goose bumps. pl.n. Momentary roughness of the skin caused by erection of the papillae in response to cold or to a strong emotion, such as fear or awe. Also called goose flesh, goose pimples.
Letâs now look at the mechanics of the goose bump formation. Ordinarily, the hair emerges from the skin at an angle. When the arrector pili muscle fibers contract, this action pulls the lower half of the hair follicle toward the epidermis, resulting in the hair standing more erect. The result of this creates a âbumpingâ of the skin surrounding the shaft of hair above the skin. You now have a goose bump.
