What is the name of the shallowest depression of the ear?

The shallowest depression of the ear is known as the scapha. Located between the helix and the antihelix, the scapha is a narrow groove that plays a role in the overall contour of the outer ear, or auricle. Understanding the anatomical structure of the ear is essential for fields such as audiology and otology, as it provides insights into how sound is funneled and processed.

The concha, for instance, is a deeper indentation located just outside the ear canal, which is not as shallow as the scapha. The tragus is a small, pointed projection of tissue that covers the external auditory meatus, while the antihelix is a prominent ridge that forms the back part of the external ear, both serving more pronounced anatomical purposes compared to the scapha.
