swollen and is called ampulla, which contains a projecting ridge caned, within cochlea called scala media is filled with endolymph. At the base of, the cochlea, the scala vestibuli ends at the oval window, while the scala, tympani terminates at the round window which opens to the middle ear, crista ampullaris which has hair cells The saccule and utricle contain a, projecting ridge called macula. The crista and macula are the specific, receptors of the vestibular apparatus responsible for maintenance o, balance of the body and posture., receptors of the vestibular apparatus responsible for maintenance o, projecting ridge called macula. The crista and macula are the specific, crista ampullaris which has hair cells. The saccule and utricle contain a, swollen and is called ampulla, which contains a projecting ridge called, Reissner's membrane, 20.6.2.1, Mechanism of Hearing, How does ear convert sound waves into neural impulses. which, sensed and processed by the brain enabling us to recognise a soun, Scala vestibuli, Scala media, The external ear receives sound waves and directs them to the ear dr, The ear drum vibrates in response to the sound waves and these vibrat, are transmitted through the ear ossicles (malleus, incus and stape, the oval window. The vibrations are passed through the oval windo, to the fluid of the cochlea, where they generate waves in the lymphs, waves in the lymphs induce a ripple in the basilar membrane., Organ of corti, movements of the basilar membrane bend the hair cells, pressing, against the tectorial membrane. As a result, nerve impulses are ger, in the associated afferent neurons. These impulses are transmi, the afferent fibres via auditory nerves to the auditory cortex of the, where the impulses are analysed and the sound is recognised., Tectorial membrane, SUMMARY, The neural system coordinates and integrates funct, and homeostatic activities of all the organs.
