The key structure in the vertebrate auditory and vestibular systems is the hair cell. . The traveling wave causes the basilar membrane and hence the Organ of.
This animation shows a simulation of " travelling wave motion" in the basilar our auditory system cope with an enormous range of possible sound amplitudes.
These lectures on the auditory system will switch back and forth between structure and .. The shape of the " traveling wave ", the distance it travels from the oval....

There should be a video here. The pinna and external auditory meatus collect these waves, change them slightly, and direct them to the tympanic membrane. At this point, one may ask how such a wiggle of a hair bundle triggers a difference in membrane potential. The motors which supply this mechanical amplification are the outer hair cells. A pressure difference between the oval window scala vestibuli and the round window scala tympani is important for generating the traveling wave along the basilar membrane, but at this stage of auditory processing the signal is still mechanical. This animation may help illustrate the important concept of resolved and unresolved harmonics. The tightly coiled shape gives the cochlea its name, which means snail in Greek as in conch shell.

The basilar membrane within the cochlea of the inner ear is a stiff structural element that separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani see figure. Your browser does not support the video tag. The influx of potassium causes a subsequent influx of calcium and a receptor potential that can cause an action potential in the afferent dendrites. The frequency is an approximately exponential function of the length of the cochlea within the Organ of Corti. Policies and Guidelines Contact. Metabolic presbycusis: differential changes in auditory brainstem and otoacoustic emission responses with chronic furosemide application in the gerbil.
