Question

what is nervous system. Write the functions of automatic nervous system ​

Answer 1

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS), where information is evaluated and decisions made.

First, the nervous system collects sensory input from the body and external environment. Second, the nervous system then processes and interprets the sensory input. And finally, the third main function of the nervous system is to respond appropriately to the sensory input.

$\huge\tt\green{Automatic\: nervous\:system}$

The autonomic neural system is involved in involuntary actions like regulation of physiological functions (digestion, respiration, salivation, etc.). It is a self-regulating system which conveys the impulses from the CNS to the smooth muscles and involuntary organs (heart, bladder and pupil).
