What is vasoconstriction?
This small smooth muscle attached to a hair follicle causes hair to stand up, producing “goosebumps.”
What is the arrector pili?

This is the first stage of wound healing where blood fills the wound and starts to clot.
What is Hemostasis?

What is the Anagen Phase?
These bundles are formed by the orientation of collagen and elastin bundles and are important in surgery to reduce scarring
What are lines of cleavage?
This is the reason a third-degree burn can be life-threatening even if the patient reports little pain at the deepest part of the burn.
What is risk of dehydration/fluid loss? OR What is loss of the protection against pathogens/germs?

What are apocrine sweat glands?
On a skin model, this sensory receptor is located in the papillary dermis and is associated with light touch.
