Define what the NMJ is and why it's important for muscle contraction. Explain in short the process of the NMJ signaling the muscle to contract. Note the difference between a motor unit and the NMJ.
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.
