          Why do we gasp, jump and go pale when we're frightened? It all comes down to a tiny, almond-shaped structure in the brain that's called the amygdala.																									Matthew Orr, Alex Hogan/STAT
          It feels like your body reacts a million different ways when you get scared — the blood rushes out of your face, you jump, you gasp, your heart starts racing.
          But what’s happening inside your body that makes you feel afraid?

          It all comes down to a tiny, almond-shaped structure in the brain that’s called the amygdala.
          It’s responsible for kickstarting your “startle response.” That sends out a distress signal to the hypothalamus, and from there, your brain makes the call between fight and flight.
