Interesting question

One of my Chicago guys, Tony Velada, sent me a link written by a kung-fu stylist about the "centerline". As all you martial artists know, we are always talking about it - what it is and where, how to protect it, how it moves, and how to control it. The article was accurate and had good detail from the internal arts point of view. I forwarded it to many of my students and former students. One of the people I sent it to is Craig Jacobus and chiropractor now living in Nebraska and teaching emergency medicine. Craig was a paramedic when I met him way back in the 70's or early 80's and went off to med school. I'd like to share his comments on the centerline as related to Western medicine, with a slant toward emergency medicine.

The concept of Centerline, as it is described can be related to what we call in trauma the "box of death". It is the mediastinal area, as you know. The middle of the chest that contains the vital organs- heart, lungs, aorta, sup/inf vena cava and of course the vagus nerve. Cranial nerve 10/ vagus nerve, "operates" the workings of a good part of the 'automatic'/ autonomic nervous system. Striking a target that is innervated by the vagus nerve (many) can cause anything from a very slow almost imperceptible heart rate to unconsciousness to multiple organic failures.
From the medical perspective, most all of the article makes sense. Coupling that with my meager early training in acupuncture, admittedly just enough so I was not ignorant but not enough to practice it, the points correlate. But the healing arts of thousands of years are still being understood and hard to correlate with our current system of only a 150 years or so.
Take care guys,
Craig Jacobus
