During the cross bridge cycle, what is the first event that occurs after ATP binds myosin? the power stroke occurs myosin releases actin myosin binds actin to form another cross bridge myosin enters its energized state
Distinguish between skeletal, smooth, and cardiac muscle in terms of location and whether they have sarcomeres. Use the sliding filament model to draw how thin filaments, thick filaments, and Z lines move during muscle contraction. Predict how perturbations of acetylcholine release, reception, or breakdown will influence muscle contraction. Predict how perturbations of actin, troponin, tropomyosin, myosin, or calcium would influence muscle contraction. Distinguish between the sympathetic and parasympathetic nervous system. Predict how changes in stress levels or situations would affect activation of the sympathetic and parasympathetic nervous system, levels of epinephrine and norepinephrine, and blood pressure.
Compared to skeletal muscle, smooth muscle None of the choices are correct Has equal thick and thin filaments Uses calcium from the extracellular fluid only Has the same contractile and regulatory proteins. Has much more thick filaments than thin filaments
Which type of contraction is associated with increased skeletal muscle fiber damage? concentric eccentric asymmetrical isometric
What happens when the muscular action potential spreads through transverse (T) tubules of the sarcolemma? The action potential in T tubules triggers the release of acetylcholine from the axon terminals of the motor neuron. The action potential in T tubules triggers closing of sodium channels and opening of potassium channels, which enables myosin cross bridges to form. The action potential in T tubules opens voltage-sensitive calcium channels in the T tubules, allowing calcium to flow into the sarcoplasm. The action potential in T tubules causes a shape change in voltage-sensitive proteins that pull open calcium channels in the sarcoplasmic reticulum.
A muscle cannot respond to appropriate nerve stimuli. Which muscle characteristic is impaired? Contractility Extensibility Elasticity Irritability
