I lurve gooseberms!


Mine come out when my ulcer hurts. figure that one out.

I was told it was because air is a good thermal insulator, so the hairs stand up to have more air trapped around them and provide additional thermal insulation for the skin. That would explain goosebumps in response to cold.

Goose bumps are created when tiny muscles at the base of each hair, known as arrectores pilorum, contract and pull the hair erect. The reflex is started by the sympathetic nervous system, which is responsible for many fight-or-flight responses.

During the formation of goose bumps, the body is warmed from the muscle tension in piloerection.

As a response to cold: in animals covered with fur or hair, the erect hairs trap air to create a layer of insulation. Goose bumps can also be a response to anger or fear: the erect hairs make the animal appear larger, in order to intimidate enemies.

ulcer pain sounds like an intensely stimulating trigger of sharp pain... i seem to remember goosebumps while getting a tattoo
