INTRODUCTION:
The ear perform to sensory functions, hearing and maintenance of body balance. Anatomically the ear can be divided into three major sections called the outer ear, the middle ear and the inner ear.
The outer ear consist of the pinna and external auditory meatus canal.
The Pinna collects the vibrations in the air which produce sound.
The external auditory meatus leads inwards extends up to the tympanic membrane (the ear drum).
There are very fine hairs in wax sebaceous glands in the skin of the Pinna and the meatus.
The tympanic membrane is composed of connective tissues covered with skin outside and with mucus membrane inside.
The middle ear contains three ossicles called malleus,incus and stapes which are attached to the one another in a chain – like fashion.The malleus is attached to the tympanic membrane and the stapes is the attached to the oval window of the cochlea.
The ear ossicles increases the efficiency of transmission of sound waves to the inner ear.
