Question

Which is a division of the autonomic nervous system (ANS)?

Answers

  1. Central nervous system
    • Rationale:

      The central nervous system is a primary branch of the nervous system that includes the brain and the spinal cord. It is not a division of the ANS.

  2. Peripheral nervous system
    • Rationale:

      The peripheral nervous system is a primary branch of the nervous system that is further divided into the somatic and autonomic nervous systems. It is not a division of the ANS.

  3. Sympathetic nervous system
    • Rationale:

      The sympathetic nervous system is a branch of the ANS. It is responsible for the body’s digest-and-response responses.

  4. Somatic motor nervous system
    • Rationale:

      The somatic nervous system is a branch of the peripheral nervous system, not the ANS.

Overview

The nervous system is the network of nerve cells and fibers that transmit nerve impulses between parts of the body.

Explanation

Learning Outcomes

The autonomic nervous system is a branch of the peripheral nervous system. It has two individual branches of its own: the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system activates the body’s fight or flight response.

Test Taking Tip

Consider the branches, or divisions, of the nervous system when determining the correct choice for this question.
