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.
DEAR READER: Your eardrum is a thin membrane involved in hearing. It separates your ear canal (the part that is open to the outside) from your middle ear. The outer, middle, and inner ear. The outer ear consists of the parts you can see: the fleshy outer part (called the auricle), the ear canal, and the eardrum. The middle ear is an air-filled cavity containing the ossicles, three small bones (malleus, incus, and stapes) that transmit vibrations to the inner ear.
