arrector pilli
What is the function of the hair erector muscle?
i assumed you are referring to the arrector pili muscle. usually when you are cold or scared, this muscle contracts, pulling the hair follicle in a upright position. the dents created are called goosebumps. it provides insulation and protects the hair
