Knockout to the jaw??

Question

why those fighter who get punch to the jaw instantly goes down to the ground? how it related to the body's balance?

Answer 1

Because the "amount" of force applied to the jaw's kenetic nerves sends shockwave signals to the brains neurology system therefore disrupting neurology muscles, thus, hendering balance and alertness.

Answer 2

A couple of different factors here to be considered. First is the knock out effect itself; it can be caused a number of different ways. 1st is what they call the button, the hit that lands squarely on the tip of the chin; it triggers a knock out effect by compressing a nerve at the back of the jaw by the ear and it's lights out. 2nd is the head snap knock out effect which is where the heads snaps around with enough speed and force to cause a knock out effect. In this case the trigger is a nerve cluster in the neck that reacts to the head being turned too far too fast and shuts you down. Lastly and by far the widest ranging type of knock out comes from concussive force, and these types of knock out can occur in a variety of ways; a good hard slam, a hard shot to the side of the head, a series of shots to the head, a bug shot to the top of the head, etc, etc. The thing that these all have in common that seperates them from the other type of knock outs is that these are due to traumatic concussive force to the head as oposed to a clean shot that triggers one of the nerve clusters that causes a knock out effect. We've seen multiple examples in MMA of people actually knocking themselves out this way; off the top of my head I can remember Mark Kerr doing this in Pride, Gray Maynard in the UFC and Matt Lindland with a suplex I don't remember what show  that was not, but it's happened quite a few times. From what I have read on the subject they think it is an automatic response of the body to protect itself, especially the instant trigger knock out effects of hitting the chin squar and the head snap knock out. If you have ever turned your head so far so fast that it caused stiffness and cramping in your neck, they are related, it is in effect the same thing but on a lesser scale. As far as the relation to the body's balance; the first 2 I spoke of triggers an automatic knock out even if it is just a flash knock out of a second or two. The other can be closely related to the balance, if you get hit in the ear in sends waves of force into the inner ear which controls your equilibrium and can set you to doing the chicken dance like Sylvia was doing saturday night.

Answer 3

Actually there are 2 things -

1) The Button - this is the nerve that shuts down the brain when someone is struck in the jaw - it's located where the mandible meets the cranium - when the mandible(jawbone) is torqued correctly (across the jaw, or straight to the chin) this nerve shuts down higher brain function - some people black out completely, some freeze and fall, some lose balance and get weak-kneed.  That's why people get KO'd more when their mouths are open - the mandible is more flexed, and not held in place, so it is more likely to compress that nerve center when hit correctly.

2) concussive KO - when someone is struck across the jaw (like a right cross or roundhouse kick) or upwards (uppercut) they can be KO'd by concussion.  If the jaw is tight a strike can cause the head to rotate fast enough that the brain actually makes contact with the cranium.  The brain is "floating" in a liquid sack to protect it from this, so it takes a sharp, hard hit, or combo that causes the head to turn rapidly from one side to the other (left hook followed by right hook).   When the brain makes contact with the skull, again the higher functions shut down - balance, coordination, vision, etc.  

That's why you see fighters throwing hard twisting punches like hooks when their opponent is "turtled up" in a defensive posture, and it's why so many great fighters had the devastating left hook - it's hard to see.  Any unexpected shot can catch you turning into it or with your jaw relaxed...either way it's a KO shot.

Answer 4

A set of nerves are within the jaw muscles this explains alot

Answer 5

There is a nerve where the jaw connects to the cranium. When the jaw is impacted it sends nerfve signals to the brain. Sometimes these signals are so intense it cause the brain to shut down temporarily thus causing a knockout. Some peoples jaws are more sensative than others hence the term "Glass Jaw"
