Anatomical terminology

The nasion (nā′zē än′) is the intersection of the frontal bone and two nasal bones of the human skull. Its manifestation on the visible surface of the face is a distinctly depressed area directly between the eyes, just superior to the bridge of the nose.[1] It is a cephalometric landmark that is just inferior to the glabella.
