Answer:
Goosebumps are the result of tiny muscles flexing in the skin, making hair follicles rise up a bit. This causes hairs to stand up. Goosebumps are an involuntary reaction: nerves from the sympathetic nervous system — the nerves that control the fight or flight response — control these skin muscles.
