True or false: during stressful events, there is decreased blood supply to the skin, which results in "goose bumps."
Sonbull [250]
False.
In a stressful event, there will be a hormone released to the blood called adrenaline. Adrenaline hormone can prepare the body for fight or flight response. One of the effects of this hormone is making the muscle around hair called musculus arrector pili contracted. This contraction of the muscle is what causing the goosebumps. The decreased blood supply has no role in this event.
