    acanthion (acan) alveolon (alv) The point of the nasal spine, upon the lower border of the piriform aperture. This point, formerly much used, has now been mainly superseded by the nasospinale, q.v. A point on the bony palate where a line drawn through the termini of the alveolar ridges crosses the median line. In practice this point is readily determined by placing a fine knitting needle across the palate, just back of the posterior ends of the alveolar ridge, and marking the point where this crosses the median suture of the palate bones.

For the meaning of the asterion (ast) f auriculare (au) f A point behind the base of the mastoid process, where the lambdoidal, parieto-squamous, and oc- cipito-squamous sutures come together, defining the boundaries of parietal, occipital, and temporal bones. A point vertically above the center of the auditory meatus, and crossing the root or base of the zygoma. This point is but a few millimeters above the porion.
