Exempel på hur man kan använda AMPULLARIS i en mening

• Stimulation of the semicircular canals occurs when the movement of the endolymph inside the canals causes movement of the crista ampullaris and the hair cells within them.
• These include hair cells of the cristae ampullaris of the semicircular duct, and the maculae of the utricle and saccule.
• Part of the crista ampullaris, the cupula has embedded within it hair cells that have several stereocilia associated with each kinocilium.
• Unlike the hair cells of the crista ampullaris or the maculae of the saccule and utricle, hair cells of the cochlear duct do not possess kinocilia.
• Upon angular acceleration (rotation), the endolymph within the semicircular duct deflects the cupula against the hair cells of the crista ampullaris.
• This includes ~7,000 hair cells from each of the semicircular canals located within the crista ampullaris, ~30,000 hair cells from the utricle, and ~16,000 hair cells from the saccule.
• By RNA in-situ hybridization, Sobp expression in neonatal tissue was demonstrated in spiral ganglion, the sensory and supporting cells of the maculae of saccule and maculae of utricle, and cristae ampullaris.
• An acidophyllic mucopolysaccharide-containing substance was discovered, especially in cochleas, maculas, and crista ampullaris of patients with DFNA9 (a chromosome locus), as well as severe degeneration of vestibular and cochlear sensory axons and dendrites.
• Morphological and immunohistochemical studies in several species have indicated that these dark cell areas also form a single layer resting on top of pigmented cells at the base of the cristae ampullaris in the semi-circular canals and around the utricular macula.
