inner ear


The inner ear refers to the bony labyrinth, the membranous labyrinth and their contents. It may also be referred to as the vestibulocochlear organ, supplied by the vestibulocochlear nerve (CN VIII). It is divided into three main parts:
- the cochlea housing the cochlear duct for hearing
- the vestibule housing the utricle and saccule for static balance
- the semicircular canals housing the semicircular ducts for kinetic balance
As the membranous labyrinth is slightly smaller than the osseous labyrinth, the two are separated by perilymph, which does not communicate with the endolymph contained in the membranous labyrinth.
