* The "Helicis major" is a narrow vertical band situated upon the anterior margin of the helix. It arises below, from the spina helicis, and is inserted into the anterior border of the helix, just where it is about to curve backward.
* The "Helicis minor" is an oblique fasciculus, covering the crus helicis.
* The "Tragicus" is a short, flattened vertical band on the lateral surface of the tragus.
* The "Antitragicus" arises from the outer part of the antitragus, and is inserted into the cauda helicis and antihelix.
* The "Transversus auriculæ" is placed on the cranial surface of the pinna. It consists of scattered fibers, partly tendinous and partly muscular, extending from the eminentia conchae to the prominence corresponding with the scapha.
* The "Obliquus auriculæ", also on the cranial surface, consists of a few fibers extending from the upper and back part of the concha to the convexity immediately above it.
