All of the following are primarily controlled by the autonomic nervous system except one. Which of the following is not primarily controlled by the autonomic nervous system?
  1. Peristaltic contractions of certain digestive organs
  2. Production of tears by the tear glands
  3. Tongue movement during eating
  4. Dilation or constriction of blood vessels
  5. Salivary and digestive gland secretions
Explanation
Answer - C - All of the choices above are controlled primarily by the autonomic nervous system except tongue movement during eating, which is under a person’s voluntary control. The autonomic nervous system controls involuntary functions primarily. The central nervous system processes information coming in from the sensory organs via sensory neurons of the peripheral nervous system. The central nervous system then controls the voluntary muscles of the body via motor neurons of the peripheral nervous system.
