Tubercle of the Auricle [Tuberculum Auriculae, PNA, JNA Tuberculum Auriculae (Darwini), BNA syn. Darwin Bouguro]
The Auricular Tubercle, also known as the Tuberculum Auriculae or Darwin's Tuberculum, is a protrusion of the anterior edge of the upper part of the helix of the auricle. This anatomical feature of the human ear was named after the famous English naturalist Charles Darwin, who studied its structure and function in his research.
The pinna tubercle is a small convex formation located on the anterior edge of the upper part of the helix of the auricle. It can be found on both human ears and usually ranges in size from a few millimeters to one centimeter. Externally, the tubercle looks like a small protrusion or bump on the auricle.
Although the exact function of the Pinna Tubercle is not entirely clear, there are several suggestions about its possible role. Some researchers believe it may be related to amplification of sound waves and improved perception of high-frequency sounds. It is assumed that the Tuberculum of the Auricle may serve to focus sound waves and direct them to sound receptors, such as the external auditory canal and the pinna.
Other researchers have suggested that the Pinna may have a role in controlling and regulating the acoustic characteristics of the pinna. It can participate in the formation of resonant frequencies and improve the perception of sound information. However, further research is needed to more accurately determine its functional role and contribution to the process of auditory perception.
The pinna tubercle may also have implications in clinical practice. Otolaryngologists and audiologists may look for this anatomical feature when examining patients' ears. It can be used as a guide to determine the position and shape of the auricle, as well as to assess possible violations of its structure.
In conclusion, the Tuberculum Auriculae or Darwin's Tuberculum is a protrusion of the anterior edge of the upper part of the helix of the auricle. Although its function is not fully understood, it may play a role in improving the perception of sound waves and regulating the acoustic characteristics of the auricle. More in-depth research is needed to fully understand its role. The pinna tubercle can also be useful in clinical practice to assess the structure and condition of the pinna in patients.
