This seems to increase bundle sturdiness and prevent the splaying of the stereocilia that can occur with repeated acoustic insults.

Stereocilia are composed of cytoplasm with embedded bundles of cross-linked actin filaments. The actin filaments anchor to the terminal web and the top of the cell membrane and are arranged in grade of height. [2] As sound waves propagate in the cochlea, the movement of endolymph fluid bends the stereocilia. 查看更多內容 In the inner ear, stereocilia are the mechanosensing organelles of hair cells, which respond to fluid motion in numerous types of animals for various functions, including hearing and balance. They are about 10–50 查看更多內容 As acoustic sensors in mammals, stereocilia are lined up in the organ of Corti within the cochlea of the inner ear. In hearing, stereocilia transform the mechanical energy of sound waves into electrical signals for the hair cells, which ultimately leads … 查看更多內容 In the cochlea, a shearing movement between the tectorial membrane and the basilar membrane deflects the stereocilia, affecting the tension on the tip-link filaments, which … 查看更多內容 The methionine sulfoxide reductase B3 gene (MsrB3), a protein repair enzyme, has been implicated in large scale stereocilia bundle degeneration, as well as many other … 查看更多內容 Resembling hair-like projections, the stereocilia are arranged in bundles of 30-300. Within the bundles the stereocilia are often lined up in several rows of increasing height, similar to a staircase. At the core of these hair-like stereocilia are rigid cross-linked 查看更多內容 In the vestibular system, the stereocilia are located in the otolithic organs and the semicircular canals. Hair cells in the vestibular … 查看更多內容 Stereocilia (along with the entirety of the hair cell) in mammals can be damaged or destroyed by excessive loud noises, disease, and toxins and are not regenerable. 查看更多內容網頁2007年6月1日 · Planar cell polarity (PCP) refers to the polarization of cells within the plane of a cell sheet.
