(A) round window
(B) oval window
(C) helicotrema
(D) endolymphatic sac

Answer 1

The communication between the scala vestibuli and scala tympani occurs at the round window.

Step-by-step explanation:

The communication between the scala vestibuli and scala tympani occurs at the round window. The scala vestibuli starts at the oval window and travels above the cochlear duct, while the scala tympani returns to the base of the cochlea, travelling under the cochlear duct. The scala tympani ends at the round window, which is covered by a membrane that contains the fluid within the scala.
