scala mediaの例文

• The fluid found in these two cochlear chambers is perilymph, while scala media, or the cochlear duct, is filled with endolymph.
• The organ of Corti forms a ribbon of sensory epithelium which runs lengthwise down the cochlea's entire " scala media ".
• As the cochlear duct s mesenchyme begins to differentiate, three cavities are formed : the scala vestibuli, the scala tympani and the scala media.
• A cross section of the cochlea will reveal an anatomical structure with three main chambers ( scala vestibuli, scala media, and scala tympani ).
• The perilymph that is found in the scala tympani has a low potassium concentration, whereas the endolymph found in the scala media has a high potassium concentration and an electrical potential of about 80 millivolts compared to the perilymph.
• With the movement of the basilar membrane, a shear force is created and a small potential is generated due to a difference in potential between the endolymph ( scala media-+ 80 mV ) and the perilymph ( vestibular and tympanic ducts-- 70 mV ).
• This separation is the main function of Reissner's membrane ( between scala vestibuli and scala media ), and it is also the function of tissue held by the basilar membrane such as the inner and outer sulcus cells ( shown in yellow ) and the reticular lamina of the organ of Corti ( shown in magenta ).
