Vestibule of the Ear

The Vestibule is the central part of the inner ear, situated medial to the eardrum, behind the cochlea, and in front of the semicircular canals. It is involved in the body's sense of balance and spatial orientation.

Anatomy[edit | edit source]

The vestibule is the part of the bony labyrinth that is intermediate between the semicircular canals and the cochlea. It contains two membranous sacs: the utricle and the saccule, which respond to gravity and changes in linear acceleration.

Function[edit | edit source]

The vestibule plays a key role in the body's sense of balance. The utricle and saccule within the vestibule contain specialized cells that detect changes in motion and gravity. These signals are then sent to the brain, which interprets them and helps maintain balance and spatial orientation.

Clinical significance[edit | edit source]

Diseases of the vestibule can lead to symptoms such as vertigo, dizziness, and loss of balance. These include conditions such as Meniere's disease, vestibular neuritis, and benign paroxysmal positional vertigo.
