The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [1] It gathers sound energy and focuses it on the eardrum (tympanic membrane).
The outer ear, also known as the external ear or auris externa, consists of the auricle, ear canal, and eardrum. They work together to funnel sound waves from the environment to the middle and inner ear, where they are translated into nerve impulses for the brain.
The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule.
Also called the auricle or pinna, your outer ear consists of ridged cartilage and skin, and it contains glands that secrete earwax. Its funnel-shaped canal leads to your eardrum, or tympanic membrane.

This article will focus on the anatomy of the external ear – its structure, neurovascular supply and clinical correlations. The external ear can be divided functionally and structurally into two parts; the auricle (or pinna), and the external acoustic meatus – which ends at the tympanic membrane.
The outer Ear is the part you can see, including the flap of skin called the pinna and the tube-like ear canal. The middle Ear is inside your head, and there is a space called the middle Ear. It has three tiny bones called ossicles and a cavity called the tympanic cavity. The inner Ear is part deep inside your head and is filled with fluid.
Introduction. The external ear is the visible part of the hearing apparatus. It is comprised of the auricle (pinna) and external auditory canal, including the lateral surface of the tympanic membrane. Together with the tympanic membrane and the middle ear, the pinna serves to amplify sound.
The Outer Ear. The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified. The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
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 function of the outer ear is to collect sound waves and guide them to the tympanic membrane.
