathetic nerve systems. Cranial nerves form a parasympathetic nervous system.

The autonomous nervous system transmits the pulses to the az sensory organs to the brain. This system has control when the body is calm. It is also part of the nervous system that regulates internal processes such as increased and reduced heart rate in response to stimuli, secretion of digestive fluids and body response to stress.

trauma or spinal cord or brain damage can affect the peripheral and central nervous system. The 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 serious than damage to peripheral nerves. A neurologist is a doctor whoIt specializes in the treatment of diseases or disorders affecting the nervous system.
