What are the key evolutionary innovations in the structure and function of hair cells and stereocilia?

May 21, 2018 ... These tiny fibers form bundles sitting atop sensory hair cells deep inside your inner ear, and give them their name. Stereocilia are as ... These results provide the first direct evidence that type I hair cells have significantly more stereocilia than type II hair cells. When your head moves, the endolymph moves the cupula and stimulates the stereocilia. Vertigo is a feeling of dizziness or sudden sensation of spinning when ... Deflection of the bundle of stereocilia is mechanically responsible for stretching ion pores in the stereocilia, allowing a cation current to pass into the cell ... Male Smpx null mice showed a progressive hearing loss starting from high frequency at the 3rd month. Hearing loss in female mice was milder and occurred later. ... stereocilia; GZ, Golgi zone; NF, not found; GalTase, galactosyltransferase; α-SMA, alpha smooth muscle actin; Cx43, connexin-43; BP, basal part; VEGF ... May 10, 2021 ... We show that IHC and OHC stereocilia are similarly TM-embedded and that Ca 2+ ducts connect the TM to the stereocilia of IHCs and OHCs. Mar 27, 2024 ... Stereocilia ... Structures and types of simple epithelia. ... Stereocilia are cylindrical immotile microvilli found on the apical surfaces of ... Apr 13, 2017 ... Because the actin filaments in the stereocilia of hair borders still remain as compact bun- dles, albeit very disordered, there must be an addi-. ... stereocilia functional architecture and self-renewal.
