Question

Why do you lose consciousness when you get hit?

Answer 1

The knockout occurs because the impact of the brain hitting the cranium and the twisting of the brain stem when being hit in the jaw.



Here are a couple of webpages with some extra details:

"A knockout, or loss of consciousness, occurs for one of three reasons:

- The brain is injured as it bangs against the opposite side of the skull.

- There is a disruption in the nerve message systems of the brain...

- There is a disruption in blood flow to the brain.... If a fighter is hit “on the button,” or square on the jaw, the force of the blow is transmitted directly to the Temporomandibular joint (TMJ) where it temporarily disrupts cerebral circulation."
