183. Damage to the hair cells lining the basilar membrane is most likely to result in A) phantom limb sensations. B) conduction hearing loss. C) loss of the sense of balance. D) sensorineural hearing loss. 184. As a rock musician who has experienced prolonged exposure to high-amplitude sounds, Rodney is beginning to lose his hearing. It is most likely that this hearing loss involves problems. Answer: b. audition. Explanation: Basilar membrane: The term basilar membrane is determined as one of the stiff structural element that is being found in the cochlea of an individual's inner ear that generally separates or splits-up two different tubes filled with liquid and therefore runs along with the coil of the scala media, the cochlea, and the scala tympani There are both external causes of damage, including infection, and ototoxic drugs, as well as intrinsic causes, including genetic mutations. A common cause or exacerbating factor in SNHL is prolonged exposure to environmental noise, or noise-induced hearing loss Outer hair cells also substantially improve the frequency selectivity of the basilar membrane (the ability to separate complex sounds into their constituent frequencies). Outer hair cell dysfunction therefore also results in a reduction in the sharpness of basilar membrane tuning (Ruggero and Rich, 1991). View chapter Purchase boo

Damage of the basilar membrane by acoustic stimulation

This partition is called the basilar membrane because it serves as the base, or ground floor, on which key hearing structures sit. Once the vibrations cause the fluid inside the cochlea to ripple, a traveling wave forms along the basilar membrane. Hair cells-sensory cells sitting on top of the basilar membrane-ride the wave Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti. What happens if the cochlea is damaged? It is the main organ of hearing and is part of your inner ear. Cochlear Damage means that all or part of your inner ear has been hurt. Damage to the cochlea typically causes permanent. c. prevents damage to delicate ear structures. d. involves the scala vestibuli and the scala tympani. e. vibrates the tympanic membrane. The correct answer is: prevents damage to delicate ear structures. The round window Select one: a. reflects sound waves. b. vibrates the basilar membrane. c. allows for compression of the organ of Corti. d The upper and lower parts of the cochlea are separated by an elastic, basilar membrane that serves as the base, or ground floor, upon which key hearing structures sit. Incoming sound vibrations cause the fluid inside the cochlea to ripple, and a traveling wave forms along the basilar membrane Previous basilar membrane stiffness measurements. The mechanical properties of cochlear tissues were first measured by von Békésy (), who reported that the elasticity of the cochlear partition changed by a factor of 100 from the base to the apex of the 35-mm-long human cadaver cochlea.Despite the basic concerns regarding the freshness of his cadaver preparations (e.g., see Vôldrich 1978.

Other articles where Basilar membrane is discussed: senses: Mechanical senses: long membrane, known as the basilar membrane, which is tuned in such a way that high tones vibrate the region near the base and low tones vibrate the region near the apex. Sitting on the basilar membrane is the organ of Corti, an array of hair cells with stereocilia tha Movement of the basilar membrane in response to sound waves causes the depolarization of hair cells in the organ of Corti. What type of hearing loss may result from infection or trauma? Head trauma, ear infections, tumors and toxic medications such as certain strong antibiotics and chemotherapeutics are other reasons for sensorineural hearing loss 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.The basilar membrane moves up and down in response to incoming sound waves, which are converted to traveling waves on the basilar membrane By perturbing amplification in narrow segments of the basilar membrane, we further show that a cochlear traveling wave accumulates gain as it approaches its peak. Analysis of these results indicates that cochlear amplification produces negative damping that counters the viscous drag impeding traveling waves; targeted photoinactivation locally. This process occurs, however, only at the inner ear or cochlear level. In rate coding, low frequency sounds are encoded when neurons fire in synchrony with movement of the apical end of the basilar membrane. Bilateral damage to the auditory cortex is not associated with permanent deficits in the ability to detect sound

Cochleostomy Site: Implications for Electrode Placement

  1. More specifically, the base of the basilar membrane responds best to high frequencies and the tip of the basilar membrane responds best to low frequencies. Therefore, hair cells that are in the base portion would be labeled as high-pitch receptors, while those in the tip of basilar membrane would be labeled as low-pitch receptors (Shamma, 2001.
  2. The basilar membrane is the narrowest (0.08-0.16 mm) and most stiff at the base of the cochlea, and the widest (0.42-0.65 mm) and least stiff at the apex. Note that low-frequency sounds localize near the apex of the cochlea, while high-frequency sounds localize near the base. This sort of non-uniformity in the structure of the basilar membrane.
  3. The interpretation is that as the tip of the electrode bends the shaft can move in the mediolateral dimension, sometimes contacting the basilar membrane and sometimes not. Overall, the results indicate that recordings during cochlear implantations can provide valuable feedback to the surgeon regarding electrode position and the integrity of.

