==Key Stage 4==
===Meaning===
A '''erector muscles''' are very small [[muscle]]s at the base of every hair which act to pull the hair to stand on end.
===About Erector Muscles===
: '''Erector muscles''' are used in [[thermoregulation]].
: When the [[Body Temperature|body temperature]] gets too low the '''erector muscles''' contract causing body hairs to stand on end. This creates a pocket of trapped air under the hairs which insulates the body.
: When the [[Body Temperature|body temperature]] gets too high the '''erector muscles''' relax causing body hairs lay flat on the [[skin]].
