Arrector pili is the muscle the raises hair. This is taught in health class.

arector pili muscle
The arrector pili muscles are in the hair follicles. When contracted, they cause the hair to stand on ends, commonly known as goosebumps.
You have a muscle at the bottom of a hair strand. Your hair itself has no muscles.
It causes erection of hair when stimulated by the sympathetic nervous system.
Pain receptors are bare dendrites that react to a certain type of stimulus. Some pain receptors become activated when extremes of heat or cold cause your skin temperature to rise or fall to dangerous levels. Hope this helps!
No, they attach to the outside of the hair follicle.
Hair is not held in by muscles, but there are muscles that an erect a hair called the "arrector pili muscle".
Piloerector muscles
Yes, the arrector pili muscles contribute to maintaining skin tone. These small muscles are attached to hair follicles and contract in response to various stimuli, causing the hair to stand on end and the skin to form "goosebumps." This contraction helps to firm the skin and provide support.
the number of hair cells that are stimulated
Yes, arrector pili muscles are associated with hair follicles. Arrector pili muscles are in the skin, connected to the hair follicles. Their job is to help maintain body homeostasis. When we are cold, the arrector pili muscles shorten, causing our hairs to stand up so that they block the cold and help keep heat from escaping. Although this is not very effective in humans because evolution has made us less hairy, this is great method for hairy animals to stay warm. Now you know why we get "goosebumps" when we are cold! :)
