WebbWhile hair bundles of inner hair cells are of linear shape, those of outer hair cells exhibit a distinctive V-shape. The biophysical rationale behind this morphology, however, remains unknown. Here we use analytical and computational methods to study the fluid flow across rows of differently shaped hair bundles. WebbSee Page 1. 69.Assound levelsincrease inthespiral organEofCorti),. a.

Here, the stereocilia are all oriented in the same direction. In the otoliths, the hair cells are … WebbThe outer hair cells are active. They move in response to sound and amplify the traveling wave. The outer hair cells also produce sounds that can be detected in the external auditory meatus with sensitive microphones. These internally generated sounds, termed otoacoustic emissions, are now used to screen newborns for hearing loss. shuttles slc to park city
