POSTTRAGUS Meaning and
Definition
-
Posttragus is a term used in anatomy to describe a small, fleshy projection of tissue located posteriorly to the tragus, in the outer ear, in humans and certain animals. It is situated just above the external auditory meatus (ear canal), extending back towards the posterior part of the auricle. The posttragus is often considered as a part of the auricle or pinna, which is the visible external portion of the ear.
The posttragus, although relatively small in size, plays an important role in the overall structure and function of the ear. Along with the tragus and other anatomical components, it helps to direct sounds into the ear canal, assisting in the process of sound perception and localization. It contributes to the intricate mechanism of the outer ear, aiding in the collection and conduction of sound waves towards the middle and inner ear.
Beyond its anatomical significance, the posttragus has also been studied in relation to certain medical conditions. For example, it has been observed that in individuals with a congenital anomaly known as Treacher Collins syndrome, the posttragus may be absent or underdeveloped. Understanding the variations and features of the posttragus contributes to our knowledge of ear anatomy and can have implications for surgical procedures or diagnostic examinations involving the outer ear.
