Download or read book Neural Control of Renal Function written by Ulla Kopp and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The kidney is innervated with efferent sympathetic nerve fibers reaching the renal vasculature, the tubules, the juxtaglomerular granular cells, and the renal pelvic wall. The renal sensory nerves are mainly found in the renal pelvic wall. Increases in efferent renal sympathetic nerve activity reduce renal blood flow and urinary sodium excretion by activation of α1-adrenoceptors and increase renin secretion rate by activation of β1-adrenoceptors. In response to normal physiological stimulation, changes in efferent renal sympathetic nerve activity contribute importantly to homeostatic regulation of sodium and water balance. The renal mechanosensory nerves are activated by stretch of the renal pelvic tissue produced by increases in renal pelvic tissue of a magnitude that may occur during increased urine flow rate. Activation of the sensory nerves elicits an inhibitory renorenal reflex response consisting of decreases in efferent renal sympathetic nerve activity leading to natriuresis. Increasing efferent sympathetic nerve activity increases afferent renal nerve activity which, in turn, decreases efferent renal sympathetic nerve activity by activation of the renorenal reflexes. Thus, activation of the afferent renal nerves buffers changes in efferent renal sympathetic nerve activity in the overall goal of maintaining sodium balance. In pathological conditions of sodium retention, impairment of the inhibitory renorenal reflexes contributes to an inappropriately increased efferent renal sympathetic nerve activity in the presence of sodium retention. In states of renal disease or injury, there is a shift from inhibitory to excitatory reflexes originating in the kidney. Studies in essential hypertensive patients have shown that renal denervation results in long-term reduction in arterial pressure, suggesting an important role for the efferent and afferent renal nerves in hypertension.

Available in PDF, EPUB and Kindle. Book excerpt: In the second century, Galen recognized that nerve and muscle were functionally inseparable since contraction of muscle occurred only if the nerves supplying that muscle were intact. He therefore concluded that the shortening of a muscle was controlled by the central nervous sytem while the extension of a muscle could occur in the absence of innervation. Nerves, he thought, were the means of transport for animal spirits to the muscles; the way in which animal spirits may bring about contraction dominated the study of muscle physiology from that time until the historical discovery of Galvani that muscle could be stimulated electrically and that nerve and muscle were themselves a source of electrical energy. It is now well known that nerves conduct electrically and that transmission from nerve to striated muscle is mediated by the chemical which is liberated from nerve terminals onto the muscle membrane. In vertebrates this chemical is acetylcholine (ACh). Thus the concept of spirits that are released from nerves and control muscle contraction directly, is no longer tenable. Nevertheless the concept of 'substances' transported down nerv~s which directly control many aspects of muscle has not been abandoned, and has in fact been frequently reinvoked to account for the long-term regula tion of many characteristics of muscle (see review by Gutmann, 1976) and for the maintenance of its structural integrity.

This book was released on 2018-01-24 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Nerve Control and How to Gain It Selection, expansion, and rearrangement have been made with reference particularly to the prevention, as well as the cure, of the functional nervous troubles so common to day. No book, it should be clearly under stood, can be of more than incidental help to the victim of an organic nervous disease. His chief reliance must always be on the skill of his physician. So, too, as is repeat edly insisted in subsequent -pages, many functionally nervous patients are so condi tioned that expert treatment of a special kind is imperatively needed by them. But of functional nervousness in general it may be said with assurance that much can be done in the way' of self-cure. It is mainly a question of learning to think healthfully and learning to live healthfully. The nervous dyspeptic, the nervous insomniac, all the great army of the nervously run down, are essentially victims of wrong modes of thinking and living. If they can be induced to think and live aright, their ills fall from them. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Neural Control of Gastrointestinal Function written by David Grundy and published by Morgan & Claypool Publishers. This book was released on 2011-12 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gastrointestinal tract is a long, muscular tube responsible for the digestion of food, assimilation of nutrients and elimination of waste. This is achieved by secretion of digestive enzymes and absorption from the intestinal lumen, with different regions playing specific roles in the processing of specific nutrients. These regions come into play sequentially as ingested material is moved along the length of the GI tract by contractions of the muscle layers. In some regions like the oesophagus transit it rapid and measured in seconds while in others like the colon transit is measured in hours and even days, commensurate with the relative slow fermentation that takes place in the large bowel. An hierarchy of controls, neural and endocrine, serve to regulate the various cellular targets that exist in the gut wall. These include muscle cells for contraction and epithelial cells for secretion and absorption. However, there are complex interactions between these digestive mechanisms and other mechanisms that regulate blood flow, immune function, endocrine secretion and food intake. These ensure a fine balance between the ostensibly conflicting tasks of digestion and absorption and protection from potentially harmful ingested materials. They match assimilation of nutrients with hunger and satiety and they ensure that regions of the GI tract that are meters apart work together in a coordinated fashion to match these diverse functions to the digestive needs of the individual. This ebook will provide an overview of the neural mechanisms that control gastrointestinal function.

Download or read book Never Lose Your Nerve written by Alan J Heeger and published by World Scientific. This book was released on 2015-10-09 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Never Lose Your Nerve! chronicles the ups and downs of a Nobel Laureate's life. Professor Alan J Heeger was awarded the Nobel Prize in Chemistry in 2000 together with Professor Alan G MacDiarmid and Professor Hideki Shirakawa. Filled with humor, this book tells Professor Heeger's story — his love for his family, especially how his wife's love has always been his guiding light, his progress from a young student to an eminent scientist, his passion for the theatre and its impact on his science, his adventures as a successful entrepreneur, and his personal losses. Many think of scientists as risk-adverse individuals but Professor Heeger shows the absolute necessity of risk in research and that scientists are, in fact, risk-addicted, as taking the first, risky step into unfamiliar territory is a step in the right direction towards creativity and great discoveries. Never lose your nerve and you will be rewarded. Life is an exciting adventure and this book clearly demonstrates it, and is for those who are looking to impact others.'Perhaps the greatest pleasure of being a scientist is to have an abstract idea, then to do an experiment (more often a series of experiments is required) that demonstrates the idea was correct; that is, Nature actually behaves as conceived in the mind of the scientist. This process is the essence of creativity in science. I have been fortunate to have experienced this intense pleasure many times in my life.'Alan J Heeger
