| 31. | The vestibular system is the region of the inner ear where the semicircular canals converge, close to the cochlea.
|
| 32. | Unlike jawed vertebrates, which have three semicircular canals in each inner ear, lampreys have only two and hagfishes just one.
|
| 33. | Lampreys have only two semicircular canals, with the horizontal canal being absent, while hagfish have only a single, vertical, canal.
|
| 34. | The utricle and saccule are sensors for detecting angular or linear acceleration, and the three semicircular canals detect head rotation.
|
| 35. | The semicircular system of MCCM-HUE-8741 shows also a basal morphology, because the semicircular canals do not attach to each other.
|
| 36. | In rare cases, the crystals themselves can adhere to a semicircular canal cupula, rendering it heavier than the surrounding endolymph.
|
| 37. | The semicircular canals, found within the vestibular apparatus, let us know when we are in a rotary ( circular ) motion.
|
| 38. | BPPV is the most common cause of vertigo, a problem attributed to a detached otoconia in one of the semicircular canals.
|
| 39. | Because of this, even though the Earth's gravity is a constant force of acceleration, the semicircular canals do not respond to it.
|
| 40. | For some patients, this maneuver may not be indicated, and a modification may be needed that also targets the posterior semicircular canal.
