Why do most paper cuts and other superficial cuts on your skin not bleed?
-Cuts in a blood vessel need to be wider than the width of a piece of paper in order for a blood vessel to lose blood
-Superficial paper cuts do not bleed because paper is not strong enough to damage blood vessel walls
-Superficial cuts that do not extend past the epidermis do not bleed because the epidermis is avascular.

Many advertisements for skin creams and lotions claim they can rejuvenate our skin by replenishing collagen and elastin. Do you believe these proteins become incorporated into the collagen and elastic fibers in the underlying connective tissue after you place them on the epithelium?
-No, the junctions between multiple layers of epithelial cells do not allow the proteins of skin creams and lotions to penetrate to the underlying connective tissue
-No, collagen and elastin fibers are only found in the epidermis, not the underlying connective tissue
-Yes, there is no reason to doubt an advertisement’s claims.

-Papillary layer
-Reticular layer
What is the function of the papillary layer?
Nourishes and supports the epidermis
What is the function of the reticular layer?
-Has sensory receptors that detect touch, pressure, pain, vibration, and temperature
-Blood vessels assist in thermoregulation
