What would happen if you get punch/uppercut somebody in center of chin?

wen u lose control of your leg, its called a knockout. your chin is not conected to your brain. wen u get hit in the chin your brain hits your scull with alot of power, because your head moves in a fast motion, wen your brain hits the side of your scull hard enough you get you nerves send signals to your leg and your legs gives in, then u get knockedout. so it really does not matter if u get hit in the chin, or in the nose, its all about how the striker hits u.
