What structure is NOT found in the inner ear?

The Eustachian tube is not a structure found in the inner ear; instead, it connects the middle ear to the nasopharynx and helps equalize pressure in the middle ear. In contrast, the inner ear contains the cochlea, which is crucial for hearing, as it converts sound vibrations into electrical signals sent to the brain. It also houses balance structures such as the vestibule and semicircular canals, which are essential for maintaining equilibrium. The auditory nerve carries the signals from the cochlea to the brain for interpretation. Understanding the distinct functions of these structures clarifies their locations within the ear's anatomy.
