Question

Quizplus · Accepted Answer

Goose bumps (also known as piloerection or gooseflesh) are caused by the contraction of arrector pili muscles. These muscles pull on the hair follicles, which causes the hair to stand on end and creates bumps on the skin. This response is triggered by the sympathetic nervous system, which is responsible for the body's fight or flight response.
