Which of the following is one of the two main divisions of the nervous system?

The peripheral nervous system is indeed one of the two main divisions of the nervous system, alongside the central nervous system. The peripheral nervous system encompasses all the nerves and ganglia outside the brain and spinal cord, playing a crucial role in connecting the central nervous system to limbs and organs. It is responsible for transmitting sensory and motor information to and from the central nervous system, allowing the brain to communicate with the body and vice versa.

The other options, while related to the overall functioning of the nervous system, refer to specific components or systems within these divisions. The somatic nervous system is a component of the peripheral nervous system that specifically controls voluntary movements and sensory information from external stimuli. The autonomic nervous system, also a part of the peripheral nervous system, regulates involuntary physiological functions such as heart rate and digestion. The term "centrifugal nervous system" is not a recognized division of the nervous system, further confirming that peripheral nervous system is the correct choice here.
