Chapters 14. Autonomic Nervous System (ANS). The ANS consists of . motor neurons. that: . Innervate smooth and cardiac muscle and glands. Make adjustments to ensure optimal support for body activities. The nervous system has 2 major components:. Central Nervous System (CNS). Peripheral Nervous System (PNS).. The CNS. The Central Nervous System includes the brain and the spinal cord. . They are so important to the human body that they are encased in bone for protection.. It influences the function of internal . organs. It acts largely unconsciously. The autonomic nervous system.
