Question

Quizplus · Accepted Answer

Galvani's experiment involving a frog leg proved that muscles can be activated by electrical nerve signals. He discovered that when the frog's leg was touched with a metal scalpel while a static electricity generator was running, the leg would twitch due to the electrical current. This was one of the first experiments that showed a connection between electricity and biology, and helped pave the way for later discoveries about the nervous system.
