The three semicircular canals of the inner ear of " Carcharodontosaurus saharicus ", when viewed from the side, had a subtriangular outline.
42.
Purely horizontal nystagmus and symptoms of vertigo lasting more than one minute can also indicate BPPV occurring in the horizontal semicircular canal.
43.
The three semicircular canals are mutually orthogonal ( similar to three-axis accelerometer ) and are filled with a fluid called the endolymph.
44.
These inertial properties are dependent on the vestibular system, especially the semicircular canals of the inner ear, which signal rotations of the head.
45.
The vestibule is the region of the inner ear where the semicircular canals converge, close to the cochlea ( the hearing organ ).
46.
As the endolymph stabilizes, the semicircular canals stop registering the gradual turn and the aircraft slowly loses altitude until impacting with the ground.
47.
Six rotational axes about which the extraocular muscles turn the eye and the three rotational axes about which the vestibular semicircular canals measure head-movement.
48.
Research has shown that people can perceive objects without seeing them because of a change in pressure in the semicircular canals of the inner ear.
49.
Stimulation of the semicircular canals occurs when movement of the endolymph inside the canals causes movement of the crista ampullaris and the hair cells within them.
50.
It involves a reorientation of the head to align the posterior semicircular canal ( at its entrance to the ampulla ) with the direction of gravity.
