The fastest moving muscle in the human body is the one that closes the eyelid. This muscle is called the orbicularis muscle. The opening or closing of the eye, or the blink of the eye, was used for measuring time in ancient India. The Vedic texts designated the blink of an eye as a nimish. One nimish, according to the modern mathematical calculations, is 0.2133 seconds.
