Explanations: answer key for all 10 questions

Q1: Which tiny muscles cause goosebumps?
Answer: Arrector pili
One attaches to each hair follicle.
Q2: What do these muscles do?
Answer: Pull hairs upright
Skin around them bumps up.
Q3: What is the scientific term for raised hairs?
Answer: Piloerection
It is an automatic reflex.
Q4: Which common trigger causes goosebumps?
Answer: Cold
Fear and emotion work too.
Q5: What can moving music sometimes cause?
Answer: Goosebumps or chills
Some call it frisson.
Q6: Which part of the nervous system triggers them?
Answer: The sympathetic nervous system
It handles fight or flight.
Q7: How do raised hairs help furry animals keep warm?
Answer: They trap a layer of warm air
Fluffed fur insulates.
Q8: Why do cats puff up their fur?
Answer: To look bigger to threats
Porcupines raise quills similarly.
Q9: Why are goosebumps less useful in humans?
Answer: We have little body hair
They are a leftover from ancestors.
Q10: What did a 2020 study find about these tiny muscles?
Answer: They help regulate hair growth
Nerves and stem cells were involved.

Tiny Muscles, Big Tingles

Goosebumps happen when tiny arrector pili muscles, one attached to each hair follicle, contract and pull hairs upright. The skin around each hair bumps up, a reflex called piloerection. It is triggered by the sympathetic nervous system, which also handles fight-or-flight responses.

Cold is a common trigger, but fear and strong emotions do it too. Moving music can bring goosebumps or chills, sometimes called frisson. In furry animals, raised hairs trap a layer of warm air, and cats puff up their fur to look bigger to threats, much as porcupines raise their quills.

Humans have little body hair, so goosebumps offer little warmth and are largely a leftover from our ancestors. A 2020 study found these tiny muscles and their nerves also help regulate hair follicle stem cells, playing a role in hair growth.
