• head
  • They tell the brain when our head moves in a rotating or circular way, such as when we nod our head up and down or look from right to left. (medicinenet.com)
  • When the head moves, fluid inside the semicircular canal moves. (medicinenet.com)
  • A head tilt causes stimulation of both anterior semi-circular canals and the posterior semi-circular canals resulting in excitation of ipsilateral intorters (superior oblique and superior rectus) and contralateral extorters (inferior oblique and inferior rectus) while their antagonists are simultaneously inhibited. (wikipedia.org)
  • The initial head tilt to right will cause stimulation of the right utricle resulting in excitory signals to pass to the SR and SO (right eye), and IO and IR (left eye). (wikipedia.org)
  • In case of any lesion from the utricle to the brainstem, diminished input from the affected vestibular pathway, for example the left vestibular is the same as stimulation of right vestibular pathway, resulting in the erroneous interpretation by the brain that the head is tilted to the right and consequently that the SVV is tilted to the left. (wikipedia.org)
  • The saccule and utricle detect different motions, which information the brain receives and integrates to determine where the head is and how and where it is moving. (wikipedia.org)
