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.
word for whiskers is vibrissae. Vibrissae are
receptive to vibrations in air currents. Whiskers vibrate as
the air moves. Mice get messages from these vibrations to
sense the presence, size, and shape of anything without
seeing or touching it. Mice seem to be moving their whiskers
most of the time. Mice have poor eye sight so their whiskers
help to protect them.
