The American way to spell the word is erector pili. This refers to the muscle connected to the hairs on the arms and other areas. Any erector muscle refers to a muscle that raises a body part in the event there is a signal to the brain that the body is no longer in the state of homeostasis. Meaning if the body temperature falls below or rises above normal, the erector pili muscle is targeted to cause the hairs to stand up and the body to get cold chills. This is one way the body returns to a homeostatic level.
