Goose flesh. Macrophotograph of human skin showing goose flesh. This occurs when the person is cold or frightened. Tiny muscles by the hairs pull them upright, raising the skin at their base and giving it the appearance of plucked goose skin. This traps air close to the skin, which decreases heat loss. Magnification: x4 at 35mm size.
