Innervation of the Human Cavum Conchae and Auditory Canal: Anatomical Basis for Transcutaneous Auricular Nerve Stimulation

Figure 7

Schematic representation of the quantitative results in the cavum conchae (A) and external (B) and internal (C) segments of MAEC. (a) Data below the blue line corresponds to the anterior-lateral side of the cavum conchae, and those above the blue line correspond to the posterior-medial side of the cavum conchae. (b) Lateral segment of MAEC representing the data out of and inside the cartilage (blue line); (c) medial segment of MAEC representing the data out of and inside the cartilage (blue line). Numbers in red correspond to the percentage of myelinated nerve fibers.
