Scalp acupuncture line (WHO 1991) · Scalp — Forehead
Location
On the forehead, a 1 cun line running from BL3 straight down along the Bladder channel.
Distances are in cun, a proportional unit — how to measure.
Clinical Notes
One of the fourteen scalp acupuncture lines of the WHO 1991 standard nomenclature. The lines were formerly named after the functional zones of the brain beneath them; the standard renamed them by surface anatomy so they are easier to locate, without changing that relationship.
