    besides the other, more realistic, explanations in this lovely thread, I have one more to add:

    for those of you who believe in Chi and/or chi meridians and pressure point striking, there are rather powerful points below, and above the chin, which could probably be hit with a punch.

    There is NO cheese running through your chin.... the are logical, scientific spots that do scientifically provable things.... nothing mystical about it.... I was joking in my first answer.

    Okay. Let's see if being a doctors son gave me any of the knowledge. Like some other people said before, it can cause some damage to the brain stem. Also, if you keep your mouth close, I believe that when you get hit in the chin, this will prevent the teeth from suddenly hitting each other and causing some to break or become cracked.

    Of course, I might be wrong.

    There are two ways in which hitting the chin can cause a KO.

    The first is when the chin is hit sideways, causing the head to violently turn, producing the "whiplash" effect off your brain moving violently around within your skull. In this case, keeping your mouth tightly shut tenses your neck and jaw muscles, giving your head a more stable base and causing it to move less.

    The second is when the chin is hit straight on, driving the "hinge" of your jaw back into your temporal mandibular nerve. This causes a sudden spike in blood pressure and a "brain overload" effect. This is the cause of many knockouts where it doesn't look like the person has been hit hard, but they're suddenly out. In this case, keeping your mouth tightly shut, especially around a mouthpiece, makes it harder for your jaw to move backwards and create pressure on the nerve.

    This was my understanding as well.

    FYI: The medical community actually knows very little what exactly causes a knockout.

    (This makes sense when you think about it. The medical community doesn't exactly know what causes consciousness, either.)

    The majority consensus is a knockout is caused minor trauma to the brain stem.

    So, looking at this a bit more pragmatically, accelerating the chin sideways or upwards moves the head via its strongest leverage point against the muscles which are weakest in controlling head movement, thus imparting G forces on the brain in a fashion in which it is least prepared to cope with.


    Quick acceleration + quick deceleration + multi plane directional forces = High Gs + whiplash effect = Knockout.

    Interestingly, an elite boxer's punch imparts about 52 Gs of force against the skull, yet a football player can be hit with over 200 Gs of force on the helmet with a lessor chance of being knocked out.

    Why aren't more football players knocked out? While a helmet can be a factor, the major difference is (Omega will love this) "bloxing with the face". The impact football players receive - and give to the themselves too - is almost always taken in the same plane as the rest of their body. There is no "yes/no" head motion to cause the whiplash effect.
    Calm down, it's only ones and zeros.

    I'm a first year med student, and coincidentally we just spent the last two days dissecting the temporal mandibular joints in our cadavers.

    I asked my anatomy professor what actually causes a KO from a hit to the chin - he said it wasn't so much the nerves or anything with the mandible as much as the whiplash.
