For our friend Hedgehogey's sake (primarily so he will not get his gi pants in a wad and cut off blood flow), I will choose a location that has both a Modern Western Medical (MWM) and Traditional Chinese Medicine (TCM or Zhongyixue in Chinese) approach. <grin!>
Look to the Axilla, Axillary Fossa or Axillary Cavity...also known as the armpit. From the TCM paradign, we would be speaking of the HT-1 (Heart 1) point called Jiquan (Summit Spring).
At this location, we are dealing with the upper roots of the brachial plexus. In this area, the brachial plexus exits the neck, goes over the first rib and under the clavicle. It then traverses under the corcoid process and inserts into pectoralis minor and then onto the axilla and then on down the arm (for those of you that do not know or don't have a copy of Gray's Anatomy handy, the brachial plexus (and here we are talking of including the C-8 and T-1 nerve roots) is a part of the Sympathetic Nervous System and is a network of motor and sensory nerves which innervate the hand, the arm, the shoulder and upper chest girdle. Local anatomy includes the subclavian artery and vein, the axillary artery, etc.
In this particular case, the trapezius and levator scapulae muscles protect from unwanted compression of the brachial plexus by the clavicle as it goes over the first rib. This is important. When watching sports, you have heard of them refer to a "stinger", right? That is what this unwanted compression is. when you see a hockey player get checked into the boards or a football running back hit the line with a lowered shoulder and head (or up ended and landing on the shoulder), this creates the unwanted compression and hence the stinger. This also brings up the use of terms...is this a point that lays someone out stiff as a board and unable to move? No. Are they paralyzed? To me yes...look at the guy with the stinger in the example above. For all practical purposes, he is paralyzed. He can do nothing. It is like saying that "if it don't work, it is broken". In the strictest technical sense does it really matter if an elbow is dislocated or the arm is broken? Are the short term immediate results pretty much the same?
To attack this point, use something like Nakadakaken (Nakadaka Ipponken), Keikoken, Nihon Nukite, Ippon Nukite, Boshiken or even Koken. I am not a fan of Koken as it provides for a much larger striking surface or area of target impact, but when delivered with Te no Omoi, proper Kiryoku and the resulting Chiru Nu Chan Chan...then it will surely have the desired result.
That help any at all with the original question?
