Does autonomic nerve belong to peripheral nervous system?

summary

Autonomic nervous system is the peripheral nervous system of vertebrates, which is differentiated and developed from somatic nerves to form a functional independent nervous system. It is composed of single or mainly efferent nerves, which are dominated by the brain, but it has more independence, especially with autonomous activities not dominated by the will. Does the autonomic nerve belong to the peripheral nervous system? Next, I'd like to share my views with you.

Does autonomic nerve belong to peripheral nervous system?

Autonomic nervous system is a part of peripheral efferent nervous system, which can regulate the activities of visceral and vascular smooth muscle, myocardium and glands. Also known as autonomic nervous system, not random nervous system. As the visceral reflex is usually not freely controlled, it is called autonomic nervous system. Autonomic nervous system is composed of sympathetic nervous system and parasympathetic nervous system,

It controls and regulates the activities and secretion of various organs, blood vessels, smooth muscles and glands, and participates in endocrine regulation of glucose, fat, water and electrolyte metabolism, as well as body temperature, sleep and blood pressure. Under the control of cerebral cortex and hypothalamus, the two subsystems can regulate the physiological activities of organs both antagonistically and coordinately. The structure of autonomic nervous system can be divided into central part and peripheral part.

Autonomic nervous system is mainly distributed in viscera, cardiovascular system and gland. The central part of autonomic nervous system is also in brain and spinal cord. The peripheral part includes visceral motor (efferent) fiber and visceral sensory (afferent) fiber, which constitute visceral motor nerve and visceral sensory nerve respectively.
