At the base of the crest a minute spur of cartilage ex-tends downward, constituting the spina helicis. 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. These crura inclose be-tween them the fossa of th
