the basilar membrane is found in the cochlea; it forms the base of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti.

Subsequently, What is basilar membrane in psychology?
a fibrous membrane within the cochlea that supports the organ of Corti. In response to sound, the basilar membrane vibrates; this leads to stimulation of the hair cells—the auditory receptors within the organ of Corti. The location of the maximum movement depends on the frequency of the sound. …
Also, How does the basilar membrane respond to a sound wave?
When the sound waves in the cochlear fluid contact the basilar membrane, it flexes back and forth in a wave-like fashion. Above the basilar membrane is the tectorial membrane.
Why is it important for the basilar membrane to move quizlet?
Why is it important for the basilar membrane to move? Movement of the basilar membrane causes hair cells to bend, releasing neurotransmitters.

What is the function of the basilar membrane hair cells and Tectorial membrane?
The movement of the basilar membrane causes hair cell stereocilia movement. The hair cells are attached to the basilar membrane, and with the moving of the basilar membrane, the tectorial membrane and the hair cells are also moving, with the stereocilia bending with the relative motion of the tectorial membrane.
What is the function of basilar membrane?
the basilar membrane is found in the cochlea; it forms the base of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti.
What is the major role of the basilar membrane quizlet?
What is the major role of the basilar membrane? The basilar membrane supports the spiral organ, and vibrations are transmitted through the basilar membrane to the hair cells of the spiral organ.
What is the role of the basilar membrane in hearing?
the basilar membrane is found in the cochlea; it forms the base of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti.
Why is it important for the basilar membrane to move?
Why is it important for the basilar membrane to move? Movement of the basilar membrane causes hair cells to bend, releasing neurotransmitters. … The organ of Corti is the structure along the basilar membrane that contains the hair cells that transduce sound into a neural signal.
What is the function of the basilar membrane?
the basilar membrane is found in the cochlea; it forms the base of the organ of Corti, which contains sensory receptors for hearing. Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti.
What is the basilar membrane of the ear?
The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani.
What sensory organ is supported by the basilar membrane?
organ of Corti
How does the frequency of sound waves determine the movement of the basilar membrane?
The higher the frequency of the sound imposed, the shorter the distance the waves travel. Thus, a tone of a given frequency causes stimulation to reach a peak at a certain place on the basilar membrane. … Loudness also is determined at this level by the amplitude, or height, of the vibration of the basilar membrane.
How are different frequencies represented on the basilar membrane?
When sound pressure is transmitted to the fluids of the inner ear by the stapes, the pressure wave deforms the basilar membrane in an area that is specific to the frequency of the vibration. In this way, higher frequencies cause movement in the base of the cochlea, and deeper frequencies work at the apex.
Where is the basilar membrane most sensitive to the vibrations of very high frequency sound waves?
The basilar membrane vibrates in different regions, according to the frequency of the sound waves impinging on it. Likewise, the hair cells that lay above it are most sensitive to a specific frequency of sound waves.
What is the function of the Tectorial membrane?
The tectorial membrane (TM) is an extracellular connective tissue that covers the mechanically-sensitive hair bundles of the sensory receptor cells in the inner ear. It occupies a strategic position, playing a key role in transforming sound to mechanical stimulation.
What do different parts of the basilar membrane respond to?
Basilar membrane.

Which of the following explains how the frequency of sound waves determines the movement of the basilar membrane?
Which of the following explains how the frequency of sound waves determines the movement of the basilar membrane? (1.0 points) A)Higher-frequency waves move the region of the basilar membrane that is close to the base of the cochlea, whereas lower-frequency waves move the region that is near the tip of the cochlea.
What causes the basilar membrane to move?
When the waves reach the tympanic membrane, they cause the membrane and the attached chain of auditory ossicles to vibrate. The motion of the stapes against the oval window sets up waves in the fluids of the cochlea, causing the basilar membrane to vibrate.
