A mouse has movable whiskers on each side of its nose.
Whiskers are more than twice as thick as ordinary hairs.
Whisker roots are deeper than hair roots. Richly supplied with nerve endings, whiskers give mice information about air movements, air pressure, food and anything they touch. Whiskers are extremely sensitive because they are closely connected to the nervous system. The scientific word for whiskers is vibrissae. Vibrissae are receptive to vibrations in air currents.
