inner ear
The part of the vertebrate ear which contains
the organs of hearing and balance. The inner
ear is surrounded by the temporal bone
of the skull and is connected to the brain
by the auditory nerve. It consists
of of two connected chambers with sensory walls. From one, the utricle,
arise the semicirculuar canals,
which are concerned with balance. From the other, the sacculus,
arises the cochlea. The whole inner ear
is filled with a fluid (endolymph) and is separated from the surrounding
skull wall by another fluid (perilymph).
