  • By timbre

Question 4 of 6

Medal-premium 1

What is the helicotrema?

Question 5 of 6

Medal-premium 1

How is the mechanical energy transduced into neural energy within the organ of corti?

Select one of the following:

  • Cochleic cells are pushed up, bending the stereocilia against the tectorial membrane, causing an action potential

  • Cochleic cells are pushed up, bending the stereocilia against the basilar membrane, causing an action potential

  • Hair cells are pushed up, bending the stereocilia against the basilar membrane, causing an action potential

  • Hair cells are pushed up, bending the stereocilia against the tectorial membrane, causing an action potential

Question 6 of 6

Medal-premium 1

What is the function of the round window?

Select one of the following:

  • To relieve the pressure in the fluid filling the vestibular and tympanic canals

  • To let osmosis occur between the vestibular and tympanic canals

  • To let osmosis occur between the scala media and tympanic canal

  • To relieve the pressure in the fluid filling the scala media and tympanic canal
