crossing point: meeting of governor vessel (GV) and foot taiyang.

[Origin]

The point is near the large foramen of the occipital bone, which is the portal of the brain. The point is above Fengfu (GV16), so it is also called "Za Feng". Some occipital bones are mutated, and there are bone sutures here, so they are also called "joint skulls".

[Location]

Naohu (GV17) acupoint
(quoted from "Meridians and Acupoints")

• Zhenjiu Jiayi Jing: "On occipital bone, Qiangjian (GV18) is one and a half inches behind";
• Yizong jinjian: "One inch and five minutes upward from Fengfu (GV16)": that is, the upper edge of the external occipital protuberance.
• Leijing Tuyi: "One day is two inches above hairline";
• Zhenjiu Jicheng: "On occipital bone", then the acupoint is located in the depression at the lower edge of the external occipital protuberance. If acupuncture is performed here, especially when the patient is prone, do not puncture deeply, lest the needle penetrates deep along the nuchal septum, penetrates the posterior circumoccipital membrane, and stabs the medulla oblongata, causing danger.

[Anatomy]

• Muscles: between the left and right occipital muscles.
• Nerve: branches of the greater occipital nerve.
• Blood vessels: branches of the left and right occipital arteries and veins, and often conductive vessels in the deep layers.

[Manipulation]

Subcutaneous insertion 0.3~0.5 inches. Direct moxibustion is prohibited. In some people, the occipital bone may be mutated. The upper part of the occipital bone (membrane source bone) is separated from the other parts of the occipital bone (the original cartilage bone) and becomes an independent interparietal bone, resulting in a transverse occipital suture slightly above the uppermost nuchal line. When Naohu (GV17) is acupunctured within one or two years after birth, because the bone edges on both sides of the suture are not tightly connected to each other, the needle may penetrate into the skull through the transverse occipital suture and injure the superior sagittal sinus (the vein of the hard brain membrane). The posterior end of the sinus and the occipital poles of the brain on both sides. However, when the occipital bone is normal or the interparietal bones are incompletely separated despite variations, that is, the transverse occipital suture appears only on both sides, there is no such possibility, and moxibustion is generally not performed.
