Stereociliary bundles
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2024年3月7日 · The asymmetric location of stereociliary bundle (hair bundle) on the apical surface of mechanosensory hair cells (HCs) dictates the direction in which a given HC …

網頁1998年8月28日 · To investigate stereocilia motion for physiologically reasonable deflections and frequencies of excitation, the fluid–structure interaction of the stereocilia bundle is considered analytically. Solutions in the frequency domain are determined for stereocilia bundle dimensions at several locations along the cochlear duct of the chinchilla. 網頁2010年5月14日 · We found that the protrusions were labeled with antibodies to cadherin 23 (Figures 5 E and 5F), further indicating that the bundles correspond to immature hair cell stereociliary bundles. The tops of short stereocilia that are connected with tip links to their taller neighbors usually appear to be pointed and asymmetric ( Lin et al., 2005 ), which …
網頁2024年5月7日 · Because the stereociliary bundle is the most sensitive mechanical component of the cochlea, OHC death may be initiated by stereociliary trauma. Scanning electron microscopy of basal OHCs from unexposed control mice ( n = 3) exhibited normal bundle organization ( Fig. 2 M ). 網頁2011年7月21日 · The stereociliary tip links contain the gate cation channels which open during deflection of the hair bundle and allow potassium and calcium to enter via mechanosensitive channels. Reference Beurg, Fettiplace, Nam and Ricci 74 Recent findings suggest that mechanoelectrical transduction channels are localised at the bottom of the …
