Fig. 1. Human Adult Auricular Cartilage

The auricular cartilage is viewed from the median side, thus showing the two eminences which constitute its main area of contact with the skull.

In figure 2 can be seen the cavities (fossae articulares) of these eminences and the plica principalis projecting between them as a strengthening ridge.

Terms

  • Eminentia articularis inferior - See Eminentia articularis superior, formerly known as eminentia concha.
  • Eminentia articularis superior - Same as eminentia fossae triangularis. The pars articularis of the concha, as viewed from the median side, presents two eminences which constitute the chief area of contact of the auricle with the skull. In this paper these are designated, respectively, eminentia articularis superior and eminentia articularis inferior. (See fig. 1.) The groove between them is the sulcus corresponding to the plica principalis.
  • Plica principalis - [Boas]. Equivalent to crus inferius anthelicis. Introduced because it is more accurately applied, particularly to the auricle of mammals other than man.
  • Scapha - Concave surface of the free portion of the auricle lying between the anthelix and the helix. Term applied by Henneberg to the entire free auricle from the anthelix to the free border. He applies the term helix to the unwrinkled border of the scapha.
  • Spina helicis - Cartilaginous process extending forward from the pars articularis concha?. (See fig. 1.) It is not in reality a part of the helix. It is supposed that this structure is enlarged and becomes detached in some mammals to form the scutulum.
