Question

Which division of the nervous system is the broadest (or most inclusive)?

Answer 1

Well the nervous system divides into the central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) (everything else). From there, the CNS divides into the autonomic (ANS) (reflex functions) and the somatic (SNS) (voluntary movement) nervous systems. The ANS subdivides into the sympathetic (SANS) (fight or flight) and parasympathetic (PSNS) (rest and digest) nervous systems. Not sure exactly what the question is referring to, but this is a basic layout of all of the main nervous systems.

Answer 2

Peripheral

Step-by-step explanation:

The Peripheral Nervous System (PNS) is the longest division of the nervous system and is formed by the nerves and nerve ganglia. Its function is to connect the Central Nervous System to other organs of the body and thereby carry the information transport.

It is one of the divisions of the Nervous System, which is anatomically divided into:

• Central Nervous System (CNS): brain and spinal cord;
• Peripheral Nervous System (PNS): Nerves and nerve ganglia that connect the CNS to the organs of the body.
