Sound vibrations within the cochlea cause vibration of the __________, which in turn causes the hairs of the spiral organ to move back and forth against the __________. The result is deformation of the hairs.
A) basilar membrane; tectorial membrane
B) basilar membrane; tympanic membrane
C) oval window; round window
D) tectorial membrane; basilar membrane

Question

Quizplus · Accepted Answer

Sound vibrations cause the basilar membrane to vibrate, which in turn causes the hairs of the spiral organ (organ of Corti) to move against the tectorial membrane, leading to the deformation of the hair cells. This process is crucial for converting mechanical sound vibrations into electrical signals that the brain can interpret as sound.
