Endolymphatic infillings such as otoliths are structures in the saccule and utricle of the inner ear, specifically in the vestibular labyrinth of all vertebrates (fish, amphibians, reptiles, mammals and birds). In vertebrates, the saccule and utricle together make the otolith organs.

Alivio de la inflamación y el dolor causada por infecciones.

The otoliths (ear-stones) are small structures located in the inner ear used to register gravity and linear acceleration. Quail otoconia from Dickman et al (2004). Most creatures have otoconia. …

Otoconiile sunt biomateriale anorganice sub formă de calcit atașate firelor de păr ale celulelor senzoriale, unde indică direcția către centrul pământului. Aceste boabe de calcit permit percepția forțelor de tracțiune, de comprensiune și de forfecare. Otoliții au …

Jul 5, 2022 · These crystals are what give the otolith its name, as otolith is Greek for “ear stones”. The otoconia cause the membrane to be heavier than the structures and fluid around it.

Otoconia are bio-crystals which couple mechanic forces to the sensory hair cells in the utricle and saccule, a process essential for us to sense linear acceleration and gravity for the purpose of maintaining bodily balance. In fish, structurally similar bio-crystals called otoliths mediate both balance and hearing.

Displacements and linear accelerations of the head, such as those induced by tilting or translational movements (see Box A), are detected by the two otolith organs: the sacculus and the utricle. Both of these organs contain a sensory epithelium, the macula, which consists of hair cells and associated supporting cells.

Recent research has focused on the vestibular-evoked myogenic potential (VEMP) and the subjective visual-vertical (SVV) tests as measures of otolith function. VEMP and SVV supplement the vestibular test battery by providing information about otolith function to improve the differential diagnosis of patients with balance disorders.

One of the many tiny calcareous particles found in the utricle and sacculus of the inner ear. These move under gravitational and accelerative forces causing stimulation of hair cells and the production of nerve impulses that provide the brain with information about the position and movement of the head.

Gli otoliti sono dei piccolissimi agglomerati di ossalato e carbonato di calcio, inglobati in una matrice gelatinosa localizzata nell' orecchio interno.
