The three types of muscle tissue are skeletal, cardiac, and smooth. Smooth muscle contracts under certain stimuli as ATP is freed . 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 A sarcomere is a regular arrangements of thick and thin filaments; it is the distance from one Z disc to another.

The skeletal, smooth, and cardiac muscle tissues perform several important functions in our bodies: External movement: Skeletal muscles are attached to bones and stretches over joints to make the skeleton move as they contract. Skeletal muscle fibers can be quite large for human cells, with diameters up to 100 m and lengths up to 30 cm (11.8 in) in the Sartorius of the upper leg.During early development, embryonic myoblasts, each with its own nucleus, fuse with up to hundreds of other . The A band does not change its length, but the I bands and H bands shorten which brings the Z bands closer together. When a brain signal reaches this junction, acetylcholine is released and an action potential is formed in the sarcolemma. exam 1 flashcards quizlet human anatomy physiology i lab online course university of north dakota p d f . From what embryonic tissue(s) does muscle tissue develop? Skeletal muscle is attached to bones, has cylindrical cells, is striated, multinucleate, and voluntary control. Remember that you can access the theory pages in your LabPad at any moment while playing the simulation. 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). Market interest rates dropped and the company called the bonds (i.e., paid them off in advance) at a 10% premium on the face value. It depends on where they are sectioned. Let knowledge be the cure.
