Muscular System

"With more than 700 illustrations and a new full-color design, this manual presents all of the body's muscles in an easy-to-understand format. Its molecular approach lets you choose the level of depth you need - from simply the basics to the most advanced level." - back cover.

The muscular system is made up of three different kinds of muscles: skeletal muscles, smooth muscle, and heart muscle. But what does each kind of muscle do? And where in the body are they located? Explore the muscular system in this engaging and informative book.

This is an integrated textbook on the musculoskeletal system, covering the anatomy, physiology and biochemistry of the system, all presented in a clinically relevant context appropriate for the first two years of the medical student course. One of the seven volumes in the Systems of the Body series. Concise text covers the core anatomy, physiology and biochemistry in an integrated manner as required by system- and problem-based medical courses. The basic science is presented in the clinical context in a way appropriate for the early part of the medical course. There is a linked website providing self-assessment material ideal for examination preparation.

Don't move a muscle--read all about them! Did you know that... Without muscles you couldn't blink--or even breathe! Nearly 700 muscles control your life. Big or small, a muscle is made up of just one cell. Exercise doesn't give you more muscles, but it strengthens the ones you have. Discover how muscles make us move--and see what it really looks like under your skin.

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.

Based on Bodynamic Analysis, a body-oriented psychology developed in Denmark by the authors and their colleagues, Body Encyclopedia describes the developmental sequence in which psychological and emotional elements are linked to specific muscles. The book shows how certain responses to events in our lives end up bound and connected with our movement patterns. Through extensive research, Marcher, Fich, and several others have mapped out the psychological functions of 154 muscles and related tissues. Featuring more than 200 detailed illustrations, Body Encyclopedia opens with an introduction to the history and development of Bodynamic Analysis. The core of the book presents a description of each muscle, including movement positions, age level when the muscle is activated, and a summary of the psychological themes associated with each muscle. Basic instructions are provided for bodymapping, a hands-on procedure that involves palpating and registering muscle response. Vivid case studies demonstrate how to apply the information in real-life situations. Using the book as a guide, readers can accurately identify and investigate the underlying psychological issues associated with muscle pain, discomfort, or weakness in specific areas of the body.
