Detailed explanation-1: -Goosebumps occur when tiny muscles in our skin’s hair follicles, called arrector pili muscles, pull hair upright. For animals with thick fur, this response helps keep them warm.
Detailed explanation-2: -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-3: -One of the systems that kick into high gear is the sympathetic nervous system, which then contacts the adrenal glands that release adrenaline to prepare the body for a fight-or-flight response. This response results in involuntary responses throughout the body, such as goosebumps.
