Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction and maintains the sense of balance. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. Learn about the anatomy and physiology of the human ear in this article.
In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. [ 1 ]

The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells. Hearing: The eardrum vibrates when sound waves enter the ear...
Human ear - Anatomy, Hearing, Balance: The most-striking differences between the human ear and the ears of other mammals are in the structure of the outermost part, the auricle. In humans the auricle is an almost rudimentary, usually immobile shell that lies close to the side of the head.
Synonyms: External auditory meatus, External acoustic pore , show more... The ear is a complex part of an even more complex sensory system. It is situated bilaterally on the human skull, at the same level as the nose. The main functions of the ear are, of course, hearing, as well as constantly maintaining balance.
Know how human ears help to perceive and distinguish sounds The ear is the organ of hearing; it enables the perception of sound. Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds.
Vision, Hearing and Speech Aging and Hearing. Understanding the parts of the ear — and the role of each in processing sounds — can help you better understand hearing loss. The Outer Ear. The auricle (pinna) is the visible portion of the outer ear.
