- Passive Insufficiency. The arrector pili muscle, is the small, smooth muscle responsible for producing goose bumps on the skin, also called goose pimples or goose flesh. These small, fan-shaped smooth muscles are located on the side of each hair follicle and contract when exposed to cold, which stimulates the skin to pucker around the pore. The purpose of this, in mammals, is to cause the hairs to stand erect thus providing insulation.
