Question

The branch of the nervous system that controls everything else is:

a) Autonomic nervous system
b) Central nervous system
c) Peripheral nervous system
d) Somatic nervous system

Answer 1

The branch of the nervous system that controls everything else is the Central Nervous System (CNS), comprising the brain and spinal cord. The correct option is b.

Step-by-step explanation:

It is the control center for the entire nervous system and communicates with the body's peripheral regions through the Peripheral Nervous System (PNS), which consists of the somatic and autonomic nervous systems. The autonomic nervous system is further divided into the sympathetic nervous system, which prepares the body for 'fight-or-flight' responses, and the parasympathetic nervous system, which predominates during restful periods.

The problems of the digestive system are particularly controlled by the parasympathetic nervous system. Hence, b is the correct option.
