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.
A bony casing houses a complex system of membranous cells. The inner ear is called the labyrinth because of its complex shape. There are two main sections within the inner ear: the bony labyrinth and the membranous labyrinth. The cochlea, the hearing organ, is located inside the inner ear. The snail-like cochlea is made up of three fluid-filled chambers that spiral around a bony core, which contains a central channel called the cochlear duct. Inside the cochlear duct is the main hearing organ, the spiral shaped organ of Corti.
