15 March 2016 â¢ 2:25pm. The death of an American tourist in a horrific lion attack in South Africa in the summer of 2015 was a stark reminder of the dangers that can be posed by wildlife.

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.
Middle ear. The cavity or space between the eardrum and the inner ear. It includes the eardrum, the three little bones (hammer, anvil, and stirrup) that transmit sound to the inner ear, and the eustachian tube, which connects the inner ear to the nasopharynx (the back of the nose).t is separated from the external ear by the tympanic membrane and from the inner ear by the oval window. The auditory (eustachian) tube carries air from the posterior nasopharynx into the middle ear. Also called tympanic cavity. Compare external ear, internal ear.
