Some of the middle ear structures may be seen through an especially transparent ear drum, while the inner ear may be evaluated only by CT scans, MRI scans or indirectly by special testing, such as audiometry (hearing tests) or other special tests of inner ear function.
Your ears are not just for hearing â they are also important for controlling position sense and balance. Each ear is divided into 3 sections: the outer; middle; and inner ear. The middle and inner parts of the ear are located in hollow cavities on either side of the head within the temporal bones of the skull. The outer ear. The external part of your ear consists of the pinna and ear lobe. The pinna is the shell-like part of your external ear, and is made of cartilage and skin. It directs sound waves from the outside into your external auditory canal (ear canal), which in turn channels sound waves to the tympanic membrane (also known as the ear drum). The tympanic membrane is a thin, semi-transparent membrane that separates the outer and middle ear.
