PATHOLOGY

Detailed explanation-1: -Muscles are stimulated by electricity. The effect depends on the intensity of the current and the type of muscle it travels through.

Detailed explanation-2: -If electric current of sufficient magnitude passes through the living tissues, its effect will be override the natural impulses of the neurons, overloading the nervous system and blocking the passage of voluntary impulses that activate in the muscles. The muscles will then involuntarily contract (tetany).

Detailed explanation-3: -During muscle contraction, chemical energy is converted to mechanical energy when ATP is hydrolysed during cross-bridge cycling. This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.
