Question

Sensory Transduction-Hearing Re-order the following list of steps (which are in alphabetical order) into the correct order for the transduction of sound waves into action potentials in the ear. . Action potentials travel along the auditory nerve to the thalamus . Ca2 enters the cell and binds to neurotransmitter-containing vesicles · Cells of the auditory nerve increase their rate of action potentials (# AP/unit time) in response to the increased neurotransmitter release hair cell is pulled down Ossicles in the middle ear transfer the vibrations of the tympanic membrane to the oval .Cilia at the top of the hair cells brush against the (static) tectorial membrane when the K" influx depolarizes the hair cell, causing a graded potential window Oval window bulges into the scala vestibuli, creating a wave in the perilymph The bases of the hair cells are pulled down as the basilar membrane is pushed down The resulting pressure wave travels through the endolymph in the cochlear duct, Some of the action potentials continue to the auditory cortex in the temporal lobe Sound waves travel through the external auditory meatus ure wave in the perilymph travels forward down the scala vestibuli and, at some point, travels sideways, pressing the vestibular membrane into the cochlea r duct pushing the basilar membrane down into the scala tympani Tip links connecting K" channels on adjacent cilia are pulled taut and the K" channels are opened Tympanic membrane vibrates Vesicles move to the synaptic membrane and release the neurotransmitter to the synapse . . . Voltage-gated Ca2 channels open in response to the depolarization
