Skin appendages are skin-associated structures that serve a particular function including sensation, contractility, lubrication and heat loss. In humans, some of the more common skin appendages are hairs (sensation, heat loss, filter for breathing, protection), arrector pilli (smooth muscles that pull hairs straight), sebaceous glands (secrete sebum onto hair follicle, which oils the hair), sweat glands (can be sweat secreted with strong odour (apocrine) or with a faint odour (eccrine)) and nails (protection).
Skin appendages are derived from the skin, and are usually adjacent to it.
Famous quotes containing the words skin and/or appendage:
“Racism as a form of skin worship, and as a sickness and a pathological anxiety for America, is so great, until the poor whites—rather than fighting for jobs or education—fight to remain pink and fight to remain white. And therefore they cannot see an alliance with people that they feel to be inherently inferior.”
—Jesse Jackson (b. 1941)
“... instead of being a help meet to man, in the highest, noblest sense of the term, as a companion, a co-worker, an equal; she has been a mere appendage of his being, an instrument of his convenience and pleasure, the pretty toy with which he wiled [sic] away his leisure moments, or the pet animal whom he humored into playfulness and submission.”
—Angelina Grimké (1805–1879)
