Question

In 1780, Galvani, studying animal electricity, connected a long wire to a dissected frog via a nerve. He put another wire from the frog's feet down a well, to ground it. As a thunderstorm approached, Galvani observed that the legs twitched every time the lightning flashed. Explain.

Answer 1

Galvani's experiment :

Connecting a long wire to a dissected frog via a nerve.Putting another wire from the feet down a well, to ground it. As thunderstorm approached , there was observation that legs were twitched every time the lightening flashed.

It proved not only that recently dead muscle tissue can respond to external electrical stumili , but the muscle and nerve cells possess an intrinsic electrical force that is responsible for muscle contractions and nerve conduction in living organism.

Hence it was important discovery of animal electricity by Galvani.
