Strikes and Their Reactions

Autonomic: Occurring involuntarily, automatic. Of or controlled by the autonomic nervous system.

When there is a strike to a section of the body, an autonomic reaction occurs. The body and mind react to the pain in a certain way. The way the body acts depends on how and where the body is hit.

If you know how a person will act against your attacks you can also predict his defenses. By knowing how the attackers will move, I take away his defense to my actions.

All humans are basically the same. Therefore, all autonomic reactions will be the same. If you strike a person in the left side, hitting the lower ribs the person would bend towards the left side and the hands would come in toward the ribs. While bending to the pain, he can not keep up his defense. This also leaves him open to other attacks.

 Area  Autonomic Response
Forehead, Nose
Head will go back, hands will come up to protect face
He will step back one full step with the same side foot, grab eye with closest hand, than bring other hand over first one
Temple/Right or Left Head moves in same direction as strike
Kneecap The knee must first be straight, allowing the knee cap to float. You can kick on the front or on the side of the leg. The body will collapse and the uki will grab the knee causing him to go down
Knee joint The knee must be straight. Kick or stomp the knee, driving through the knee. This puts the knee in a direction it is not suppose to go. Uki will react as with the knee cap
Ankle Foot will collapse into the strike
Base of skull Head will go forward, body will follow
Base of neck Head will go back
Kidney If you can hit the kidney right on with enough force, the person will drop to the floor
Groin The person will squat down onto his knees, his back will arch, with head back exposing the throat. They will grab the groin and roll to the ground
Bladder Striking the bladder will cause the immediate weakening of the person. The head will go down
Back of knee Knee will buckle, body will fall
Tailbone If you break or crush this bone, the person will not be able to walk or stand up without a lot of pain
Jaw Strike The jaw where it connects to the rest of the skull. In front of the lower part of the ear. If the mouth is open, only 3 to 4 pounds of pressure will break the jaw
Throat or Windpipe He will step back and turn his head towards the leg he stepped back with

Neck side 

There is a nerve that starts under the ear and runs down the side of the neck. Using the forearm strike this nerve on the left side of the neck. Uki will bend away from the strike lifting his same-side foot. He will stumble back and fall down
Throat Uki will step back a full step. He will not rotate, until he has fully stepped back. Striking the throat will cause the uki to choke, which will decrease his will to fight
Collarbone Striking down on the collarbone will cause the uki to stoop down to get away from the pain. The arm on that side will be hard to lift due to the pain
Elbow, Hand, Wrist Uki will pull area away from pain and step back
Solar Plexus A strike here will cause the uki to bend straight forward and bring his head down (step to side with the strike so you do not get hit with his head on the way down)
Stomach Body will bend forward hands. will come up to hold stomach
Thigh muscle Muscle will cramp, making it hard to stand
Bicep muscle A strike to this area keeps the arm from being able to strike out and will keep the arm from lifting. It will also straighten out the arm
Shin, instep, toes Very painful. Body will react to pain and try to get away
