entry. Brilliant!!!

Well, yes, that is an intracellular messenger who's production is
stimulated by adrenaline and noradrenaline that results in contraction

Adenosine : a purine nucleoside composed of adenine linked by its N9 nitrogen to the C1 carbon of ribose. It is a component of ribonucleic acid and its nucleotides (AMP., ADP, ATP, cAMP) play important roles in biochemical processes such as synthesis of nucleic acids and proteins, photosynthesis, muscle contraction and intracellular signal transduction ------------- I'm always almost unlucky _ _ _ _ _ _ _ _ Id5ZcnjXSZaSMFMC Id5LM2q2jfqz3YxT |

indeed, it intracellularly signals for more calcium to move into the
cell, and that causes contraction (or more accurately allows
contraction to occur by binding to troponin on topomyosin and freeing
up the myosin binding sites on the actin molecule) ------------- We Lost the Skyline............

The heart beats independently of the brain's function. Therefor when you rip a heart out of a living frog it will keep beating for a couple of seconds. Of course it will stop due to lack of energie. The bigger the heart the sooner it will stop beating.
BTW. It is considered cruelty to rip hearts out of living organisms, so don't go out to test this hypothesis.

Actually, you are not entirely correct about what makes the heart beat. Although it is true that certain chemicals make cause contractions and expansions, what makes the heart beat is an "electrical" impulse that "sets off" the chemicals that permit contraction and expansion of the muscles. This is why getting certain types of electric shocks can stop your heart, and why a defibrillator works (by literally "jump-starting" the "battery"). As an aside, it is also why certain types of martial arts blows can kill; those blows are targeted at the heart, and the result of the blow is to stop the electrical impulse that keeps the heart going.

Um, actually defibrillators STOP your heart, in order to allow the natural pace maker to take over again. It's really electrochemical, not completely electrical, the potential differences being created by varying chemical concentrations, 'tis a complex process ------------- We Lost the Skyline............
