Vital Point
Vital Point means, for example, any point on an aircraft at which single mal-assembly could lead to catastrophe, i.e., result in loss of aircraft and fatalities [Law Insider].
In medicine, a vital point is a pressure-sensitive point on or near the surface of the human body. Vital points function like gateways to the nervous system, the central controller of the body, allowing you to use pain to influence the actions and reactions of an opponent. Even a single strike can cause severe damage, unconsciousness, or, in rare cases, death.
For example, a forceful strike into the Wind Mansion (GV16) at the base of the brain can result in instant death. The gallbladder (on the right side of the trunk, below the liver) and the Sauce Receptacle (CV24) on the tip of the chin are targets for potential knockout blows in boxing. The carotid artery, temple, and Philtrum are common targets for striking in a self-defense situation [Kim, p. 112].
