Perilymph is normally found in which part of the inner ear?

Explanation:
Perilymph is the fluid of the bony labyrinth and surrounds the membranous labyrinth. In the cochlea, perilymph fills the scala vestibuli and the scala tympani, while endolymph is confined to the scala media (cochlear duct). The scala tympani is the lower chamber that ends at the round window and is lined with perilymph. Therefore, perilymph is normally found in the scala tympani.
