The outer hair cells
Webb10 okt. 2024 · Short answer. Outer hair cells physically contract at a rate corresponding to the characteristic resonant frequency at which they are situated on the basilar … 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.

The tereocilia of the outer hair cells are linked to the tectorial membrane, which is a gelatinous layer that sits atop the basilar membrane of the cochlea. The basilar membrane is the outermost layer of the cochlea. Incoming sound waves cause the basilar membrane to vibrate, and this vibration is communicated to the tectorial membrane. smallest country in saarcWebbThe outer hair cells (OHCs) can amplify the signal through a process called electromotility where they increase movement of the basilar and tectorial membranes and therefore … song keeper of the stars youtube
