Enervated by the spiral ganglion, its namesake duct connects to the canal of Henson.  Reissner's membrane, which separates the scala media from the scala vestibule, forms an endolymph-filled compartment in this organ along with the basilar membrane.  The helicotrema connects the scala vestibule and the scala tympani, while vibrations are sent to it via the stapes.  Containing the organ of Corti, FTP, identify this organ of the inner ear that takes its name from its snail-like shape.
