Ear
The
ear
is the
organ
of the
sense
of
hearing
in the
auditory system
. In humans, the ear consists of three structures —the
inner ear
,
middle ear
and
outer ear
. The
inner ear
, contains the apparatus necessary to
change the vibrations
transmitted from the outside world via the middle ear into signals passed along the
vestibulocochlear nerve
to the
brain
. The
middle ear
, includes the
tympanic cavity
and the
ossicles
.The outer ear consists of the
auricle
or pinna, and the
ear canal
. The ear not only detects
sound
but also aids in
balance
and
body position
. The
semicircular canals
, the
utricle
and
saccule
of the inner ear also function as organs of the
vestibular system
responsible for balance.
