Skeletal muscle is under voluntary, somatic nervous system control and is found in the muscles that move bones. This arrangement allows rapid transmission of electrical impulses, which stimulate virtually simultaneous contractions of the cells. As shown in Figure 12.3.6, a muscle fibre consists of a bundle of myofibrils, which are themselves bundles of protein filaments. The ability to stretch and still contract is an important attribute of smooth muscle in organs such as the stomach and uterus (see Figures 12.3.8 and 12.3.9), both of which must stretch considerably as they perform their normal functions. The heart is the muscle that performs the greatest amount of physical work in the course of a lifetime. Here, we review the current state of the art for engineering neuromuscular contacts in vitro and provide original data detailing the development of a 3D collagen-based model for the co-culture of primary muscle cells and motor neurons. Contractions of skeletal muscles are voluntary, or under conscious control of the central nervous system via the somatic nervous system. They support and protect muscle fibres, allowing them to withstand the forces of contraction by distributing the forces applied to the muscle. This is an important part of digestion. There are three types of muscle in animal bodies: smooth, skeletal, and cardiac. They vary by the presence or absence of patterns or bands, the num They are controlled by electrical impulses from specialized cardiac muscle cells in an area of the heart muscle called the sinoatrial node. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.To do all these things, cells in nervous tissue need to be able to Cardiomyopathy is a disease in which the muscles of the heart are no longer able to effectively pump blood to the body extreme forms of this disease can lead to heart failure. are licensed under a, Structural Organization of the Human Body, Elements and Atoms: The Building Blocks of Matter, Inorganic Compounds Essential to Human Functioning, Organic Compounds Essential to Human Functioning, Nervous Tissue Mediates Perception and Response, Diseases, Disorders, and Injuries of the Integumentary System, Exercise, Nutrition, Hormones, and Bone Tissue, Calcium Homeostasis: Interactions of the Skeletal System and Other Organ Systems, Embryonic Development of the Axial Skeleton, Development and Regeneration of Muscle Tissue, Interactions of Skeletal Muscles, Their Fascicle Arrangement, and Their Lever Systems, Axial Muscles of the Head, Neck, and Back, Axial Muscles of the Abdominal Wall, and Thorax, Muscles of the Pectoral Girdle and Upper Limbs, Appendicular Muscles of the Pelvic Girdle and Lower Limbs, Basic Structure and Function of the Nervous System, Circulation and the Central Nervous System, Divisions of the Autonomic Nervous System, Organs with Secondary Endocrine Functions, Development and Aging of the Endocrine System, The Cardiovascular System: Blood Vessels and Circulation, Blood Flow, Blood Pressure, and Resistance, Homeostatic Regulation of the Vascular System, Development of Blood Vessels and Fetal Circulation, Anatomy of the Lymphatic and Immune Systems, Barrier Defenses and the Innate Immune Response, The Adaptive Immune Response: T lymphocytes and Their Functional Types, The Adaptive Immune Response: B-lymphocytes and Antibodies, Diseases Associated with Depressed or Overactive Immune Responses, Energy, Maintenance, and Environmental Exchange, Organs and Structures of the Respiratory System, Embryonic Development of the Respiratory System, Digestive System Processes and Regulation, Accessory Organs in Digestion: The Liver, Pancreas, and Gallbladder, Chemical Digestion and Absorption: A Closer Look, Regulation of Fluid Volume and Composition, Fluid, Electrolyte, and Acid-Base Balance, Human Development and the Continuity of Life, Anatomy and Physiology of the Male Reproductive System, Anatomy and Physiology of the Female Reproductive System, Development of the Male and Female Reproductive Systems, Maternal Changes During Pregnancy, Labor, and Birth, Adjustments of the Infant at Birth and Postnatal Stages, (a) Skeletal muscle cells have prominent striation and nuclei on their periphery.
