  • Paint-filled membranous labyrinths of Otx1 −/ − mutants showed an absence of the lateral semicircular canal, lateral ampulla, utriculosaccular duct and cochleosaccular duct, and a poorly defined hook (the proximal part) of the cochlea. (biologists.com)
  • The stria vascularis is a nonsensory structure that is essential for auditory hair cell function by maintaining potassium concentration of the scala media. (jneurosci.org)
  • The utricular division of the auditory vesicle also responds to angular acceleration, as well as the endolymphatic sac and duct that connect the saccule and utricle. (medscape.com)
  • It is secreted by the secretory cells of the stria vascularis of the cochlea and by the dark cells (present in the utricle and near the ampullated ends of semicircular ducts). (medicoapps.org)
  • High in K + and low in Na + , it is generated and maintained largely by marginal cells of the stria vascularis in the cochlea and dark cells of the vestibular system in the mammalian ear. (biologists.com)
