Goosebumps pop up when tiny muscles at the base of the hair, known as arrector pili muscles, contact and subsequently pull the hair upwards. The reflex is initiated by the sympathetic nervous system, which is responsible for a majority of the fight or flight responses.

The formation of goosebumps in humans is called the vestigial reflex, which raises the hair on the body. The reflex of developing goosebumps is known as the pilomotor reflex, which occurs in many mammals. Porcupines are an excellent example of this. They raise their sharp, spikey quills if they are threatened.

Goosebumps are a result of the reaction that happens on the skin. They are tiny bumps you notice on your skin, and they are formed as a result of the contraction of the muscle at the base of each hair. Goosebumps are caused by so many things, and what determines how long they will appear on your skin has to do with what is causing them. Goosebumps can appear on your skin when you feel excited. For this type, they will remain on your skin as long as you are feeling the excitement.

They also occur as a form of fight or flight response to a dangerous situation. In other animals, when this happens to them, they look bigger than their actual size. You will also notice goosebumps formation on your skin whenever you are feeling cold. During this period, the normal way for your body to regulate itself is by causing the contraction of the muscle at the base of the hair so that your hair will stand up straight.

Goosebumps are raised skin usually caused by the involuntary erection of hairs on the body, mostly on the neck and arms. It is similar to tiny elevations you see on poultry skin when you take off their feathers. Goosebumps are also known as goose pimple, turkey bumps or goose flesh. The medical terminology for goosebump is cutis anserine. When you notice Goosebumps on your skin, it could be that you are cold, or you are experiencing extreme emotions such as fear, shock, excitement, arousal, joy, or sadness. Goosebumps occur when the muscles that are underneath the skin (arrector pili muscles) contract, this pulls the hair on the skin and makes individual hair strand to stand.
