The half-somersault maneuver to move crystals out of the semicircular canals is a technique developed for at-home use without assistance. (lifeextension.com)
Outer ear, middle ear and inner ear with cochlea, sacculus, utricle and semicircular canals (the eardrum belongs to the middle ear). (zxc.wiki)
The neurosensory structures involved in hearing and equilibrium are located in the membranous labyrinth: the organ of Corti is located in the cochlear canal, while the maculae of the utricle and the saccule and the ampullae of the semicircular canals are located in the posterior section.

Inner ear2
An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates. (wikipedia.org)
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). (wikipedia.org)
Cochlea2
Vestibular sensitivity to ultrasonic sounds has also been hypothesized to be involved in the perception of speech presented at artificially high frequencies, above the range of the human cochlea (~18 kHz). (wikipedia.org)
response to an elicited acoustic startle reflex is larger in the presence of loud, low frequency sounds that are below the threshold for the mouse cochlea (~4 Hz), raising the possibility that the acoustic sensitivity of the vestibular system may extend the hearing range of small mammals. (wikipedia.org)
Occur1
Vestibular rehabilitation is an evidence-based approach to managing dizziness, vertigo, motion sensitivity, balance and postural control issues that occur due to vestibular dysfunction. (physio-pedia.com)
Balance1
Hair follicles in the saccule and utricle add to the balance information by providing feedback about the position of the head in reference to gravity (vertical orientation) as well as detecting linear motion of the head. (revitalhealth.ca)
Head1
Because of their orientation in the head, the utricle is sensitive to a change in horizontal movement, and the saccule gives information about vertical acceleration (such as when in an elevator). (wikipedia.org)
Semicircular4
The vestibular system/inner ear is a complex structure that includes 3 semicircular canals and the utricle and saccule, which contain small crystals called canalith. (northsideent.com)
As part of the inner ear, the vestibular system is responsible for sense of balance, which consists of three semicircular canals, the utricle, and the saccule. (bvsalud.org)
Otolith4
An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates. (wikipedia.org)
Here, we show regional expression of Emx2 in otolith organs, which establishes LPR, mediates the neuronal segregation across LPR and constitutes the bidirectional sensitivity function. (bvsalud.org)
Vestibular2
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). (wikipedia.org)
There is evidence that the vestibular system of mammals has retained some of its ancestral acoustic sensitivity and that this sensitivity is mediated by the otolithic organs (most likely the sacculus, due to its anatomical location). (wikipedia.org)
Organs1
The utricle and saccule are two small organs within this system that hold tiny crystals and hair cells which aid in sensing gravity and linear movement of the head. (deserthealthnews.com)
Small1
In mammals, otoliths are small particles, consisting of a combination of a gelatinous matrix and calcium carbonate in the viscous fluid of the saccule and utricle. (wikipedia.org)
Movement2
Because of their orientation in the head, the utricle is sensitive to a change in horizontal movement, and the saccule gives information about vertical acceleration (such as when in an elevator). (wikipedia.org)
2 Occasionally, the crystals get loose and fall into the canals causing an increase in sensitivity to movement and a spinning sensation with movement of the head or body position changes. (deserthealthnews.com)
Hair cells3
Sensory hair cells (HCs) in the utricle are mechanoreceptors required to detect linear acceleration. (bvsalud.org)
We conditionally knocked out ß-catenin, a canonical Wnt signaling core protein, and found that the cilia orientation of hair cells was disordered with reduced number of hair cells in the utricle. (bvsalud.org)
In conclusion, our results not only confirm that the regulation of canonical Wnt signaling affects the number of hair cells in the utricle but also provide evidence for its role in polarity development. (bvsalud.org)
Change1
In this study, we found that canonical Wnt pathway-related genes are expressed in the early stage of development of the utricle and change dynamically. (bvsalud.org)
Location1
The treatments involve moving your body in specific positions in order to mechanically move the crystals back to their proper location. (deserthealthnews.com)
