People are often able to live in a coma for several years because parts of the body that are not under conscious control continue to function. This situation best reflects the importance of the
A) central nervous system
B) autonomic nervous system
C) somatic nervous system
D) forebrain
Answer:
B) autonomic nervous system
Explanation:
The autonomic nervous system is a part of the peripheral nervous system. It comes under the motor division of the peripheral nervous system. The function of this division of the nervous system is to deliver the motor information from the central nervous system to the smooth muscle, cardiac muscle, and glands.  The responses produced by these muscles and glands are not controlled by the will or conscious of the individuals.  
Due to the functioning of the autonomic nervous system, the person under the coma could perform the activities such as breathing, pumping of heart to deliver the oxygen to the body cells, etc. and stay live.
