Final answer:
The neurotransmission of hearing impulse begins in the hair cells of the inner ear, specifically in the organ of Corti.
Step-by-step explanation:
The neurotransmission of hearing impulse begins in the organ of Corti, specifically in the hair cells of the inner ear. These hair cells, which are the primary auditory receptors, are located in the spiral organ above the basilar membrane. When sound waves enter the cochlea, the basilar membrane flexes and bends the stereocilia of the hair cells, resulting in the generation of action potentials. These action potentials then travel along the auditory nerve to the brain, where the sound is processed and interpreted.
