What are outer hair cells?

The organ of Corti contains tiny hair cells with stereocilia at the ends. Stereocilia are delicate, hair-like projections that react to cochlea fluid movement. For the latter option to work without downtime, each stereocilium (or sets of mechanically-connected stereocilia) must be able to execute the recovery by itself ... Dec 4, 2021 ... The longer stereocilia that project from the outer hair cells actually attach to the tectorial membrane. All of the stereocilia are ... Oct 18, 2022 ... Stereocilia movements create an electrical signal that the auditory nerve carries to the brain. But accurately capturing and interpreting the ... Jun 20, 2019 ... We report that TRIOBP-5 is essential for thickening bundles of F-actin in rootlets, establishing their mature dimensions and for stiffening supporting cells. Nov 3, 2021 ... ... stereocilia. Sound vibrations cause the stereocilia to sway, which leads to the hair cell sending signals to nearby neurons that relay ... Jan 4, 2021 ... show that ADF/cofilin-1 are recruited to mechanotransducing auditory stereocilia tips, where they increase the availability of F-actin barbed. Apr 16, 2025 ... Stereocilia perch atop sensory hair cells in the inner ear. Source: Yoshiyuki Kawashima. Most NIHL is caused by the damage and eventual death of ... The actin filament bundle, which is held together by specific crossbridges, gives rigidity and exact dimensions to each stereocilium. The cuticular plate ... The stereocilia are simpler, containing only an actin cytoskeleton. Each stereocilium tapers where it inserts into the apical membrane, forming a hinge ...
