			Cranial surface of cartilage of right auricula.

			The cartilage of the auricula (cartilago auriculæ; cartilage of the pinna) ([[:File:Gray0905.jpg\|Fig. 905]], [[:File:Gray0906.jpg\|Fig. 906]]) consists of a single piece; it gives form to this part of the ear, and upon its surface are found the eminences and depressions above described. It is absent from the lobule; it is deficient, also, between the tragus and beginning of the helix, the gap being filled up by dense fibrous tissue. At the front part of the auricula, where the helix bends upward, is a small projection of cartilage, called the spina helicis, while in the lower part of the helix the cartilage is prolonged downward as a tail-like process, the cauda helicis; this is separated from the antihelix by a fissure, the fissura antitragohelicina.
