What are the two legs that the antihelix splits into?

The antihelix is a prominent feature of the ear, specifically part of the auricle, and serves a crucial role in its anatomy. It is the raised ridge that can be seen as part of the external ear, and it splits into two distinct legs, known as the superior crura and the anterior crura. This anatomical division provides structural support and aids in the overall shape of the ear, contributing to its function in sound localization.

The superior crura extends upwards, while the anterior crura projects forward, effectively anchoring the antihelix and helping to create the distinctive contours of the auricle. Understanding this anatomical detail is essential in fields such as audiology and otolaryngology, as alterations or abnormalities in this structure can have implications for hearing and ear-related conditions.
