- Q7All of the following is true in regards to localization of sounds except:Sounds from the back of the head are baffled compared with those from the front or sideThe information is processed in the brainstemThe auditory pathways are bilateral to allow for localization of soundsThe difference of decibels between the two ears allows for localization30s
- Q8The ridge of hair cells at the base of each semicircular duct are called?AmpullaeNothing, there are no hairs at the base of the semicircular ductCilia of semicircular ductsCrista ampullaris30s

- Q10All of the following are reasons for the connections between the vestibular and visuomotor network except:To help the eyes move with the movements of the headAll of the aboveTo compensate for the movements of the headTo keep the eye fixated upon an object in conjunction with movements of the head30s
- Q11Receptors in the semicircular canals detect movement of the head by sensing the motion of _________?EndolymphWaterBloodHemolymph30s
- Q12The maximal flow of fluid will occur in a semicircular canal whenAt 30°When the head turns perpendicular to the canal’s axis of rotationDuring constant rotationWhen the head turns on the canal’s axis of rotation30s
- Q13Which of the following structures respond to head position relative to gravity?AmpullaeAnterior semicircular canalUtricleCupula30s
- Q14Information derived from the semicircular canals helps to stabilize vision or keeps the eyes on target, while the otolithic organs provide information that affects the spinal cord, adjusting activity in the lower motor neurons to postural muscles.TRUEFALSE30s
