Single muscle twitch:
It is a muscle contraction initiated by a single brief-stimulation. It occurs in 3 stages: a latent period of no contraction, a contraction period and a relaxation period.
1. The involuntary contraction of muscle fibers is known as muscle twitch.
2. Muscle twitch is also known as fasciculation.
3. It is caused due accumulation of lactic acid in muscles.
