The arrector pili muscles are activated primarily by cold temperatures and emotional responses, such as fear or anxiety. When exposed to cold, these muscles contract to help retain body heat by causing hair to stand on end, creating an insulating layer. In response to strong emotions, the contraction can lead to "goosebumps," serving as a reflexive mechanism tied to the body's fight-or-flight response.

The structure that contracts to cause goose bumps is the?
Hair follicles. Tiny muscles around them tighten, causing bumps. But the real reason you get goose bumps is that they make your hair stand up straight. This is important, not to humans, anymore, but to animals for two reasons: 1. The standing-up hair is more effective as an insulator, and helps keep the animal warm. This is why goose bumps occur when it is cold. 2. To an enemy, the standing-up hair makes the animal look bigger, and may cause another animal to not attack.

How does skin work to keep us warm in particular the arrector pilli muscle nerve endings and fat lobules?
skin keeps us warm by various mechanisms 1 fat under the skin acts like an insulator and conserves heat 2 erector pilli muscles lead to piloerection which is the erection of the hair on the skin this traps air which acts like an insulator To modify the above answer a little, the raised har traps the air meaning it doesnt move away. Heat from the core of the body is carried in the blood and lost through the skin into the air, if the air is free to move then the heated air is carried away and replaced by cooler air. The presence of the heairs traps the heated air meaning it cant move of and be replaced so the no new cool air has to be heated by loss of body heat. In humans the effect is largely insignificant as the hairs are so far apart air is not really trapped.
