INTRODUCTION WHAT ARE NERVE CENTERS & PRESSURE POINTS?
"Nerve centers" and "pressure points" are not scientific descriptions of anatomical entities. They are layman's terms which we use for everyday discussion of this aspect of our subject.
Nerve center is used to describe body areas which are most susceptible to pain sensation on most people because of a concentration of relatively exposed nerves.
Not all nerves are carriers of impulses experienced as pain, so not all concentrations of nerves produce a nerve center in our terms. The buttocks have a high concentration of nerves, but this area is ordinarily one of the least sensitive.
