Question

The self governing nervous system is known as-
A. Central nervous system
B. Peripheral nervous system
C. Autonomic nervous system
D. Sympathetic nervous system

Answer 1

Hint: The autonomic nervous system which is a part of the peripheral nervous system, regulates the visceral processes which are needed for maintenance of normal body functions. It operates independently in voluntary control, although certain events, such as stress, sexual excitement, and various other alterations in the sleeping cycle, change the level of the autonomic activity.

Complete answer:
Autonomic nervous system is also known as a self-governing nervous system.
Functions— Autonomic nervous systems generally transmit impulses from the Central nervous system (CNS) to many involuntary organs like the heart. It normally helps a person to deal with emergency situations with the help of 2 divisions namely, Sympathetic division & Parasympathetic division.

(i) Sympathetic division- During the emergency situation, sympathetic division normally helps in quick, powerful & effective actions. It likely stops the digestion of food and causes the flow of blood from our internal organs to the muscles & also increases the breathing rate of a person, oxygen supply, heart rate and sugar level in the blood.
(ii) Parasympathetic division- Parasympathetic division decelerates sympathetic division after the emergency ends. It brings a person heart beat, breathing and blood flow to the normal and controllable levels. It also calms down an individual to the normal condition.

Hence, the correct option is option C i.e autonomic nervous system.

Note: The autonomic system generally is defined as a motor system which innervates 3 major types of tissue like — cardiac muscles, smooth muscles & glands. But, it also relays visceral sensory information to the body 's central nervous system and processes it so that alterations can be done in the activity of specific & autonomic motor outflows, such as those that control the heart and the blood vessels. It also stimulates the release of certain hormones involved in the energy metabolism. For eg- insulin , glucagon and others.
