What induces ripple in basilar membrane?
Nerve impulses are generated in the associated afferent neurons iii. The waves in the lymphs induce a ripple in the basilar membrane iv. The vibrations are passed to the fluid of the cochlea, where generate waves in the lymphs.
What stimulates the basilar membrane?
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.
How is the basilar membrane Tonotopically organized?
When very high-frequency sound waves reach the ear, only the region nearest the cochlear base vibrates. As the frequency of the sound is lowered, the place of maximal amplitude of vibration shifts toward the cochlear apex. Because of this resonance gradient, the basilar membrane is said to be “tonotopically” organized.
What is the basilar membrane and why is it important?
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 do different parts of the basilar membrane respond to?
sound waves
The basilar membrane moves up and down in response to incoming sound waves, which are converted to traveling waves on the basilar membrane….Basilar membrane.

What part of the basilar membrane would a low frequency sound stimulate?
apex
(B) High-frequency sound waves cause maximum vibration of the area of the basilar membrane nearest to the base of the cochlea; (C) medium-frequency waves affect the centre of the membrane; (D) and low-frequency waves preferentially stimulate the apex of the basilar membrane.
What does it mean to be to Tonotopically organized?
In physiology, tonotopy (from Greek tono = frequency and topos = place) is the spatial arrangement of where sounds of different frequency are processed in the brain.
What do you mean by basilar membrane?
Definition of basilar membrane : a membrane extending from the bony shelf of the cochlea to the outer wall and supporting 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 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 does the basilar membrane connect to?
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?
The basilar membrane is a resonant structure varying systematically in width and stiffness. It is wider (0.42–0.65 mm) and more flaccid at the cochlear apex than at the base (0.08–0.16 mm). When a sound wave is transmitted to the fluid of the inner ear, the basilar membrane is set in motion.
Why does the basilar membrane present the first level of frequency analysis?
The basilar membrane (BM) presents the first level of frequency analysis in the cochlea because of its changing stiffness and nearly constant unit mass from base to apex. This forms a frequency-tuned delay line.
What are the three Mössbauer parameters?
The three Mössbauer parameters: isomer shift, quadrupole splitting, and hyperfine splitting can often be used to identify a particular compound by comparison to spectra for standards. In some cases, a compound may have more than one possible position for the Mössbauer active atom.
What is the Mössbauer effect?
This effect, discovered by Rudolf Mössbauer (also Moessbauer, German: “Mößbauer”) in 1958, consists in the nearly recoil-free, resonant absorption and emission of gamma rays in solids.
