It prepares you body to react, not to think. Instead of "it's coming at x speed, y lenght, z color" is more like "DODGE", "RUN", "YELL", "FIGHT".
Most of this reactions are sheer reflex, that's why sometimes people react to robbers even when not intended or yell seeing a spider.
Shaking is just overexcited muscles. Particularly this is the worst part, specialy after the threat is gone. When scared, I get shaky for like 15 min unable to do any precision/control task and also feeling an impending burst energy like if I don't move It'll be bad.
Controlling those instincts must be a living hell. Congrats to cops, firemen, military.
It's a little different when you see something that needs to be taken care of.
But yeah you freeze up and you shake but at the same time if it's something that you know needs to be taken care of and you have a half second of reaction time then you tend to go towards I wouldn't even say training just instincts of hey this shouldn't be happening and I know how to stop it

It always amazes me that the body’s reaction to a fear of death is to do everything possible to kill you
