Your body is truly amazing - in this book find out what's going on under your skin from your skeleton that is the frame of your body to the muscles that move your bones. The book is perfect for children aged 7+ who are studying science and the human body. The book is part of the series 'Your body - inside and out' in which photographs and artwork combine to show you how your body works - both inside and out
The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

See the body's bones, joints, and muscles in action! Highly visual and in full color, Kinesiology: The Skeletal System and Muscle Function makes it easy to understand kinesiology concepts and how they would be applied to the treatment of dysfunction. It contains over 1,200 illustrations, including a bone atlas that shows every bone in the human body and six chapters with detailed, illustrated coverage of joints. Written by noted educator and author Joseph E. Muscolino, this book clearly depicts how muscles function as movers, antagonists, and stabilizers. This edition expands its reach to athletic training with two new chapters on stretching and strengthening exercises. This title includes additional digital media when purchased in print format. For this digital book edition, media content may not be included Companion DVD includes over one hour of video demonstrating all the major joint actions of the human body, with a voiceover explanation of the names of the motions, the planes in which motion occurs, and the axes around which motion occurs. Unique! A focus on the needs of massage therapists and bodyworkers makes it easier to apply kinesiology concepts to the practice of massage therapy. Unique! A complete bone atlas includes over 100 full-color photographs showing every bone in the human body. 1,200 full-color illustrations help you understand concepts relating to the bones of the human body, joints of the human body, and muscle function parts. A logical, easy-to-reference format moves from basics (like parts of the body) to more difficult topics (such as microphysiology). Six chapters on joints cover structure, function, and terminology, with specific illustrations on each joint in the human body: joints of the axial body, joints of the upper extremity, and joints of the lower extremity. Student-friendly features in each chapter include an outline, learning objectives, overview, key terms with pronunciations, and word origins designating the Latin or Greek derivative. Clear, simple explanations make it easy to understand kinesiology concepts, including muscle contraction(s), coordination of muscles with movement, core stabilization, posture, exercise, reflexes, and how the nervous system controls and directs the muscular system. Expert author Joseph E. Muscolino, DC, offers years of experience in the study of muscles and muscle function, as well as bodywork and massage, and conveys that information in an understandable format.
The extremely potent substance botulinum neurotoxin (BoNT) has attracted much interest in diverse fields. Originally identified as cause for the rare but deadly disease botulism, military and terrorist intended to misuse this sophisticated molecule as biological weapon. This caused its classification as select agent category A by the Centers for Diseases Control and Prevention and the listing in the Biological and Toxin Weapons Convention. Later, the civilian use of BoNT as long acting peripheral muscle relaxant has turned this molecule into an indispensable pharmaceutical world wide with annual revenues >$1.5 billion. Also basic scientists value the botulinum neurotoxin as molecular tool for dissecting mechanisms of exocytosis. This book will cover the most recent molecular details of botulinum neurotoxin, its mechanism of action as well as its detection and application.
The Social Security Administration (SSA) administers two programs that provide disability benefits: the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. SSDI provides disability benefits to people (under the full retirement age) who are no longer able to work because of a disabling medical condition. SSI provides income assistance for disabled, blind, and aged people who have limited income and resources regardless of their prior participation in the labor force. Both programs share a common disability determination process administered by SSA and state agencies as well as a common definition of disability for adults: "the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months." Disabled workers might receive either SSDI benefits or SSI payments, or both, depending on their recent work history and current income and assets. Disabled workers might also receive benefits from other public programs such as workers' compensation, which insures against work-related illness or injuries occurring on the job, but those other programs have their own definitions and eligibility criteria. Selected Health Conditions and Likelihood of Improvement with Treatment identifies and defines the professionally accepted, standard measurements of outcomes improvement for medical conditions. This report also identifies specific, long-lasting medical conditions for adults in the categories of mental health disorders, cancers, and musculoskeletal disorders. Specifically, these conditions are disabling for a length of time, but typically don't result in permanently disabling limitations; are responsive to treatment; and after a specific length of time of treatment, improve to the point at which the conditions are no longer disabling.
