Life Sentence The wave, however, is not merely a movement of the basilar membrane, but an actual movement of fluid or a transmission of pressure. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z A sound wave sets your eardrum vibrating, which ultimately causes a spiraling membrane within the inner ear called the basilar membrane to vibrate, too. How the Ear Distinguishes Sweet Sounds From Sour Notes 2011-09-09T20:39:36Z The hair cells are arranged on the basilar membrane in an orderly way. Biology for AP Courses 2022-06-09T00:00:00Z Figure 14.9 The basilar membrane is the thin membrane that extends from the central core of the cochlea to the edge. Anatomy and Physiology 2013-06-19T00:00:00Z Periopticon: a complex nerve structure back of the basilar membrane of the eye. Explanation of Terms Used in Entomology With each maximum and minimum different parts of the basilar membrane are affected, and affected a different number of times per second, according to the frequencies of the partials existing in the compound tone. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z The nerve fibers terminate upon the membrane known as the basilar membrane, which separates it from the scala tympani. Physiology and Hygiene for Secondary Schools The basilar membrane vibrates in different regions, according to the frequency of the sound waves impinging on it. Biology for AP Courses 2022-06-09T00:00:00Z Lower frequency waves move the region of the basilar membrane that is near the tip of the cochlea. Anatomy and Physiology 2013-06-19T00:00:00Z It consists essentially of modified ephithelial cells floated upon the auditory epithelium, or basilar membrane, of the cochlea. A Practical Physiology He supposes that with each movement of the stapes corresponding to a vibration, a wave travels up the scala vestibuli, pressing the basilar membrane downwards. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z From here the vibrations pass through the channels of the cochlea and set into vibration the contents of the scala media and different portions of the basilar membrane. Physiology and Hygiene for Secondary Schools When sound waves produce fluid waves inside the cochlea, the basilar membrane flexes, bending the stereocilia that attach to the tectorial membrane. Biology for AP Courses 2022-06-09T00:00:00Z Protein fibers tether adjacent hairs together within each array, such that the array will bend in response to movements of the basilar membrane. Anatomy and Physiology 2013-06-19T00:00:00Z It is estimated that there are no less than 3000 of these arches in the human ear, placed side by side in a continuous series along the whole length of the basilar membrane. A Practical Physiology It would appear also that the filaments of the auditory nerve terminate in the basilar membrane, and possibly they may be connected with the hair-cells. Encyclopaedia Britannica, 11th Edition, Volume 13, Slice 2 "Hearing" to "Helmond" 2012-04-25T02:00:53.567Z The basilar membrane, while continuous throughout, may be regarded as made up of many separate cords of different lengths stretched side by side. Physiology and Hygiene for Secondary Schools Inside the cochlea, the basilar membrane is a mechanical analyzer that runs the length of the cochlea, curling toward the cochlea’s center. Biology for AP Courses 2022-06-09T00:00:00Z 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. Anatomy and Physiology 2013-06-19T00:00:00Z Physiologically, one or more basilar membrane fibres are excited by both, and this fact gives the positive feeling of relationship or consonance. The Psychology of Beauty Once in the cochlea, the energy causes the basilar membrane to flex, thereby bending the stereocilia on receptor hair cells. Biology for AP Courses 2022-06-09T00:00:00Z Another theory is that the basilar membrane responds to all kinds of vibrations and the analysis of sound takes place in the brain. Physiology and Hygiene for Secondary Schools Different regions of the basilar membrane vibrate according to the frequency of the sound wave conducted through the fluid in the cochlea. Biology for AP Courses 2022-06-09T00:00:00Z Specific wavelengths of sound cause specific regions of the basilar membrane to vibrate, much like the keys of a piano produce sound at different frequencies. Anatomy and Physiology 2013-06-19T00:00:00Z The organ of Corti, containing the mechanoreceptor hair cells, is adjacent to the scala tympani, where it sits atop the basilar membrane. Anatomy and Physiology 2013-06-19T00:00:00Z Figure 14.10 Frequency Coding in the Cochlea The standing sound wave generated in the cochlea by the movement of the oval window deflects the basilar membrane on the basis of the frequency of sound. Anatomy and Physiology 2013-06-19T00:00:00Z A third view is that the filaments from the hair cells, rather than the basilar membrane, respond to the vibrations and in turn stimulate the terminations of the nerve fibers. Physiology and Hygiene for Secondary Schools It is composed of hair cells held in place above the basilar membrane like flowers projecting up from soil, with their exposed short, hair-like stereocilia contacting or embedded in the tectorial membrane above them. Biology for AP Courses 2022-06-09T00:00:00Z Higher frequency waves move the region of the basilar membrane that is close to the base of the cochlea. Anatomy and Physiology 2013-06-19T00:00:00Z Trace a sound wave from a bell to the basilar membrane, and trace the impulse that it causes from there to the brain. Physiology and Hygiene for Secondary Schools The rods of Corti are thought to act as dampers on the basilar membrane, to prevent the continuance of vibrations when once they are started.
