melanocytes
21. False - (ANSWER)The skin is not able to receive stimuli because the cells of the
epidermis are not living and therefore there are no sensory receptors in the skin

diagnosis
24. False (This happens when you work out) - (ANSWER)When an individual is exposed
to extremely cold air the dermal blood vessels will dilate so that more blood will be
brought closer to the outside surface of the skin

thick and protective
27. True - (ANSWER)The pinkish hue of individuals with fair skin is the result of the
crimson color of oxygenated hemoglobin (contained in red blood cells) circulating in
the dermal capillaries and reflecting through the epidermis
