Goosebumps are fun little happenings

Have you ever watched your skin when you have goosebumps? Did you know that is a muscle contraction making your hairs raise up and thus pulling your skin into "bump like" status? The erector pillae muscles surround each hair on your body and when your nervous system excites them they contract making the hairs stand "erect". I just got goosebumps from a breeze in the air, and watched my arms as the goosebumps settled down. I saw almost in tiny waves the hair relax a little more and a little more as the muscles lost tone. It was amazing really to watch the body at work. Such a tiny thing, and yet it can tell you a lot about your body and your environment.
