Questions and Answers

What guides the pre-natal establishment of tonotopic organization in the cochlea?

Activation of the auditory nerve cells
Synaptic reorganization (correct)
Changes in the basilar membrane width
Structural changes in the hair cells

Why does the apical end of the basilar membrane respond best to low-frequency sounds?

Due to its narrow and stiff structure
Because it is the location of the auditory nerve cells
Because of its proximity to the oval window
As a result of maximal vibration when exposed to low frequencies (correct)

What creates tonotopy in the cochlea?

The tectorial membrane above the basilar membrane
The presence of hair cells
The gradient of frequency response along the basilar membrane (correct)
The activation of synaptic connections
