the cells of the hairs don't detect the sound waves at all. The full hair is vibrated by the sound waves and this vibration is picked up by nerves and the info is sent to the brain.

What does the cochlea turn the vibrations into?
ELECTRICAL SIGNALS gees.
Sensory receptors of the ear?
The cochlea; sound wave are transferred through the ear canal and vibrated the ear drum which is connected to the cochlea and amplified the sound wave. When the sound wave reached the cochlea, sound wave is converted into nerve impulse and transferred through the nerve to the brain. Receptor is a converter of stimulus to electrical nerve impulse ; cochlea converted sound wave into nerve impulse and so cochlea is the sensory receptor of the ear.
What is a cochlea and what is its role?
The cochlea is the inner ear. It transforms sound into a message the nerves can carry to the brain.
Where in your body can you find the cochlea?
YOUR EARS : Sound comes into the inner ear as vibrations and enters the cochlea
What is the role of cochlea in ear?
The cochlea is the place where sound is actually sensed by nerves to create a signal that can travel to the brain. The rest of the ear serves only to collect sound and transmit it to the cochlea.
Is the cochlea an organ?
Yes, the cochlea is the organ in the ear that helps transmit sound signals to the brain.
What is cochela?
The cochlea is an internal part of your ear, and is the part where sound is converted into the movement of tiny hair cells and thus generate electrical signals that we interpret as sound. The cochlea is curled up like a shell, hence the name.

How is hearing affected if a person 's cochlea is damaged?
The cochlea is the part of the inner ear that takes vibrations, transferred from sound waves hitting the eardrum (tympanic membrane) and converts them into signals for the auditory nerve. Different parts of the cochlea "encode" different frequencies (pitches) of sound. Therefore, if only part of the cochlea is damaged, a person may lose the ability to hear certain frequencies of sound. If it is damaged enough, the person may lose the ability to hear completely in one 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.
What part of the ear changes vibrations into nerve signals?
The cochlea.
What part of the ear converts vibrations to action potentials?
The inner ear contains the receptors for sound which convert fluid motion into action potentials that are sent to the brain to enable sound perception. The airborne sound waves must be transferred into the inner ear for hearing to occur.
Does your ear or the brain do the hearing?
both. Your eardrum receives the vibrations of the sound waves, your cochlea converts that vibration into electrical signals which are then interpreted or "heard" by the auditory cortex of your brain. the brain after it picks up the sound from the ear..
What happens inside the cochlea?
A watery liquid called the perilymph moves inside the cochlea and responds to vibrations coming from the middle ear. This fluid moves over the hair cells and converts the motion into electrical signals.
How do your ears pick up sound?
Your ears pick up sound which travels in invisible waves through the air. Sound occurs when a moving or vibrating object causes the air around it to move. Sound waves travel down the ear canal and hit the eardrum in the middle ear. This causes the eardrum to vibrate. Three tiny bones in your middle ear link the vibrating eardrum to the cochlea in the inner ear. The cochlea is filled with liquid that carries the vibrations to thousands of tiny hair cells sitting on a membrane that stretches the length of the cochlea. The hair cells on the membrane fire off tiny electrical signals. These electrical signals travel up the cochlea nerves of the auditory pathway to the brain. All this happens in a fraction of a second.
