Explain, in detail, the contraction of a skeletal muscle. Start with an action potential in the axon and end with the termination of contraction. Make sure that you include all stages of ion movement and all important muscle proteins.

The S1 sound is caused by the closure of the semilunar valves.

Which form of muscle is not subject to the length-tension relationship during contraction?

Ventricular diastole occurs during what wave

Non-pacemaker contractile cells of the heart have a longer refractory period than skeletal muscle.

Enlargement of the cardiac contractile cells results in better function of the heart.

What is the most costly and leading cause of death in the United States?

The filtration described above is a result of Net Filtration Pressure. To calculate Net Filtration Pressure, you take [nfp1] minus ( [nfp2] plus [nfp3]).

The S4 heart sound is detectable in children.

Full contraction of the left side of the heart is faster than the right side of the heart.
