What is the basilar membrane quizlet?
What is the basilar membrane quizlet?
membrane that serves as the floor of the organ of Corti. It has a stiffness gradient. Basal end is narrow and stiff, the apical end is wider and flaccid.
What is basilar membrane anatomy?
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 is the basilar membrane What is its function quizlet?
The basilar membrane supports the organ of Corti containing hair cells, each with stereocilia. It is a structure in the cochlea of the inner ear that produces nerve impulses in response to sound vibrations.
What is the basilar membrane What is its function?
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 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.
What does movement of the hair cells along the basilar membrane?
As the basilar and tectorial membranes move up and down with the traveling wave, the hinge mechanism causes the tectorial membrane to move laterally over the hair cells. This lateral shearing motion bends the cilia atop the hair cells, pulls on the fine tip links, and opens the trap-door channels (See Figure 12.1).
How many hair cells are in a basilar membrane?
Hair cells are spread across a flat surface called the basilar membrane, which is rolled like a carpet and tucked into a snail shell-shaped structure in the inner ear called the cochlea. Each of our roughly 16,000 hair cells is dedicated to a narrow frequency range.
What is the function of the cochlea quizlet?
Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea.
Is basilar membrane part of hearing?
…important for hearing is the basilar membrane, stretching the length of the snail-shaped cochlea and dividing it into two interior canals. Békésy found that sound travels along the basilar membrane in a series of waves, and he demonstrated that these waves peak at different places on the membrane: low frequencies…
What is basilar membrane in psychology?
Are cilia on basilar membrane?
Sound waves cause the basilar membrane to move relative to the tectorial membrane. The cilia of the hair cells bend when contact is made to the tectorial membrane and the hair cell discharges.
What kind of receptor are the hair cells on the basilar membrane?
auditory receptor cells
The auditory receptor cells, called hair cells, lie embedded within the basilar membrane. This membrane divides the spiraled cochlea into upper and lower chambers. Movement of the fluid within the cochlea causes stimulation of the hair cells.
What kind of receptor are the hair cells on the basilar membrane quizlet?
Hearing receptors are connected to the basilar membrane by supporting cells. 4. Hearing receptors are called hair cells.
What is the function of the cochlea or cochlear duct?
The receptors for the organ of hearing are contained in the cochlear duct, while those for the organ of balance are contained in the utricle, saccule, and the three semicircular ducts. The cochlear duct (organ of hearing) communicates with the saccule (organ of balance) via the ductus reuniens.
How does the basilar membrane 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. This stimulates the sensory cells of the organ of Corti, atop the basilar membrane, to send nerve impulses to the brain.
What happens when basilar membrane vibrates?
The wave motion is transmitted to the endolymph inside the cochlear duct. As a result the basilar membrane vibrates, which causes the organ of Corti to move against the tectoral membrane, stimulating generation of nerve impulses to the brain.
What is the surface of the basilar membrane lined with?
The surface of the basilar membrane is lined with: hair cells.
What kind of receptors are hair cells rod cells and cone cells and to which of your senses do these cells contribute?
The Senses: receptors / rod and cone cells. Vision: rod and cone cells of the eye’s retina are specialized to respond to the electromagnetic radiation of light. Hearing: the ear’s receptor neurons are topped by hair bundles that move in response to the vibrations of sound.
What is the function of the basilar membrane?
What is the basilar membrane What is its function? 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 does the basilar membrane do?
The basilar membrane is the main mechanical element of the inner ear. It possesses graded mass and stiffness properties over its length, and its vibration patterns have the effect of separating incoming sound into its component frequencies that activate different cochlear regions.
What does basilar membrane mean?
The basilar membrane is a structural element that divides the cochlea – which is essentially a long tube – down the middle into two liquid-filled tubes: the scala media and the scala tympani. If A Vaccinated Person Donates Their Blood, Does Its Receiver Gets Their Immunity? The basilar membrane in an uncoiled cochlea.
What is basilar membrane lined with?
…the basilar membrane is the organ of Corti, an array of hair cells with stereocilia that contact a gelatinous membrane called the tectorial membrane. Sound entering the inner ear stimulates different regions of the basilar membrane, depending on sound frequency. READ: What cells in the leaf perform the most photosynthesis?
