Antitragus Transverse Sulcus: Anatomical Description and Role in Human Health

The transverse antitragus groove (sulcus anthelicis transversus) is a small groove located on the outer surface of the auricle, not far from the tragus. It can be designated by several synonyms such as PNA, BNA or JNA. Despite its small size, the transverse antitragus groove is important for the anatomy of the ear and can affect human health.

Anatomically, the transverse antitragal groove is located on the upper part of the auricle, where the skin meets the cartilage tissue. This groove has the shape of a semicircular canal, which is located across the auricle and can be seen with the naked eye. The antitragus groove transversalis is one of many grooves on the pinna that help capture sound waves and direct them into the ear canal.

The importance of the transverse antitragus groove lies in its role in creating the sound channel. This groove and other grooves on the pinna help direct sound waves into the ear canal, where they can be picked up by the ear and transmitted to the inner ear for processing. Due to this function, the transverse antitragus groove plays an important role in the process of hearing, which is one of the basic human senses.

In addition, the transverse antitragus groove can also help prevent certain health problems. For example, some people may have a deeper or less pronounced antitragus groove, which can lead to problems with sound waves penetrating the ear canal. This can lead to poor hearing or other hearing-related health problems. Therefore, it is important to pay attention to the condition of the transverse antitragus groove and other grooves on the auricle as a whole.

In conclusion, the transverse antitragus groove is a small but important anatomical feature of the auricle that plays an important role in the hearing process and can help prevent several health problems. Therefore, it is important to understand its importance and monitor its condition to maintain healthy ears and hearing.
