Recordings of hair cell electrical responses have shown that they transduce sound via sub-micrometer deflections of their hair bundles, which are arrays of interconnected stereocilia containing the mechanoelectrical transducer (MET) channels.The neurotransmitters diffuse across the narrow space between the hair cell and a cochlear nerve terminal, where they then bind to receptors and thus trigger action potentials in the nerve. In this way, an inner hair cell acts as mechanoreceptor that transduces vibrational into electrical energy.Transduction of mechanical vibrations. The hair cells located in the organ of Corti transduce mechanical sound vibrations into nerve impulses. They are stimulated when the basilar membrane, on which the organ of Corti rests, vibrates.

How do hair cells transduce an auditory stimulus?
The neurotransmitters diffuse across the narrow space between the hair cell and a cochlear nerve terminal, where they then bind to receptors and thus trigger action potentials in the nerve. In this way, an inner hair cell acts as mechanoreceptor that transduces vibrational into electrical energy.
How do inner hair cells transduce sound?
Transduction of mechanical vibrations. The hair cells located in the organ of Corti transduce mechanical sound vibrations into nerve impulses. They are stimulated when the basilar membrane, on which the organ of Corti rests, vibrates.

How the hair cells transduce sound intensity and frequency?
Intensity (volume) of sound is determined by how many hair cells at a particular location are stimulated. The hair cells are arranged on the basilar membrane in an orderly way. The basilar membrane vibrates in different regions, according to the frequency of the sound waves impinging on it.
How do hair cells respond to sound waves?
Hair cells in the Organ of Corti in the cochlea of the ear respond to sound. Hair cells in the cristae ampullares in the semicircular ducts respond to angular acceleration (rotation of the head). Hair cells in the maculae of the saccule and the utricle respond to linear acceleration (gravity).
How do outer hair cells amplify sound?
Outer hair cells contract and elongate with each cycle of sound as their intracellular voltage changes. This amplifies the vibration of the organ of Corti, permitting exquisite hearing sensitivity and frequency selectivity. OHCs have an intracellular turgor pressure to help maintain their shape.

In this way, an inner hair cell acts as mechanoreceptor that transduces vibrational into electrical energy.
How do hair cells Hyperpolarize?
Bending of the stereocilia toward the kinocilium (the largest of the stereocilia) opens the ion channels, leading to an inflow of ions, especially potassium, and depolarization of the hair cell. Bending of the cilia away from the kinocilium closes the ion channels and hyperpolarizes the hair cell.
Which part of cochlea determines the pitch of sound?
Inner ear, also called as labyrinth, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea. Cochlea determines the pitch of a sound.
How does sound travel through the cochlea?
The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve (auditory nerve) to the brain.
How does hair cell position in the cochlea affect the perception of sound?
Different sound frequencies are separated along the cochlea, with each hair cell being tuned to a narrow frequency range; amplification sharpens the frequency resolution and augments sensitivity 100-fold around the cell’s characteristic frequency.
What role do outer hair cells play in the transmission of sound quizlet?
Outer hair cells amplify the movement of the basilar membrane during low-intensity sound stimuli.

Where are hair cells that are stimulated by sound waves found quizlet?
The high frequency hair cells are located at the stapes end, closer the middle ear. o They receive the strongest stimulation.
How are sound wave caused?
When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.
How does the brain process sound?
The tiny hair cells in our inner ear send electrical signals to the auditory nerve which is connected to the auditory centre of the brain where the electrical impulses are perceived by the brain as sound. The brain translates the impulses into sounds that we know and understand.
Why are outer hair cells important for hearing?
Outer hair cells (OHCs) play an essential role in hearing by acting as a nonlinear amplifier which helps the cochlea detect sounds with high sensitivity and accuracy.
How do we localize sound?
Sound localization is based on binaural cues (interaural differences), or differences in the sounds that arrive at the two ears (i.e., differences in either the time of arrival or the intensity of the sounds at the right and left ears), or on monaural spectral cues (e.g., the frequency-dependent pattern of sound …
What are the differences between outer hair cells and inner hair cells?
Inner hair cells refer to the receptive cells in the cochlea, converting the sound waves into a nerve signal while outer hair cells refer to the receptive cells in the cochlea, which mechanically pre-amplify the low-level sound by the movement of the hair bundles.
How do two ears help localize sound?
With two ears, you are able to hear sounds clearly from both directions. Hearing sound from only one side of the body limits the amount of sound that you can hear clearly from the other side. This limits the range from which you can understand and comprehend noises.
How do your two ears work together to localize sound?
Working together, your two ears can detect a sound’s origin.
Having two ears—binaural hearing—allows us to locate the horizontal origin of a sound. Sound coming from the right or the left reaches one ear before the other. Our brain uses this timing difference to find the direction of the sound source.
In what way does auditory Localisation improve by moving the head?
While small head movements were found to reduce the rate of front/back confusion, moderate movements (i.e., around 16–32°) were found to be required to significantly reduce elevation errors and to almost eliminate confusions.
How do hair cells stimulate the auditory nerve quizlet?
fine filaments found in both types of hair cells, In hearing, these transform the mechanical energy of sound waves into electrical signals for the hair cells, which ultimately leads to an excitation of the auditory nerve.

What does the auditory hair cell do?
Cochlear hair cells are the sensory cells of the auditory system. These cells possess stereocilia connected to the tectorial membrane. During auditory stimulation, sound waves in the cochlea cause deflection of the hair cell stereocilia, which creates an electrical signal in the hair cell.
What do the inner hair cells do?
Inner hair cells (IHCs), the sensory cells of the cochlea, are responsible for signal transduction. Lying in a single row along the internal side of the tunnel of Corti, they are connected to type I spiral ganglion neurons (of which the axons represent about 95% of auditory nerve fibres).
