Physiology of the Autonomic 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. The ANS and the accompanying case studies are discussed over 5 lectures and 2 recitation sections during a 2-semester course in Human Physiology. The students are in the first-professional year of the doctor of pharmacy program.
The autonomic nervous system coordinates involuntary control of viscera and other tissues throughout the body, with the exception of skeletal muscle. This branch of the central nervous system, organized into parasympathetic and sympathetic divisions, integrates efferent and afferent fibers that regulate the activities of the majority of organs, glands, and smooth musculature found in the body. The presynaptic cell bodies of neurons composing both categories originate in the gray matter of the spinal column, but are classified by fundamental differences. Anatomically, the origin of the sympathetic thoracolumbar division of the central nervous system lies between the first thoracic T1 and the second or third lumbar section L2 or L3. In contrast, the exiting fibers of the parasympathetic division craniosacral originate from both the medulla oblongata and the sacral portion of the spinal cord S2 to S4. Unable to display preview.

It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric. The sympathetic nervous system SNS and the parasympathetic nervous system PNS contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system CNS.

Like all body systems, the nervous system goes through inevitable age-related changes, including a loss of brain cells, but ageing does not necessarily lead to confusion or dementia. The nervous system controls the activities of all body organs and tissues, receiving input from sensory organs and responding via effector organs. However we do understand, to some degree, how age affects it, as well as the nervous system as a whole. This fifth article in our series on the anatomy and physiology of ageing describes the age-related changes occurring in the brain, spinal cord and peripheral nerves. These changes lead to a gradual decline in cognitive function and a range of other issues, such as reduced bladder control or postural hypotension, but in health the brain normally continues to function adequately throughout life.

The brain and the spinal cord are the central nervous system, and they represent the main organs of the nervous system. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. The regulation of homeostasis is governed by a specialized region in the brain. The coordination of reflexes depends on the integration of sensory and motor pathways in the spinal cord.
Хорошо. Это на нижнем этаже. Возле фреоновых помп. Сьюзан повернулась и направилась к двери, но на полпути оглянулась. - Коммандер, - сказала. - Это еще не конец. Мы еще не проиграли.
Под колесами быстро побежала авеню Луис Монтоно. Слева остался футбольный стадион, впереди не было ни одной машины. Тут он услышал знакомый металлический скрежет и, подняв глаза, увидел такси, спускавшееся вниз по пандусу в сотне метров впереди.
