It’s uniquely shaped with features such as the tragus and antitragus. But there’s more to it than just structure – our ears can encounter problems too, like cancer or inflammation that could mess up their job.

May 17, 2024 · The outer ear, also known as the external ear or auris externa, is the part of the ear exposed to the environment that serves as the vehicle to receive sound waves from the air. The size and shape of the outer ear are different for …

Amplification of sound by the pinna, tympanic membrane and middle ear causes an increase in level of about 10 to 15 dB in a frequency range of 1.5 kHz to 7 kHz. This amplification is an important factor in inner ear trauma resulting from elevated sound levels.

In human ear: Outer ear …acoustic meatus, is called the concha. It is partly covered by two small projections, the tonguelike tragus in front and the antitragus behind. Above the tragus a prominent ridge, the helix, arises from the floor of the concha and continues as the incurved rim of the upper portion of the… Read More; physiology of ...

The concha is the "shell-shaped" structure of the cavity of the external ear. The antitragus is the inferior margin of cartilage opposite the tragus. The tragus is the small epidermal fold just in front of the ear canal. The aperture opens into the ear canal. The adult ear canal is approximately 1.5 inches in length.

Aug 16, 2020 · 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.

Nov 3, 2023 · The center of the auricle has a fossa that is continuous with the external acoustic meatus called the concha of the auricle. This concha is covered with a triangular cartilaginous process called the tragus. The base of the tragus is attached to facial skin, whereas its apex partially covers the entrance to the external acoustic meatus.
