Verified
Audition depends on the movement of ________ on the surface of the basilar membrane triggering impulses in adjacent nerve cells.
A) hair cells
B) the eardrum
C) vestibular sacs
D) olfactory receptors
Audition
The sense of hearing or the act of listening.
Basilar Membrane
A key structure in the cochlea of the inner ear, responsible for converting sound vibrations into neural signals.
Hair Cells
Sensory cells located in the inner ear that are responsible for converting sound vibrations into electrical signals.
- Comprehend the process of sound wave transmission from the external environment to the auditory cortex.
- Grasp the concept of auditory processing and the relevance of the cochlea and hair cells in hearing.

Final Answer :
A
Explanation :
The movement of hair cells on the surface of the basilar membrane is what triggers impulses in adjacent nerve cells, which are then processed by the brain as sound. The eardrum is involved in the process of hearing, but specifically in capturing sound waves and transmitting them to the inner ear; it does not directly trigger impulses in nerve cells. Vestibular sacs are involved in the sense of balance, not hearing. Olfactory receptors are involved in the sense of smell, not hearing.
