BELLEVUE MAN HAIR FACT: Goose Bumps

Goose bumps are created when tiny muscles at the base of each hair, known as ARRECTOR PILI MUSCLE, contract and pull the hair erect. The reflex is started by the sympathetic nervous system, which is responsible for many fight-or-flight responses.

I always make a joke when I get goosebumps and say " My arrector pili muscles are contracting!"
