Galvanism

Galvanism refers to the generation of electrical currents in the body caused by contact with external electrical sources. The term originates from Luigi Galvani, who discovered that frog muscles twitch when touched by electricity. In medical and scientific contexts, galvanism involves applying controlled electrical impulses to tissues to study or influence nerve and muscle behavior. Historically, it played a role in early experiments exploring the relationship between electricity and biological functions. Today, galvanism is used in certain medical treatments (e.g., electrical stimulation therapy) and in understanding bioelectric phenomena, emphasizing the body's natural electrical activity.
