Did you know goosebumps are caused by a muscle?
At the base of every hair follicle are tiny fan-shaped muscles called Arrector pili. These muscles contract when the body is cold to warm it up and cause a person's hair to "stand up straight" on their skin, aka goosebumps.

As the tiny muscles attached to each of your hairs tighten, they shoot straight into the air, pulling the skin at their base upward.
