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.

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 Nerve Muscle Interaction written by Gerta Vrbova and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 246 pages. 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.

Book excerpt: “A compelling story of everyday courage” (Elizabeth Gilbert). Patty Chang Anker grew up eager to please and afraid to fail. But after thirty-nine years, she decided it was time to stop being a chicken. Motivated initially to become a better role model for her two kids, she vowed to master the fears that were choking the fun and spontaneity out of life. She learned to dive into a swimming pool, ride a bike, do a handstand, and surf. As she shared her experiences, she discovered that most people suffer from their own secret terrors—of flying, driving, heights, public speaking, and more. It became her mission to help others do what they thought they couldn’t and to experience the joy and aliveness that is the true reward of becoming brave. Inspired and inspiring, this book draws on Anker’s interviews with teachers, therapists, coaches, and clergy to convey both practical advice and profound wisdom. Through her own journey and the stories of others, she conveys with grace and infectious exhilaration the most vital lesson of all: Fear isn’t the end point to life, but the point of entry.

Download or read book Clinical Assessment of the Autonomic Nervous System written by Satoshi Iwase and published by Springer. This book was released on 2016-09-08 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes newly developed methods of assessing the autonomic nervous system. Up-to-date information on microneurographic analysis of human cardiovascular and thermoregulatory function in humans, heart rate variability, and 131I-metaiodobenzylguanidine (MIBG) scintigraphy are provided. Microneurography, which was originally developed as a technique to analyze the afferent muscle spindle, came to be used to analyze sympathetic nerve activity in the mid-1980s. In the twenty-first century, this technique has become prevalent all over the world especially in investigating the pathophysiology of human cardiovascular function. It is also now used in researching human thermoregulatory function. Heart rate variability is another valuable tool in investigating the current status of human vagal function and in predicting future cardiovascular disease. MIBG is also used to assess cardiac noradrenergic function, especially decreases associated with Parkinson’s disease, Lewy body disease, and multisystem atrophy. Overviews of recent advances in these three important assessments are provided by leading experts.Clinical Assessment of the Autonomic Nervous System is a useful resource for neurologists and researchers of clinical neurophysiology.
