Little muscles at the base of each hair shaft called arrector pili (also Erector pili).

When we are cold, muscles just below our skin, called erector muscles, contract. This pulls on our hairs, causing them to stand on end. By doing this, the hairs form an insulating layer of air, which keeps us warm and maintans our constant internal body temperature.

When an animal feels cold it puffs up its fur in order to create air pockets which act as insulation. Humans have hair that is too short to be effective in this manner but the nervous system still responds in the same manner to the sensation of coldness.

A smooth muscle, the arrector pili, attaches to the follicle in such a way that contraction of the muscle causes the hair to stand on end. If a person

has had a scare or is cold, "goose bumps" develop due to contraction

of these muscles.
