Detailed explanation-1: -Goosebumps are the result of tiny muscles flexing in the skin, making hair follicles rise up a bit. This causes hairs to stand up. Goosebumps are an involuntary reaction: nerves from the sympathetic nervous system-the nerves that control the fight or flight response-control these skin muscles.
Detailed explanation-2: -Arrector pili muscles attach to the bulge region of hair follicles where hair follicle stem cells (HFSCs) reside. Arrector pili muscles are enwrapped by sympathetic pilomotor nerves, which release the neurotransmitter norepinephrine (NE) to trigger muscle contraction and cause hairs to become erect in response to cold.
Detailed explanation-3: -The stimulus of cold surroundings causes the tiny muscles (arrector pili muscle) attached to each hair follicle to contract.
