4-6 The arrectores pilorum are bundles of smooth muscle associated with hair follicles. On exposure to cold or under emotion (sympathetic nerves), they elevate the hair in a lever-like manner, and the nearby skin is depressed, whereas the surrounding skin is elevated (goose skin).he follicle is dilated at its base to form the bulb (matrix). In the obtuse angle between the root of a hair and the surface of the skin, a bundle of smooth muscle fibers, known as an arrector pili muscle, is usually found. It extends from the deep part of the hair follicle to the papillary layer of the dermis.
