Anatomy of Ear | Structure and Basic functions 

The human ear consists of three parts-the outer ear, middle ear and inner ear.The ear canal of the outer ear is separated from the air-filled tympanic cavity of the middle ear by the eardrum. The middle ear contains the three small bones-the ossicles-involved in the transmission of sound, and is connected to the throat at the nasopharynx, via the pharyngeal opening of the Eustachian tube. The inner ear contains the otolith organs-the utricle and saccule-and the semicircular canals belonging to the vestibular system, as well as the cochlea of the auditory system.
