Is the basilar membrane receive sound waves via air?
I think basilar membrane is the receptors for sounds stimuli.
What Forms the floor of the cochlea?
Basilar membrane
What is the length of the basilar membrane?
About 3.5 cm
A basilar membrane would be found in?
Auditory nerve
What causes the cochlea to vibrate?
The inner ear is a snail-shaped structure called the cochlea, which is filled with fluid. When the oval window vibrates, it causes the fluid in the cochlea to vibrate. This fluid surrounds a membrane running through the middle of the cochlea called the basilar membrane. The answer of your question is the Basilar Membrane.
What is the function of organ of corti?
the organ of corti is found inside the cochlea in the middle ear. in the organ of corti are hair cells which pick up vibrations. these vibrations are what is processed by the brain as sound. so basically without it no vibrations and hence the brain will not be able to interpret the vibrations into sounds
What converts sound vibrations into electrical impulses?
The cochlea converts vibrations into electrical sounds
Gel-like membrane overlying the hair cells of the organ of Corti?
tectorial membrane

How are the hair cells in the cochlea stimulated when the oval window is tapped by the stapes?
When the stapes taps on the oval window of the cochlea, it creates waves of pressure within the perilymph. The pressure waves within the perilymph are transferred to the basilar membrane of the organ of corti. The vibrations of the basilar membrane cause the attached hair cells to vibrate against the tectoral membrane. These vibrations are detected by the axons extending from the spiral ganglion in to the spiral lamina, and the impulses are sent to the brain via the cochlear nerve.
Does In your inner ear different parts of the basilar membrane vibrate at different natural frequencies?
Yes. It is correct. In your ear different parts of the basilar membrane vibrate at different natural frequencies. You have stapes bone attached to oval window. When it vibrates, the vibrations are transmitted to round window. This transmission goes through scala vestibuli and comes back through scala tympani. This can happen because there is communication between to channels at the tip. When this fluid vibrates, the vibrations are taken up by different part of basilar membrane. For this you have to have the basilar membrane anatomically tapered. The longer part vibrates with low frequency sound and tapering part vibrates with sounds of higher frequencies successively. So the 'resultant' frequency is taken up by part of the basilar membrane. The signal is transmitted by hair cells to brain. With successive 'resultant' signals brain can analyse the hundreds of different sounds. Two ears together give stereoscopic effect to the sound.

What inner ear structure picks up vibrations of fluid in the cochlea and transmits them as sensory impluse to the brain?
Scala tympani is one of the perilymph-filled cavities in the cochlear labyrinth of the human ear. It is separated from the scala media by the basilar membrane, and it extends from the round window to the helicotrema, where it continues as scala vestibuli.The purpose of the perilymph-filled scala tympani and scala vestibuli is to transduce the movement of air that causes the tympanic membrane and the ossicles to vibrate, to movement of liquid and the basilar membrane. This movement is conveyed to the organ of Cortiinside the scala media, composed of hair cells attached to the basilar membrane and their stereo cilia embedded in the tectorial membrane. The movement of the basilar membrane compared to the tectorial membrane causes the sterocilia to bend. They then depolarise and send impulses to the brain via the cochlear nerve. This produces the sensation of sound.
