Some science behind the scenes
Nose [sides and tip]
Both the sides of the nose and the tip of the nose are trigger points. This is best seen by looking at the course of the nerves which the energy flows parallel. In the diagram below you can see that there is a cluster of nerves ending on the tip of the nose and a bunch of nerves just slightly to the side of the nose. By pressing the tip of the nose or pinching it, one is, in effect, triggering the nerves in this area.
Energy from the tip of the nose goes up to meet the energy from the front part of the skull. They all meet at the point roughly between the eyes above the bridge of the nose – the Forehead. From there it enters the skull.
Energy from the side of the nose, however, follows the course of the trigeminal nerve which you can see in the diagram to the left.
Palm pressure or finger pressure on the nostrils can temporarily slow the pulse because of a reaction in the trigeminal nerve.
The maxillary nerve (V2) carries sensory information from the lower eyelid and cheek, the nares and upper lip, the upper teeth and gums, the nasal mucosa, the palate and roof of the pharynx, the maxillary, ethmoid and sphenoid sinuses, and parts of the meninges.
