Basement plate

Japanese: 基底板 - きていばん

…It is a plate-like structure that lines the underside of the epithelium that covers the surface of an animal's body. It is often called the basal lamina because it is structurally completely different from the cell membrane and the membrane inside the cell. It is about 500 to 1000 Å thick, contains mucopolysaccharides and collagen fine fibers, and stains black with silver staining and pink with the periodic acid-Schiff reaction (also known as the PAS reaction), which is a method for staining carbohydrates. …

From the ears

…When viewed in cross section, the cochlea is divided into the scala tympani, scala media, and scala vestibuli. The scala vestibular and scala tympani are connected by the cochlear foramen at the top of the cochlea, and contain perilymph. The scala media is also called the cochlear duct, and is surrounded by the vestibular membrane (also called the vestibular membrane wall or Reissner's membrane), the stria vascularis, and the basilar membrane (also called the basilar plate or scala tympani wall), and contains endolymph. The tissue surrounding the endolymph is called the membranous labyrinth. …

…蝸牛の断面をみると鼓室階，中央階，前庭階に分かれており，前庭階と鼓室階は蝸牛の頂上の蝸牛孔でつながっており，内部に外リンパを含む。中央階は蝸牛管ともいい，前庭膜(前庭階壁，ライスネル膜ともいう)，血管条，基底膜(基底板，鼓室階壁ともいう)で囲まれており，内リンパを含む。内リンパを囲む組織を膜迷路という。…
