Which sequence of events is required for the brain to interpret sound?
I.Vibration of the basilar membrane relative to the tectorial membrane causes cilia on hair cells to bend and triggers depolarization.
II)Hair cells stimulate the production of action potentials in sensory neurons that project to the brain.
III)Ganglion cell axons transmit action potentials to the occipital lobe.
A)II then I
B)III then I then II
C)III then I
D)I then II
E)I then II then III

Quizplus · Accepted Answer

The sequence of events required for the brain to interpret sound is I then II. The vibration of the basilar membrane relative to the tectorial membrane causes cilia on hair cells to bend and triggers depolarization, which in turn stimulates the production of action potentials in sensory neurons that project to the brain. Therefore, the correct sequence is I then II. Option D is the only one with this sequence.
