Vestibulo-ocular reflex: Quiz


Question 1: The semicircular canals detect head rotation and drive the rotational VOR, whereas the ________ detect head translation and drive the translational VOR.
Inner earOtolithBasilar membraneRound window

Question 2: The ________ is essential for motor learning to correct the VOR in order to ensure accurate eye movement.
White matterCerebellumRhombencephalonHuman brain

Question 3: It starts in the vestibular system, where semicircular canals get activated by head rotation and send their impulses via the vestibular nerve (cranial nerve VIII) through Scarpa's ganglion and end in the vestibular nuclei in the ________.
Grey matterBrainstemHuman brainWhite matter

Question 4: The VOR is ultimately driven by signals from the vestibular apparatus in the ________.
Inner earMiddle earSemicircular canalCochlea

Question 5: Review on VOR adaptation via slides at ________
Carnegie Mellon UniversityStanford UniversityFlorida State UniversityJohns Hopkins University

Question 6: The vestibulo-ocular reflex (VOR) or oculovestibular reflex is a reflex eye movement that stabilizes images on the ________ during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field.
RetinaCiliary muscleScleraIris dilator muscle

Question 7: ________ consumption can disrupt the VOR, reducing dynamic visual acuity.

Question 8: One pathway projects directly to the lateral rectus of eye via the ________.
Oculomotor nerveAbducens nerveGlossopharyngeal nerveTrochlear nerve

Question 9: There they project and stimulate the lateral rectus of the left eye via the ________.
