It is thought that pain results from a change in the pH of the fluid thar surrounds nerve cells. The fluid within your cells is slightly acidic, so a cut or burn releases this fluid and cause pain signals from your nerve endingd. What would you expect to find if you tested the pH creams and lotions used to treat cuts or burns?

T requires that all motions be continuous, then it cannot be a natural motion for a body to be at two distinct places at two different times but at no intermediate place during that interval. If this is correct Does it change any of the properties of L`?

Due to the fact that the urinary bladder is innervated by the autonomic nervous system, and that sympathetics are responsible for increasing muscle tone of the sphincter, while decreasing the muscle tone of the bladder wall (while the opposite is true for parasympathetic stimulation) it seems counter-intuitive for a "flight-or-fight" situation to cause this. Am I missing something? Ok, obviously I am, but what?
