The labyrinth, comprising the vestibule, cochlea, and semicircular canals.
This comprises three fluid-filled chambers, or labyrinths, situated in the bony temporal area that are concerned with identifying a person’s position in space. Each chamber lies in a different plane, and movement of fluid within it is picked up by sensory cells that transmit the information to the brain. Disease or damage to the inner ear upsets the sense of balance and causes vertigo. Motion sickness is caused by the inner ear being unable to accommodate the changes in position resulting from motion.
The inner part of the ear, responsible for converting sound vibrations and maintaining balance by translating sensory input into nerve signals, is referred to as the cochlea.
The inner ear, located closest to the brain, is the deepest part of the ear and houses the organs responsible for both hearing and balance. Within the inner ear, air vibrations and various sensory stimuli, such as head movements, are registered. Special cells within this region convert this gathered information into electrical impulses, which then travel along nerves to the brain for processing. Apart from the inner ear, the ear also consists of the outer and middle ear.
