Please consult the latest official manual style if you have any questions regarding the format accuracy. Why include a review of the autonomic nervous system in a book on pharmacology? The main reason is that autonomic pharmacology is easiest if you have an understanding of the anatomy and physiology of the autonomic nervous system.

16.4 Drugs that Affect the Autonomic System

Evaluation and Management of Autonomic Disorders pp Cite as. Central autonomic network: insular cortex, anterior cingulate cortex, amygdala, hypothalamus, periaqueductal gray matter, parabrachial nucleus, nucleus of the solitary tract, ventrolateral medulla and medullary raphe. Sympathetic pathways: preganglionic sympathetic neurons, prevertebral and paravertebral ganglia. Parasympathetic pathways: cranial and sacral parasympathetic neurons. Specific functional circuits for: blood pressure, heart, thermoregulation, genitourinary, gastrointestinal and effectors of the eyes. Neurotransmission: autonomic ganglia, sympathetic and parasympathetic neurotransmission. Autonomic pharmacology: drugs affecting adrenergic and cholinergic function.

Overview of the Autonomic Nervous System

Differential sympathetic noradrenergic, sympathetic adrenergic, and hypothalamic—pituitary—adrenocortical responses to stressors. Chapter 4. Sensitization of endocrine organs to anterior pituitary hormones by the autonomic nervous system. Chapter 9. Cooling, pain, and other feelings from the body in relation to the autonomic nervous system. Chemotherapy and radiotherapy induced nausea and vomiting: participation of the autonomic nervous system. Chronic electrical stimulation of the carotid baroreflex has sustained effects to suppress sympathetic activity and arterial pressure.


of these key distinguishing features. Physiological Relevance of the. Autonomic Nervous System. The ANS is tightly linked with many behaviors.


Autonomic Nervous System, Volume 117

Widmaier, EP. New York: McGraw-Hill, Learning Objectives After this presentation the learner should be able: To describe the two divisions of the ANS and the main functions and effects of each division. To explain how sympathetic and parasympathetic nerves interact with each other to regulate organ function maintain homeostasis To describe the fight or flight reaction and explain how sympathetic activation affects the activities of the different organs To list the main organ effects caused by parasympathetic stimulation To describe the different autonomic receptors that are stimulated by acetylcholine, norepinephrine, and epinephrine To describe signaling mechanisms and pharmacology of ANS receptor subtypes Marc Imhotep Cray, M.

The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing. Disorders of the autonomic nervous system can affect any body part or process. Autonomic disorders may be reversible or progressive. The autonomic nervous system is the part of the nervous system that supplies the internal organs, including the blood vessels, stomach, intestine, liver, kidneys, bladder, genitals, lungs, pupils, heart, and sweat, salivary, and digestive glands.

The autonomic nervous system ANS , formerly the vegetative nervous system , is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. The autonomic nervous system is regulated by integrated reflexes through the brainstem to the spinal cord and organs. Autonomic functions include control of respiration , cardiac regulation the cardiac control center , vasomotor activity the vasomotor center , and certain reflex actions such as coughing , sneezing , swallowing and vomiting. Those are then subdivided into other areas and are also linked to autonomic subsystems and the peripheral nervous system.

Anatomy, Physiology, and Pharmacology of the Autonomic Nervous System (ANS)

Comprised of the sympathetic nervous system, parasympathetic nervous system, and enteric nervous system, the autonomic nervous system ANS provides the neural control of all parts of the body except for skeletal muscles. The ANS has the major responsibility to ensure that the physiological integrity of cells, tissues, and organs throughout the entire body is maintained homeostasis in the face of perturbations exerted by both the external and internal environments. Many commonly prescribed drugs, over-the-counter drugs, toxins, and toxicants function by altering transmission within the ANS. Autonomic dysfunction is a signature of many neurological diseases or disorders. Despite the physiological relevance of the ANS, most neuroscience textbooks offer very limited coverage of this portion of the nervous system.

This manuscript discusses the physiology of the autonomic nervous system ANS. The following topics are presented: regulation of activity; efferent pathways; sympathetic and parasympathetic divisions; neurotransmitters, their receptors and the termination of their activity; functions of the ANS; and the adrenal medullae. In addition, the application of this material to the practice of pharmacy is of special interest. Two case studies regarding insecticide poisoning and pheochromocytoma are included.
