Followed inthe opposite direction, thehelix is seen to terminatein an elongated cartilagi-nous process, the processuscaudatus; the spine of thehelix and the caudate pro-cess can rarely be recog-nized on the living subject,but are discernible uponthe cadaver after carefullyremoving the integumentcovering the auricle (Fig. The groove beneath thehelix is called the fossa ofthe helix, or scaphoid fossa. Immediately in front of thisfossa is a broad convex ridge running parallel to the helixcalled the antihelix, dividing above into two branches—thecrura helicis or the crura furcata.
