TEMPORAL BONE ANATOMY THE AUDITORY SYSTEM IS DISPOSED ON TWO AXES. The middle ear takes up the space behind the tympanic membrane inside the temporal bone. The eardrum or the tympanic membrane serves as a wall that separates the inner ear and outer ear.

It is separated from the external ear by the tympanic membrane and from the inner ear by the medial wall of the tympanic cavity. It is also membrane-lined interplanetary cavity situated between the Ear Canal and the Eustachian Tube Cochlea and Auditory Nerve. Parts The cavity of the middle ear can be subdivided into the tympanic cavity proper which is opposite the tympanic membrane.

Medial to the tympanic membrane is the tympanic cavity which essentially makes up the middle ear.

The middle ears location directly behind the eardrum or tympanic membrane makes direct non-invasive assessments challenging and limited.

The space is called the tympanic cavity and it has two parts. The area of the middle ear is found immediately after the outer ears ear canal. The middle ear is a narrow air-filled situated in the petrous part of the temporal bone between the external ear and the internal ear.
