KNOCKOUT BLOWS

KNOCKOUT BLOWS.

There Are Many Vulnerable Points In Man's Anatomy.

An impression prevails that there is only one blow - that on the point of the jaw - which really constitutes the knockout blow, says a writer in the Britsh Medical Journal. This is an error. The temple is a very vulnerable part of the head, the iesion usually produced being laceration of the brain substance, with hemorrhage. A blow on the ear may cause a rupture in the membrana tympani and collapse. Dangerous points are over the carotid and on the larynx, the danger lying in the concussion conveyed through the large nerve trunks which run down the neck. A blow on the larynx with the bare fist may cause instant death, as may one on the chest well over the heart. Diaphragmatic blows are not so dangerous to life, the shock being temporary. Brisk rubbing and the use of stimulants is the most satisfactory mode of treatment. Blows over the kidneys may cause rupture and hemorrhage, with intense pain and shock. The most dangerous and infinitely painful for of knockout blow is that on the "mark," an area of the abdominal wall corresponding to the center of a triangle formed by the xiphosternal articulation above and a line joining the bony ends of the seventh ribs below. Behind this lies the pyloric end of the stomach. A blow here constitutes the "solar plexus" blow, but in reality it is the stomach which receives and transmits the shock.
