Question

Which branch of the nervous system is most responsible for the contraction of smooth muscle tissue within the human body?

Answers

  1. Central nervous system
    • Rationale:

      The central nervous system is not responsible for the contraction of smooth muscle tissue within the human body.

  2. Somatic nervous system
    • Rationale:

      While the somatic and autonomic nervous systems are sub-branches of the peripheral nervous system, the somatic nervous system is not responsible for the contraction of smooth muscle tissue within the human body.

  3. Peripheral nervous system
    • Rationale:

      While the autonomic nervous system is a branch of the peripheral nervous system, this broad system does not primarily control smooth muscle movements within the body.

  4. Autonomic nervous system
    • Rationale:

      The autonomic nervous system is primarily responsible for the movement of smooth muscles within the human body.

Overview

The nervous system is responsible for the movements of many muscles within the human body.

Explanation

Learning Outcomes

Different branches of the nervous system play different roles regarding muscle movement in the human body. Smooth muscles are controlled by the autonomic nervous system. These muscles are typically found in visceral systems.
