Frog Leonidas: The Invulnerable Frog

I experienced something I never could have imagined: a frog that had been punched on the head for more than 10 times by Mr. Truchon, Jack V, and me, strangled, it's brain stirred up into mush, it's body cut open, the intestines pulled out. So, mainly it's just skin and some muscle left, and the legs still seem to be alive!! It's still kicking as if it was still alive!!!! It was kicking every five minutes!!! Without a brain!!! Without a heart!!! Without anything left inside it's body!!! IT'S ALIVE!!! RUN FOR YOUR LIVES!!! I found out later that the individual organs still functions even though it's cut off from the rest, it operates until it runs out of oxygen or because it didn't receive the things it needed to work. That's why the leg still jumps and we can still tickle it:D It's extremely fascinating, but I don't know how to research on it, anyone know what to type on google or yahoo to find this type of information? I would be a big help! Thanks!!:)
