Endolymph is the fluid inside which inner-ear compartment?

Explanation:
Endolymph resides inside the membranous labyrinth, the interconnected system of fluid-filled sacs and ducts within the inner ear. This membranous network sits inside the bony labyrinth and is separated from it by the perilymph-filled perilymphatic space. The endolymphatic fluid bathes the sensory hair cells throughout all parts of the membranous labyrinth, including the cochlear duct in the cochlea and the semicircular ducts, utricle, and saccule in the vestibular apparatus. Endolymph has a distinctive high potassium content, which is essential for the transduction of mechanical signals into neural signals. So, the fluid in question is endolymph located within the membranous labyrinth.
