PPT-ORGANIZATION OF AUTONOMIC NERVOUS SYSTEM

THE AUTONOMIC NERVOUS SYSTEM The autonomic nervous system ANS is a motor or efferent system which connects the central nervous system with all smooth muscle cardiac muscle and gland cells of the body. George Howell III, . Ph.D. Nervous system hierarchy. Enteric Nervous System. Autonomic nervous system. Independent – activities are not under direct conscious control. . (autonomic = automatic). Divided into parasympathetic, sympathetic, and sometimes ENS on an anatomical basis. 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. NERVOUS SYSTEM. LECTURE 12. CH 9 . Neural Control of Involuntary Effectors. The autonomic nervous system helps regulate cardiac, smooth muscle and glands. Impulses are conducted from the CNS to a . second . 15. Autonomic nervous system. is a set of pathways to and from the central nervous system (CNS) that . innervates and regulates smooth muscle, cardiac muscle, and glands. .. •. Autonomic nervous system plays a major role . It influences the function of internal . organs. It acts largely unconsciously. The autonomic nervous system. It . regulates bodily functions such as heart rate, digestion, urination, respiratory rate . The efferent nervous system has two components:. the somatic and . the autonomic. . These two systems differ in a number of ways but are chiefly distinguished by the types of effector organs they innervate and the types of functions they control. . Introduction.
