The autonomic nervous system activates tiny muscles in the skin which causes the hairs to stand on end instead of lying flat on the skin as they usually do.
In other mammals this fluffs out the fur, increasing its ability to insulate against the cold (helping to keep warm) and making the animal look bigger (sometimes scaring away the other animal causing the original fear). But in humans all it does is cause bumps in the skin around the bases of the hairs, these bumps are commonly called "goose bumps".
