What contains scala vestibuli and cochlea?
The scala vestibuli and scala tympani are two of the three fluid-filled chambers within the cochlea of the inner ear. The scala vestibuli is located above the cochlear duct, while the scala tympani is located below. These chambers are responsible for transmitting sound vibrations and fluid pressure changes within the cochlea.
What are the inner ear chambers?
The inner ear consists of three chambers: the cochlea, the vestibule, and the semicircular canals. The cochlea is involved in hearing, while the vestibule and semicircular canals help with balance and spatial awareness. These chambers are filled with fluid and contain specialized cells responsible for detecting sound waves and head movements.
Is the part of the ear that is set into vibration by vibrating air molecules the cochlea?
The eardrum is the first thing that vibrates in response to vibrating air or "sound". The cochlea is the last step in the process, and instead of vibrating it is filled with fluid that moves in response to vibration on a small window on the side. This moves the cochlear fluid and then is transferred to the brain through small hairs inside the organ. Three tiny bones (Malleus, Incus, and Stapes) transfer the vibration from the eardrum to the cochlea.
Which activity best describes the function of the inner ear?
The inner ear comprise of three intimately related structures - the cochlea (spiral tube), three semicircular canals and the vestibule (labyrinth). The cochlea is directly responsible for hearing and contains nerves responsible for converting energy vibrations within the inner ear fluid into nerve impulses which can be transmitted to the brain. While the vestibule (labyrinth) and semicircular canals function to maintain balance or equilibrium.
Which of the three ossicles strike the cochlea?
The auditory ossicles are located in the middle ear. Their function is to transmit and amplify the sound vibrations from the tympanic membrane (eardrum) to the oval window.tympannic side = malleus or hammermiddle = incus or anviloval window side = stapes or stirrupThe stapes/stirrup are the nearest ossicle to the cochlea of the inner ear.

The scala vestibuli is located above the cochlear duct, while the scala tympani is located below.

What portion of the ear is divided into three channels?
The portion of the ear divided into three channels is the cochlea, which is part of the inner ear. The cochlea contains three fluid-filled compartments: the scala vestibuli, scala media, and scala tympani. These channels play a crucial role in the process of hearing by converting sound vibrations into neural signals.
What are the contents of the cochlea in the ear?
The cochlea structure consists of three adjacent tubes separated from each other by sensitive membranes. These tubes are coiled in the shape of a snail shell and filled with fluid. Its' job is to take the physical vibrations caused by the sound wave and translate them into electrical information the brain can recognize as distinct sound.
What are the inner ear chambers?
The inner ear consists of three chambers: the cochlea, the vestibule, and the semicircular canals. The cochlea is involved in hearing, while the vestibule and semicircular canals help with balance and spatial awareness. These chambers are filled with fluid and contain specialized cells responsible for detecting sound waves and head movements.
What creates pressure waves in the cochlea?
Sound waves act on the eardrum, which drives a set of three tiny bones, of which the stirrup acts upon the Oval Window of the Cochlea, thus inducing pressure waves in the fluid of that organ. These waves move the signal hairs and thus their nerves which communicate with the brain.
Describe how vibrations produced in your ear by a sound wave enable you to hear the sound?
When a sound wave enters the ear, it causes the eardrum to vibrate. These vibrations are then passed through the three small bones in the middle ear to the cochlea, which is filled with fluid. The movement of the fluid stimulates hair cells in the cochlea, which convert the vibrations into electrical signals that are sent to the brain and interpreted as sound.

Structures composing the bony or osseous labyrinth?
The ossicles of the middle ear are positioned and connected by miniature ligaments, tendons, and joints. The cochlea, semicircular canals, and vestibule of the inner ear are linked. They are all fluid filled, and encased and protected inside the thickness of the skulls temporal bone. Together they occupy the series of tunnels and chambers known as the osseous labyrinth.
How does longitudinal waves in the air produce longitudinal waves in the cochlear fluid of the inner ear?
The pressure wave in the air enters the ear canal and vibrates the tympanic membrane (the ear drum) the ear drum vibrates the malleus (hammer), the incus (anvil) and the stappes (stirrup) in the middle ear. These bonds vibrate the oval window (into the cochlea) and the oval window produces a pressure wave in the fluid in the inner ear.
How do sound vibrations reach the cochlea?
Sound waves cause the thin skin of the eardrum to vibrate. This vibration, in turn, vibrates a chain of three tiny bones which are attached, at one end of the chain, to the eardrum, and at the other end of the chain, to a thin drumlike structure on on the opening to the cochlea. The vibration of this "round window" as it is called, causes the fluid inside the cochlea to flow, which in turn causes tiny hairs inside the cochlea to move. These hairs, when moved, send signals to the brain which are interpreted as sound.
How many syllables does cochlea have?
There are three syllables. Coch-le-a.
