Finally, build the deadly organism by building 4 cells representative of each basic type of animal tissue: neural, epithelial, muscle and connective tissue. widely distributed in the body. The skeletal, smooth, and cardiac muscle tissues perform several important functions in our bodies: Movement External movement: Skeletal muscles are attached to bones and stretches over joints to make the skeleton move as they contract. Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control. When a brain signal reaches this junction, acetylcholine is released and an action potential is formed in the sarcolemma. Did you know that you have more than 600 muscles in your body? Fast intermediate oxidative glycolytic fibers (lla) are used for short bursts of activity . Neurotransmitters are substances which neurons use to communicate . While skeletal muscle is controlled voluntarily by the somatic nervous system, smooth and cardiac muscle tissues are controlled involuntarily by the autonomic nervous system. The major functions of muscle tissue are movement: body, parts, blood, and food; maintenance of posture (skeletal muscle); joint stability: shoulder/knee (skeletal); heat production-85% (skeletal). The result is a sustained muscle contraction, multiple motor unit summation; controls the force of contraction more precisely, stimuli that produce no observable contractions, the stimulus at which the first observable contraction occurs, strongest stimulus that increases contractile force, due to spinal reflexes that activate first one group of motor units and then another in response to activated stretch receptors in teh muscles; does not produce active movements but keeps the muscles firm, the muscle tension developed overcomes the load and muscle shortening occurs, muscle tension develops but the load is not moved, a unique high energy molecule stored in muscles; tapped to regenerate ATP while other metabolic pathways adjust to the sudden high demand for ATP, catalyzes the transfer of phosphate from CP to ADP, the initial phase of glucose breakdown; pathway occurs in both presence and absence of oxygen; glucose broken down to two pyruvic acid molecules, blood flow and oxygen delivery are impaired during vigorous muscle contraction; pyruvic acid is converted, the overall process where pyruvic acid generated durring glycolysis is converted to lactic acid, Respiration that requires oxygen and mitochondria; during rest and light to moderate exercise, the length of time a muscle can continue to contract using aerobic pathways, the point at which muscle metabolism converts to anaerobic glycolysis, Inability of muscle to maintain its strength of contraction or tension; may be related to insufficient oxygen, depletion of glycogen, and/or lactic acid buildup, excess postexercise oxygen consumption (EPOC)/oxygen debt, the extra amount of oxygen that the body must take in for restorative processes, contract slowly, have slow acting myosin ATPases, and are fatigue resistant, contract quickly, have fast myosin ATPases, and have moderate resistance to fatigue, contract quickly, have fast myosin ATPase, and are easily fatigued, such as ( which displaces tropomyosin, thus exposing myosin binding site in skeletal muscle contraction) myosin light chain kinase catalyzes transfer of phosphate from ATP to regulatory light chain of myosin, allowing the head to bind actin, and myosin binds actin - sliding filaments. the uterus during pregnancy), cells usually contract spontaneously, but can be stimulated or inhibited by the autonomic NS. manual quizlet pdf download human anatomy amp physiology. What are the 3 types of skeletal muscle fiber, and how do they differ with respect to myoglobin content, energy metabolism, and function? walls of lympatic vessels, arteries, veins, smooth muscle is also found in? When the arteries contract, blood flow to the skin decreases and less heat is lost from the body. Without these two protein filaments, muscular contraction would not be possible.
