Within the labyrinth of the inner ear lie collections of calcium crystals known as otoconia or otoliths. In people with BPPV, the otoconia are dislodged from their usual position within the utricle , and over time, migrate into one of the three semicircular canals (the posterior canal is most commonly affected due to its anatomical position).
An otolith ((Ancient Greek: ὠτο-, ōto-ear + λῐ́θος, líthos, a stone) is a small crystal inside a structure in the inner ear; this structure, consisting of three hollow, connected tubes (the vestibular system) allows humans and many animals to sense orientation (up/down) in space, movement in space (including direction), and ...
The otolithic membrane is a fibrous structure located in the vestibular system of the inner ear. It plays a critical role in the brain's interpretation of equilibrium. The membrane serves to determine if the body or the head is tilted, in addition to the linear acceleration of the body. The linear acceleration could be in the horizontal ...

The utricle and saccule are the two otolith organs in the vertebrate inner ear.The word utricle comes from Latin uter ' leather bag '.The utricle and saccule are part of the balancing system (membranous labyrinth) in the vestibule of the bony labyrinth (small oval chamber). [1]
The cupula is the onion-shaped structure surrounded by endolymph in the ampulla. The ampullary cupula, or cupula, is a structure in the vestibular system, providing the sense of spatial orientation.
For removing ear wax at home, Dr. Tonia recommends putting 5–10 drops of hydrogen peroxide into the ear canal, laying like Ayisha in the TikTok for 5 minutes.
It also contains an inner membranous sleeve that lines the semicircular canals. The canals also contain the crista ampullaris. The receptor cells located in the semicircular ducts are innervated by the eighth cranial nerve, the vestibulocochlear nerve (specifically the vestibular portion).