Apart from a lifted basilar membrane, no serious damage was found even when applying two different techniques as done in series A and B. The modiolus, which is very closely related to the electrode, remained unaffected. The results of our study also confirm the findings of [4, 11,. Transcribed image text: Question 7 10 pts Due to a freak explosion at the tuning fork factory, a patient has very selective damage to her basilar membrane's hair cells that encode 220 Hz. The audiologist confirms this with a test where al series of pure tones are played over headphones at different loudnesses Regarding endolymphatic hydrops, an overproduction of endolymph results in a widening of the scala media and a shift of the basilar membrane. Consequently, this has a negative effect on the hair cells that sit on the basilar membrane, leading to hearing loss and ringing in the ears (tinnitus) that magnetic steering, of sufficient magnitude, significantly reduces forces on the basilar membrane for insertion depths beyond 14.4mm, which includes the critical region in which damage to the basilar membrane most commonly occurs. This study provides compelling evidence that magnetic steering of robotically inserted electrode arrays wil The scala tympani and cochlear duct are separated by the basilar membrane. As previously mentioned sensory hearing loss results from damaged hair cells while central hearing loss can be the result of damage to the auditory nerve pathway..

  1. Damage to the basilar membrane impairs hearing. More specifically, damage to cilia cells (tiny hairs within the B.M.) corresponding to the frequency of a sound result in the impairment of ones.
  2. CONCLUSION: Results from this study are useful for cochlear implant surgeons in better understanding the mechanism of damage by the electrode array's proximal section to the basilar membrane and in establishing advanced insertion techniques for reducing the damage (in particular, the results strongly support the advance off-stylet technique)
  3. g 2 long chambers connected together by an opening at the far end called the helicotrema . * ~ 15000 hair cells (connected to ~ 30,000 nerve fibers embedded in the basilar membrane

Basilar membrane vibration causes stereocilia deflection. In both types of hair cells, the mechanical stimulus is transduced and receptor potentials are generated. In IHCs, this leads to neurotransmitter release and AP generation in underlying auditory nerve fibres. However, in OHCs, receptor potentials result in contraction, which amplifies. 5. basilar membrane fibers of different length, thickness, and tension like strings of a 2. damage to vestibulocochlear nerve (VIII) 3. damage to nuclei/tracts to the cortex D. Menierre's Syndrome - effects both hearing and balance; results in tinnitus, vertigo, and. interspersed nausea and vomiting. 1. may be too much endolymph. We propose that this is the result of the physical characteristics of the basilar membrane. At the cochlear base, where higher frequencies are transduced, the basilar membrane is narrow, thick, and stiff, and therefore resistant to pressure changes that are not in its resonant frequency range ( fig. 3 ) Damaged Hair Cells & HearingLoss Effects of Outer Hair Cell DamageOuter hair cell damage results in themost common type of hearing loss—amoderate sensorineural hearing losswhere soft sounds below conversationalspeech are inaudible—yet loud soundsare perceived as loud—just as theywould to someone with normal hearing. 5 Each auditory nerve fiber is connected to a small number of hair cells, near one another, on the basilar membrane. The nerve fiber's response is governed, therefore, by the motion of a small region of the basilar membrane. And the basilar membrane in any small region undergoes its largest motion only for a limited range of frequencies

The basilar membrane #EAR-1 View Image extends from the tip of the osseous spiral lamina of the central modiolus to the outer wall of the cochlea and separates the cochlear duct from the scala tympani. The organ of Corti rests on the basilar membrane. Damage to the eardrum or ossicles results in so-called conduction deafness whereby sound. Because the tectorial membrane only moves where the basilar membrane moves, the hair cells in this region will also only respond to sounds of this specific frequency. Therefore, as the frequency of a sound changes, different hair cells are activated all along the basilar membrane The basilar membrane distributes vibrations to hair cells. The motion of the fluid in the cochlear tubes sets the basilar membrane in motion, generating traveling waves along its length. These are somewhat like the waves produced in a long rope that is grasped at one end and flicked. The second results when damage occurs to the inner ear. Riding on the vibrating basilar membrane are hair cells topped with microscopic bundles of hairlike stereocilia, which are deflected by the overlying tectorial membrane. Hair cells convert the mechanical vibration to electrical signals, which in turn excite the 30,000 fibers of the auditory nerve

A basilar skull fracture that occurs around the opening in the base of the skull where the spinal cord attaches to the brain can cause damage to the surrounding nerves and blood vessels. Damage to these nerves or other nerves in the face can result in temporary or permanent paralysis of facial muscles and the muscles around the eyes As a result, the hair cell membrane is depolarized, and a signal is transmitted to the chochlear nerve. 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 Fig. 1. Sound-evoked movements of the lateral segment of the basilar membrane are small in isolated preparations.

Damage to the basilar membrane is most likely to result in A) loss of movement. B) accommodation. C) conduction hearing loss. D) loss of the sense of balance Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent Tectorial membrane, which runs parallel to the basilar membrane, is less flexible and doesn't move when basilar membrane moves. Hairs of hair cells are sandwiched between the two membranes, so they bend when the basilar membrane moves toward the tectorial membrane, causing tiny channels to open up in the hair cell's membrane, which changes.
