Dear student,
Membranous labyrinth is filled with endolymph and it contains tubes and chambers which contain the receptors for the senses of equilibrium and hearing.
It contains two membranous sacs -Utricle and Saccule.

Scala tympani is cavity filled with perilymph in the inner ear .
It is separated from the cochlear duct by basilar membrane and it extends from the round window to helicotrema and continues as 
vestibular duct.

Scala vestibuli is a perilymph  filled cavity in the cochlea of inner ear that transmits sound vibrations to cochlear duct.

These two are not a part of Membranous labyrinth.
