The first receptor
The skin contains receptors as all know, but with many facets that help the Kyusho practitioner.
For eons the term "Death Touch" has been used and mis-used in the Kyusho and or Dim Mak study. It does not mean that someone can merely touch another and kill them...that's movie stuff folks. However touch or other methods of light contact does "HELP" with Kyusho.
Let's start with the first encountered anatomical structure extending from the skin, that is hair. Hair is in part has a sensory function, whereas the slightest moment transmits sensory input to the nervous system.
Once the skin is reached there are the Sudoriparous Gland (sweat glands) sweat gland innervation occurs more generally in sympathetic neurons and each sweat gland receives several nerve fibers that branch out into bands and encircle the individual tubules of the secretory coil. These are subsurface whereas the hairs were above the surface. This is the second sensory monitor right after the hair has been in contact with. Both of these structures account for the immediate sense of the feeling of touch.
The third level of reception lay in the Dermis or skin and is from the network of nerve corpuscles, these are unmylenated (Myelin is a fatty substance surrounding the axon of some nerve cells, forming an electrically insulated layer). Some are highly receptive, some to touch, some to temperature, some to pressure or vibration. As example there are: the Krause Corpuscle – nerve ending is sensitive to cold, the Pacinis Corpuscle – nerve ending is vital sensitive. It reacts with free nerve endings, the Ruffinis Corpuscle – nerve endings that are heat sensitive., etc. Deeper in the dermis are the free nerve endings, these are unspecialized, afferent nerve endings, which means it brings information from the body's periphery toward the brain, used by vertebrates to detect pain.
So what we can learn and apply to Kyusho is that just light touch, opens the bodies sensory system as it is transferred to the central nervous system. The light touch is not protected against with reflexive actions and or muscle constriction. This enables the Kyusho attack to be more readily effective and have more profound affect. This is equally important for Martial application as well as health, energy development and intimacy enhancement.
And although easy to play with, to learn real combative methodology with it takes long hard practice... no shortcuts or magic "TCM" recipes. This is part of what the old masters knew and wrote about, this is also what Kata is about... soft and hard actions in harmony throughout... Kata can be used as the first stepping stone in application.
