The arrector pili muscle is a small smooth muscle attached to hair follicles in the skin. When it contracts, usually in response to cold or emotional stimuli, it causes the hair to stand upright, a phenomenon known as piloerection or "goosebumps." This reaction can help insulate the body by trapping air or making the animal appear larger to predators. Additionally, it plays a role in the secretion of sebum from sebaceous glands associated with hair follicles.
