Really good I use it quite frequently I've had no problems with it yet. Get started for free! Muscular thermoregulation-In rest, contractions of skeletal muscles produce up to 30% of the body heart. the basic contractile unit of striated muscle; the segment of a myofibril between two adjacent z-lines. Your first task is to learn about the different types of muscle tissues found in the human body. Figure 15.3. For muscle cell contraction, the initial sources of energy (ATP) are intracellular ATP (4-6 seconds), creatine phosphate (another 10-15 seconds), aerobic metabolism (fatty acids -rest or light exertion, and glucose), and anaerobic metabolism (1 to 2 minutes). Smooth muscle is in walls of hollow organs, spindle-shaped cells, nonstriated, uninucleate, and involuntary. In rest, contractions of skeletal muscles produce up to 30% of the body heat. Define the sliding filament theory of skeletal muscle contraction. Slow red oxidative fibers (type 1) have high myoglobin content, have mitochondria and capillaries, contract slowly and are for resistance to fatigue. I am thankful to the authority of This app for making this application. - May convert fast glycolytic fibers into fast oxidative fibers, exercise that forces muscles to contract against increased resistance; also called strength training, fibers parallel to long axis of organ; contraction dilates and shortens, fibers in circumference of organ; contraction --> constricts lumen, elongates organ, numerous bulbous swellings in the nerve fibers, indentations in sarcolemma; may act like T tubules, tethered to the sarcolemma, act as anchoring points for thin filaments and therefore correspond to Z discs of skeletal muscle, allows a hollow organ to fill or expand slowly to accomodate a greater volume without promoting contractions that would expel their contents, unitary smooth muscle; arranged in opposing sheets, innervated by variscosities, contract as a unit, respond to various chemical stimuli, in the large airways to lungs and in large arteries, arrector pili, internal eye muscles; fibers are structurally independent, richly supplied with nerve endings, responds to neural stimulation with graded contractions that involve recruitment, stem cells that fuse to form each muscle fiber, David N. Shier, Jackie L. Butler, Ricki Lewis, Human Anatomy and Physiology Laboratory Manual, Elaine N. Marieb, Lori A. Smith, Susan J. Mitchell, Anatomy and Physiology: The Unity of Form and Function.
