What do goose bumps do?

Answer 1

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.

Answer 2

Goosebumps 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.

Answer 3

Goose bumps raise the hair on your arm in an attempt to great a thicker layer to protect you in cold weather. It is an evolutionary thing from when we had much thicker hair on your bodies and had to endure cold weather.

Answer 4

Goosebumps are small bumps on the skin which form at the base of hairs on the skin. They occur when we are cold or experience strong emotions such as fear or excitement.

Goosebumps form involuntarily when the tiny muscles at the base of the hair contracts, causing the hair to become more erect. The scientific name for this process is piloerection

the Arrector pili muscle

Answer 5

Goosebumps occur when tiny muscles at the base of each hair follicle contract, causing the hairs to stand up. This response can happen to help keep us warm by trapping air close to the skin or as a response to fear or excitement by making us appear larger.
