The central cavity of the ear is called the: a. tympani, which is a latin word that means"hollow" b. concha, which is a greek word that means"shell" c. pinna, which is a greek word that means"flap" d. fossa, which is a latin word that means"hole"

If I'm honest this is more of science question then a English question, but I can see why it could be a English question.

D. is a possible answer, but no. Fossa is like a shallow hole, and that could work, but that is not what the central cavity of a ear is called.

C. Pinna is a part of the ear, but not the central cavity! A Pinna is auricle, the external part of the ear.

B. This is a also answer put in to throw you off. Concha means shell yes and is also part of the ear, but not the central cavity. The Concha is the part leading up to the central cavity.

A. Is your answer. I hope that helps you out!
