What Does The Basilar Membrane Do?
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.a fibrous membrane within the cochlea that supports the organ of Corti
What is the main function of the basilar membrane?
What is the basilar membrane and why is it important?
How does the basilar membrane work?
What is the function of the basilar membrane quizlet?
The vibration of the basilar membrane causes a bending of the stereocilia of the hair cells against the tectorial membrane, which is where the nerve impulse is created. The Vestibulocochlear nerve (CN VIII) transmits the nerve impulse to the brain.
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. …
What does the basilar membrane detect?
The basilar membrane acts as a spectral analyzer that translates vibration frequencies within the cochlear fluid pressure waves into positions of maximal displacement along its length.
How does the basilar membrane respond to a sound wave?
When sound waves produce fluid waves inside the cochlea, the basilar membrane flexes, bending the stereocilia that attach to the tectorial membrane.
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 the basilar membrane lined with?
The surface of the basilar membrane is lined with: hair cells.
What is the function of the basilar membrane hair cells and tectorial membrane?
Within the cochlea lies the Organ of Corti. This structure is composed of the basilar membrane, the hair cell receptors, and the tectorial membrane. The tectorial membrane (from tectum meaning roof) lies over the hair cells; it serves as a shelf against which the cilia of hair cells brush upon movement.
What is the relationship between the basilar membrane and Tonotopic organization?
What is the purpose of the tympanic membrane quizlet?
The tympanic membrane’s function is to assist in human hearing. When sound waves enter the ear, they strike the tympanic membrane. The membrane vibrates with the force of the sound wave strike and transmits the vibrations further into bones of the inner ear.
What is the function of the eustachian tube quizlet?
WHAT IS THE FUNCTION OF THE EUSTACHIAN TUBE? enables air pressure to be equalized between the outside air and the middle ear cavity. snail shell shaped organ which transfers sound vibration into nerve impulses.
What is the tympanic membrane made of?
What is the function of the vestibular membrane?
It primarily functions as a diffusion barrier, allowing nutrients to travel from the perilymph to the endolymph of the membranous labyrinth. Histologically, the membrane is composed of two layers of flattened epithelium, separated by a basal lamina.
How does the basilar membrane discriminate among different sound frequencies?
What happens to the hair cells when the basilar membrane vibrates?
When sound-induced basilar membrane vibrations deflect hair bundles of the outer hair cells, mechanoelectrical transduction of these cells generates the receptor potential (Dallos et al., 1982; Russell and Sellick, 1983).
How does the basilar membrane allows us to differentiate sounds of different pitch?
Explain how the basilar membrane allows us to differentiate sounds of different pitch. Through the movement of the inner vs. … The endolymph flows past the ampullary cupula, pushing it in opposite direction of body movement and causing hair cells to bend and depolarize.
Where is the basilar membrane most sensitive to the vibrations of low frequency sound waves quizlet?
Where is the basal membrane most sensitive to the vibrations of low-frequency sound waves? at the apex, farthest from the oval window.
Outer hair cells are stimulated by the basilar membrane to depolarise, but this causes (as well as APs) the cell to contract. … In hearing, stereocilia 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 ear flap do?
The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to the tympanic membrane (eardrum) [3].
What passes the vibration from the eardrum to the cochlea?
The eardrum vibrations caused by sound waves move the chain of tiny bones (the ossicles – malleus, incus and stapes) in the middle ear transferring the sound vibrations into the cochlea of the inner ear.
What do hair cells line the surface of?
The hair cells that line the inner ear and take part in the process of hearing can be irreversibly damaged by excessive noise levels. Intense sound blasts can rupture the tympanic membrane and dislocate or fracture the small bones of the middle ear.
What kind of stimulus causes the basilar membrane close to the base or oval window of the cochlea to vibrate?
How does the basilar membrane turn sound frequency into a place code?
The cochlea in the inner ear performs a frequency-to-place conversion. A specific point on the basilar membrane inside the cochlear is excited, depending on the frequency of the incoming signal. The movement of the basilar membrane stimulates the hair cells which are connected to the auditory nerve fibers.
What is the difference between the basilar membrane and the tectorial membrane?
What does damage to the basilar membrane cause?
html. Hair cells are sensory receptor cells for hearing and are the structures most easily damaged by sound. … This creates a differential motion between the basilar and tectorial membranes, causing the hair cell stereocilia to bend.
What kind of receptor are the hair cells on the basilar membrane quizlet?
The hearing receptors, called hair cells, are embedded in the tectorial membrane and connected to the basilar membrane by supporting cells. As sound waves cause the basilar membrane to vibrate, the hair cells are bent by the stationary tectorial membrane.
Why is Tonotopic organization important?
The experiments demonstrate that tonotopic representation is crucial to complex pitch perception and provide a new tool in the search for the neural basis of pitch. … Temporal models of pitch perception are attractive for at least two reasons.
What is the tympanic membrane quizlet?
Tympanic Membrane (Eardrum) A thin, membranous partition that separates the external and middle ears. Sound vibrations funneled through the external auditory canal cause the tympanic membrane to vibrate. Function of the eardrum is to carry sound waves to bones that are located in the middle ear.
What does the external acoustic meatus do?
The external acoustic meatus conducts sound waves to the tympanic membrane.
What is the function of the external ear quizlet?
Responsible for gathering sounds from the acoustical environment and funneling them into the auditory mechanism.
What is the primary function of the Eustachian tube?
This air-containing space is maintained by the Eustachian tube, which opens intermittently to equalize the intratympanic air pressure with the pressure in the external auditory canal. It also removes secretion and epithelial debris from the middle ear by ciliary motion and gravity.
