eli5- How does getting hit in the chin cause you to go unconscious?

Title says it. I have never questioned the idea of a “glass jaw” and have experienced it first hand. While it makes sense for a head injury to have side effects, what is it about the jaw that leads to K.O.’s?

Theres a few different mechanisms behind it. A strike to the head leaves the brain bouncing around inside and enough of that will cause a reaction similar to an emergency reboot on a computer.

Also along your neck there are bundles of nerves that travel behind the jaw. A quick pinch of the nervebundle will overload the brain and again. Restart

You can be knocked out by any violent abrupt strike to the head. Also your diaphragm, chest, and gut can ge hot hard enough to knock you out also
