There are at least two things to consider. First, ability to limit airflow is a defense mechanism for animal. Imagine getting into area of some sort of toxic evaporation, e.g. CO2 cloud near vulcano, then it makes sense to decrease delivery of toxin via lungs to minimum. As I understand, that is what an allergic asthma attack. (Sorry for not providing good ...

Because all available ATP will likely be quickly spent by various cellular machinery. If there was 20-30mM of ATP, what would stop muscle from contraction and how could you keep ATP level constant at rest, be ready for rapid movement? By blocking all myosin? This creates enormous regulatory problems for the cell. Phosphocreatine buffers energy for a period ...

I am going to address only the stretching portion of the question since some misinformation is out there. When you say stretching, I hope you mean dynamic as opposed to static stretching especially if you are about to compete in a sport.

Short answer Proprioceptic receptors provide a feedback mechanism from the body to the brain, telling the brain what our limbs are doing and where they are with respect to the body without visual feedback being needed. Background Muscles, skin and joints contain proprioceptic receptors. They sense position and movement of our limbs and trunk, they register ...

If we're looking at diagrams for the t-tubule with respect to the sarcolemma, we see the two are actually fused: The function therein is to allow depolarization to penetrate the interior of the cell quickly. The surface isn't transected anywhere, it simply folds inward. You can visualize this by sort of pushing a hole through some putty with a finger, ...
