(A) The inner ear, or labyrinth, consists of a bony labyrinth and a membranous labyrinth.The bony labyrinth is a series of channels filled with a fluid called perilymph.The membranous labyrinth is suspended within the bony labyrinth and is filled with a fluid called endolymph.The cochlea is the coiled portion of the labyrinth. It is divided into three chambers by the Reissner's membrane and the basilar membrane:$1$. The upper chamber is the $Scala 	ext{ } vestibuli$, which is filled with perilymph.$2$. The middle chamber is the $Scala 	ext{ } media$, which is filled with endolymph.$3$. The lower chamber is the $Scala 	ext{ } tympani$, which is filled with perilymph.Therefore, the correct sequence is perilymph, endolymph, and perilymph.
