epitympanum
Quick Summary
The epitympanum is the upper chamber of the middle ear, also known as the attic. It is separated from the brain by a thin plate of bone. This space is crucial for hearing as it houses part of the ossicular chain, specifically the head of the malleus and the body of the incus. These tiny bones transmit sound vibrations from the tympanic membrane to the inner ear, playing a vital role in our ability to perceive sound. The epitympanum is connected to the lower chamber, the tympanum, and is bordered by the mastoid antrum and the inner ear.12
