The calcium carbonate that the otolith is composed of is primarily derived from the water. As the otolith grows, new calcium carbonate crystals form. As with any crystal structure, lattice vacancies will exist during crystal formation allowing trace elements from the water to bind with the otolith.
Perilymph and endolymph have unique ionic compositions suited to their functions in regulating electrochemical impulses of hair cells necessary for hearing. The electric potential of endolymph is ~80-90 mV more positive than perilymph due to a higher concentration of potassium cations (K +) in endolymph and higher sodium (Na +) in perilymph. [4]
Otoconia are crystals of calcium carbonate and make the otolithic membrane heavier than the structures and fluids surrounding it. [1] The otoconia are composite crystallites that overlie the macular sensory epithelium of the gravity receptors of most vertebrates and are required for optimal stimulus input of linear acceleration and gravity.

Myringosclerosis refers to a calcification only within the tympanic membrane and is usually less extensive than intratympanic tympanosclerosis, which refers to any other location within the middle ear such as the ossicular chain, middle ear mucosa or, less frequently, the mastoid cavity.
An earworm happens when you have the “inability to dislodge a song and prevent it from repeating itself” in your head, explains Steven Gordon, M.D., neurotologist at UC Health and assistant ...
When the patient is passively positioned from an upright seated posture down to a supine (lying on the back) position, this momentum helps to dislodge the otoconia (crystal) embedded in the cupula. Steps 3–10 in the above-mentioned procedure are intended to cause the newly dislodged crystal to be brought back to the utricle through the ...
Adele is opening up about a recent health issue.. The singer, 36, told audience members at her Las Vegas residency on Friday, Oct. 25, that she is recovering from a painful ear infection that has ...
Bags of fentanyl were also found, police say. Circle K is best known for selling gas, beer and snacks, but one 24-hour store in West Florida was also offering bags of meth and fentanyl, according ...
