The ability of muscle tissue to contract in response to electrical stimulation or galvanic current.
From galvano- (electricity) plus contractility (ability to contract). This scientific term from the 1800s described Galvani's original observation that electricity makes muscles twitch.
Galvani's frog legs demonstrated galvanocontractility—proving that muscles respond to electricity the same way they respond to the brain's signals, which was revolutionary proof that electricity controls movement!
