The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing.

Overview of the Autonomic Nervous System

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 review article provides both historical and current information about the anatomy, physiology, and pharmacology of the sympathetic and parasympathetic divisions of the ANS. The ultimate aim is for this article to be a valuable resource for those interested in learning the basics of these two components of the ANS and to appreciate its importance in both health and disease.

Other resources should be consulted for a thorough understanding of the third division of the ANS, the enteric nervous system.

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. The hypothalamus , just above the brain stem , acts as an integrator for autonomic functions, receiving autonomic regulatory input from the limbic system.

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. ANS vs. The physiologic process of maintaining an internal environment ECF environment compatible w normal health Autonomic reflexes maintain set points and modulate organ system functions via negative feedback in pursuit of homeostasis.

An important way to understand the effects of native neurochemicals in the autonomic system is in considering the effects of pharmaceutical drugs.

Когда он перевернул ее на спину и взгромоздился сверху, она подумала, что сейчас он ее раздавит. Его массивная шея зажала ей рот, и Росио чуть не задохнулась. Боже, поскорей бы все это закончилось, взмолилась она про. - Si. Si! - вскрикивала она в интервалах между его рывками и впивалась ногтями ему в спину, стараясь ускорить его движения.

Глаза Джаббы по-прежнему выражали шок и растерянность, когда сзади раздался душераздирающий крик: - Джабба. Джабба. Это кричала Соши Кута, его технический ассистент, подбегая к платформе с длиннющей распечаткой в руке.

 Думала, кое-кто помоложе? - засмеялся Стратмор. - Да нет, сэр, - попыталась она сгладить неловкость.  - Не в этом дело… - Да в этом.  - Он все еще посмеивался.  - Дэвид Беккер хороший малый.

Беккеру не хотелось так быстро уходить от алтаря, но когда две тысячи людей ждут причастия, а обслуживают их всего восемь священнослужителей, было бы неприличным медлить с этим священным глотком. Чаша была уже совсем близко, когда Халохот заметил человека в пиджаке и брюках разного цвета.

 Сьюзан, - сказал.  - Дай мне двадцать минут, чтобы уничтожить файлы лаборатории систем безопасности. После этого я сразу перейду к своему терминалу и выключу ТРАНСТЕКСТ. - Давайте скорее, - сказала Сьюзан, пытаясь что-нибудь разглядеть сквозь тяжелую стеклянную дверь.
