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. But while terrifying, attacks by lions on humans are quite rare. Fewer than 100 people are killed by lions each year.
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.
The anatomy of the ear can be a little confusing, especially since the ear is responsible not only for hearing, but also for balance. There are three components to the ear: the outer ear, the middle ear and the inner ear. All three are involved in hearing but only the inner ear is responsible for balance.The outer ear is composed of the pinna, or ear lobe, and the external auditory canal.Both structures funnel sound waves towards the ear drum or tympanic membrane allowing it to vibrate. The pinna is also responsible for protecting the ear drum from damage. Modified sweat glands in the ear canal form ear wax.he anatomy of the ear can be a little confusing, especially since the ear is responsible not only for hearing, but also for balance.
