Vedclass · Answer

(B) The inner ear consists of a bony labyrinth filled with perilymph and a membranous labyrinth filled with endolymph.$Scala 	ext{ } vestibuli$ ends at the oval window, while the $Scala 	ext{ } tympani$ terminates at the round window (fenestra rotunda).The round window is a membrane-covered opening that separates the middle ear cavity from the inner ear.Therefore, $A$ is the round window and $B$ is the middle ear.

The $Scala \text{ } tympani$ of the membranous labyrinth ends at $A$, which opens into $B$. Identify $A$ and $B$ and select the correct option.
