As an action potential moves along the sarcolemma, the brief opening of voltage-gated Na+ channels will allow Na+ to rush into the muscle cell, causing the inside of the membrane at that location to become more ________. positive negative
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.
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.
