3 Anatomical Orientation
Forehead (Figs 3.10, 3.11)
The more or less prominent bulge of the frontal eminences can
be palpated on both sides of the forehead. G.B.-14is located
at their lower border, in a shallow depression at the junction of
the eminences and the superciliary arches. With the patient look-
ing straight ahead, G.B.-14 is located directly above the pupil,
approximately 1 cun superior to the supraorbital margin.
Glabella, superciliary arches
The glabella is the central bony reference point on the forehead,
forming a slightly convex, level area superior to the root of the
nose and between the superciliary arches.
The extra point yintang(Ex-HN-3) is located at the centre of
the glabella. Several points are located along the superciliary
arches (from medial to lateral): BL-2, yuyao(Ex-HN-4) and
T.B.-23.
Please note:BL-2is located superior to the inner canthus of
the eye, in the area of the frontal (not the supraorbital) incisure,
when this is present.
