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
Makes the hair follicle stand upright
The erector pili muscle is a small muscle attached to hair follicles in mammalian skin. Its contraction causes hairs to stand on end, creating "goosebumps" or piloerection. This response is part of the body's fight or flight reaction to cold, fear, or other stimuli.
It causes erection of hair when stimulated by the sympathetic nervous system.
