perilymphatic duct การใช้

• CSF pressure abnormalities do not generally have clinical impact on the inner ear which is explained physically by the bore diameter of the perilymphatic duct and its length.
• There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphatic duct where the perilymph is continuous with the cerebrospinal fluid.
• In most reptiles the perilymphatic duct and lagena are relatively short, and the sensory cells are confined to a small "'basilar papilla "'lying between them.
• In the anatomy of the human ear, the "'perilymphatic duct "'is where the perilymphatic space ( i . e ., the vestibule of the inner ear ) is connected to the subarachnoid space.
• Later temnospondyls like " Doleserpeton " had otic regions adapted to hearing . " Doleserpeton " has a structure in the inner ear called the perilymphatic duct, which is also seen in frogs and is associated with hearing.
• Perilymph is the fluid contained within the bony labyrinth, surrounding and protecting the membranous labyrinth; perilymph resembles extracellular fluid in composition ( sodium salts are the predominate positive electrolyte ) and, via the perilymphatic duct, is in continuity with cerebrospinal fluid.
