The mammalian ear has three sections; (I) The outer ear (II) The middle ear (III) The inner ear

(A) Outer ear: The outer ear is made up of the pinna which leads to an ear canal. The ear canal is made up by fine hair as well as oils made by special glands. (B) Middle ear: The middle ear contains three tiny bones called ossicles that joins with one another and form a bridge across the middle ear. A second opening covered by a membrane, connects the middle ear with the inner ear. (C) Inner ear: The inner ear consists of bony canals filled with a fluid called perilymph. Another aspects of it is called the endolymph. Both are called the bony labyrinth. The two systems contain two important sensory structures.
