The muscle system is responsible for movement of the human body, posture, movement of substances inside the body andfor the generation of body heat. There are approximately known and named muscles and on top of that, muscle tissue is also found inside of the heart, digestive organs, and blood vessels. Skeletal muscle is a voluntary muscle, which means that we can actively control its function. Skeletal muscles often exist in pairs, whereby one muscle is the primary mover and the other acts as an antagonist. For example when you bend your arm, your biceps contracts whilst your triceps is relaxed.
All muscle cells share several properties: contractility, excitability, extensibility, and elasticity:. Maintenance of posture: Without much conscious control, our muscles generate a constant contractile force that allows us to maintain an erect or seated position, or posture. Respiration: Our muscular system automatically drives movement of air into and out of our body. Heat generation: Contraction of muscle tissue generates heat, which is essential for maintenance of temperature homeostasis. For instance, if our core body temperature falls, we shiver to generate more heat.
Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body. The human body contains three different kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart. In this article, we discuss the structure and function of cardiac muscle tissue. We also cover medical conditions that can affect cardiac muscle tissue and tips for keeping it healthy.
The Structure and Function of Muscle discusses relevant issues that directly affect both the structure and function of the muscular system. These issues are approached from different perspectives, such as biochemical and molecular. This book discusses several factors that can affect the condition and performance of the muscular system, both externally parasitic and viral infections, nutritional deficiency, drugs and internally genetics and muscular degeneration. It also presents several types of myopathies and their distinctive traits compared to other diseases with similar symptoms. This text contains relevant information about the causes and effects of the afflictions of the muscular system. Students, medical practitioners, and researchers specializing in mycology will find this book invaluable. Introduction II.

The skeletal muscles, like the joints, are designed to contribute to the body's needs for mobility and stability. Muscles serve a mobility function by producing or controlling the movement of a bony lever around a joint axis; they serve a stability function by resisting extraneous movement of joint surfaces and through approximation of joint surfaces.
Трансляция началась, - объявил агент Смит. Это было похоже на старое кино. Кадр казался неестественно вытянутым по вертикали и неустойчивым, как бывает при дрожащем объективе, - это было результатом удаления кадров, процесса, сокращающего видеозапись вдвое и экономящего время. Объектив, скользнув по огромной площади, показал полукруглый вход в севильский парк Аюнтамьенто. На переднем плане возникли деревья. Парк был пуст.
Даже директор не ставил под сомнение чутье Мидж Милкен - у нее была странная особенность всегда оказываться правой. - Что-то затевается, - заявила Мидж. - И я намерена узнать, что .
Оно будет громадным, - застонал Джабба. - Ясно, что это будет число-монстр. Сзади послышался возглас: - Двухминутное предупреждение.
