Which of these fields do you fold in under pressure points?

Pressure points run along and sometimes coincide with the anatomical parts you listed, but they themselves are not THE pressure points.

And how the UKE is affected depends on how you attack the PP. There are different approaches for attacking them depending on how extreme you want the effect or whether or not you want to control the attacker or just create an imbalance that leaves him disoriented.

A Kyushojutsu principle is Compounding. Just like words, they take meaning when you compound them according to 5 Element Theory.

If you don't understand and use the science, you can not affect the opponent.

You have two choices,cause pain,or shut off blood flow. Both will fold someone,but depends on the application. So all those listed.

People have told me that they all count as pressure points but if what darth says is true and none of them are then I don't believe pressure points to be a useful combat application. They're simply too hard to hit in the motion of a fight, even in a clinch people squirm.
