Which area of the ear corresponds to the shoulder, elbow, wrist, and fingers?

The area of the ear that corresponds to the shoulder, elbow, wrist, and fingers is the scapha. In auricular acupuncture, different parts of the ear are thought to represent different parts of the body based on specific mappings.

The scapha is the elongated, shallow depression located between the antihelix and the helix of the ear. According to traditional ear acupuncture maps, this specific area correlates with the upper extremities, including the shoulder, elbow, wrist, and fingers. The anatomical structure and location of the scapha allow it to represent these areas effectively within the ear-to-body correspondence utilized in acupuncture.

Other areas of the ear, such as the antitragus, cymba conchae, and cavum conchae, correspond to different bodily systems or parts and do not represent the shoulder to finger areas. Understanding these anatomical mappings is essential for practitioners to effectively utilize auricular acupuncture for therapeutic purposes.
