the pointed chin= knockout?

[Zero_Sen]

1. Chuck Liddell has a pointy chin and can take a beating.

2. The whole "button" (or as rogan put it once, a nerve at the back of the jaw that Kos you when compressed) is a bit of a myth; most physiologists contend that knock outs occur from a sharp/fast rotation of the head or from a blow causing sufficient force to concuss.

I think it has more to do with jaw displacement leading to a more violent bouncing around of the brain in the skull.

Hit anywhere on the lower jaw and you will hurt your opponent....the lower on the jaw you hit (i.e: the chin) the more displacement you cause.

The worst chin knockouts are the perfectly straight power shots that hit perfectly in that divot between the bottom of the lip and the "top" of the chin, and compress the lower jaw way back; they are rare but they do happen. Like Rogan has mentioned a few times, there's a nerve(s) somewhere in there and when it receives enough trauma is when you drop. I'm pretty sure any animal that's got a nervous system that is reminiscent in that area to our own has it - if you fish and you ever hook a fish down through its tongue about midway back or further it literally paralyzes it and it eventually just dies; perhaps not the same thing, but a testament to the significance of the nerves and whatnot located back/below the tongue.

It seems that in most cases, a thick neck adds resistance against the KO. Other things that I suspect (usually) help is more prominent bone structure and less prominent nerves... basically; no body part(s) is exactly the same size / level of sensitivity from person to person.

Given the complexity of the body and how so many things are interrelated there are probably countless little contributors to ones KO resistance or lack thereof but I think basically what it comes down to is anatomy + how / where you get it.

What about Inoki's chin?

thats my point, and it would make sense the pointier the chin the more rotation, right?

The brain is surrounded by cerebrospinal fluid, one of the functions of which is to protect it from light trauma, but more severe impacts or the forces associated with rapid acceleration and deceleration may not be absorbed by this cushion. Concussion may be caused by impact forces, in which the head strikes or is struck by something, or impulsive forces, in which the head moves without itself being subject to blunt trauma (for example, when the chest hits something and the head snaps forward).

Forces may cause linear, rotational, or angular movement of the brain, or a combination of these types of motion. In rotational movement, the head turns around its center of gravity, and in angular movement it turns on an axis other than its center of gravity. The amount of rotational force is thought to be the major type of force to cause concussion and the largest component in its severity. Studies with athletes have shown that the amount of force and the location of the impact are not necessarily correlated to the severity of the concussion or its symptoms, and have called into question the threshold for concussion previously thought to exist at around 70-75g.

The parts of the brain most affected by rotational forces are the midbrain and diencephalon. It is thought that the forces from the injury disrupt the normal cellular activities in the reticular activating system located in these areas, and that this disruption produces the loss of consciousness often seen in concussion. Other areas of the brain that may be affected include the upper part of the brain stem, the fornix, the corpus callosum, the temporal lobe, and the frontal lobe.


According to the classic definition, no structural brain damage occurs in concussion; it is a functional state, meaning that symptoms are caused primarily by temporary biochemical changes in neurons, taking place for example at their cell membranes and synapses.

He sure can...well, unless Rampage is handing it out.

is do to the fact that when you hit the chin, the chin is the point of the head so it casues the head to make more of a rotation, shaking your brain and skull to its capacity.

a good analogy would be kicking a football. if one kicks the point it will spin faster then if you kick the middle.

If my logic is understandable it brings me to my next point. wouldn't this mean that the more pointed your jaw bone and chin are then on average u will be more easily knockedout. and that if u have a non-pointed chin(dont know what else to call it) then on average you will be harder to knockout?

1. anyone see any major flaws with my above statement?
2. can anyone give examples of people with pointed jaws that have glass jaws or the opposite

Disclaimer: i said on AVERAGE, there will always be many exceptions to any rule
and please, try not to bash me too much

the reason people get knocked out is when your jaw hits a nerve in your head that makes you go unconcious for a bit

dan henderson got pointed chin does he? how about A silva? he dont have a big chin like fuji, he can take a hit

the reason you get knocked is out is because your brain rattles against your skull.
