perilymphatic ducts 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.
