inner ear
Cochlea's home turf
The inner ear is the deepest part of the ear, containing the cochlea for hearing and the semicircular canals for balance.
It converts sound vibrations into nerve signals and detects head position and movement.
Inner ear problems cause hearing loss, vertigo, or dizziness: an inner ear infection, inner ear damage from loud noise.
