Which Chamber of the Inner Ear Receives Sound Waves Directly

Question

Which chamber of the inner ear receives sound waves directly from the oval window?
A)Cochlear duct
B)Scala media
C)Scala tympani
D)Vestibule
E)Scala vestibuli

Accepted Answer

The Scala vestibuli is the chamber that receives sound waves directly from the oval window. This is the first chamber in the cochlea that sound waves encounter as they travel through the inner ear. The other chambers in the cochlea include the Scala media (containing the organ of Corti), and the Scala tympani (which terminates at the round window). The vestibule is not part of the cochlea, but is located adjacent to it and is responsible for detecting linear acceleration and head position.
