The outer ear consists of the visible portion called the auricle, or pinna, which projects from the side of the head, and the short external auditory canal, the inner end of which is closed by the tympanic membrane, commonly called the eardrum. The anatomy of the external ear, also known as the auricle or pinna, is complex [Hunter and Yotsuyanagi, ] and remarkably inaccurately described by most authors. The inner ear is also called as labyrinth because of its intricate structure of interconnecting chamber and passage. They send the sound waves to the inner ear and into the fluid-filled hearing organ (cochlea). The eustachian tube is lined with mucous, just like the inside of the nose and throat. The human ear is one of the more remarkable parts of the human body, not only because of the beauty and unlikelihood of its structure, but also because of its remarkable sensitivity to sounds.

The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The inner ear consists of two functional units: the vestibular apparatus, consisting of the vestibule and semicircular canals, which contains the sensory organs of postural equilibrium; and the snail-shell-like cochlea, which contains the sensory organ of hearing. External auditory canal or tube. The ear can be divided into three parts; external, middle and inner.This article will focus on the anatomy of the external ear – its structure, neurovascular supply and clinical correlations.

From this duct a long tube, the ductus endolymphaticus arises which ends blindly as the saccus human ear, organ of hearing and equilibrium that detects and analyzes noises by transduction (or the conversion of sound waves into electrochemical impulses) and maintains the sense of balance (equilibrium). Eustachian tube. The outer ear is the external portion of the ear and includes the fleshy visible pinna (also called the auricle), the ear canal, and the outer layer of the eardrum (also called the tympanic membrane). The middle ear is an air-filled cavity that turns sound waves into vibrations and delivers them to the inner ear. Watch video on the structure of the ear and understand how human ear looks and work. It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles. Eustachian Tube – This tube equalises air pressure.
