goosebumps are the result of an involuntary contraction of erector pilae muscles that are attached to the follicles of hair. They are triggered to contract in order to create an insulating structure when it is cold. Due to a human's lack of hair as compared to other primates, the function of this in temperature regulation is virtually futile.

∙ 15y agoGoosebumps in humans is a vestigial response of piloerection (hair raising) in response to sympathetic stimulation as part of the fight or flight response. This is seen more commonly in cats and dogs where a cat might arch it's back and it's hair stands on end. This makes the cat look bigger and meaner. In people it is much less effective. In terms of a response to the cold piloerection increases the amount air trapped around the body and prevents heat loss.

The structure that contracts to cause goose bumps is the?
Hair follicles. Tiny muscles around them tighten, causing bumps. But the real reason you get goose bumps is that they make your hair stand up straight. This is important, not to humans, anymore, but to animals for two reasons: 1. The standing-up hair is more effective as an insulator, and helps keep the animal warm. This is why goose bumps occur when it is cold. 2. To an enemy, the standing-up hair makes the animal look bigger, and may cause another animal to not attack.
