31
Sebaceous glands
In the dermal layer of the skin over the entire body besides soles and palms;
32
Lipids
Group of organic compounds that consist of fat, are greasy to the touch, and are insoluble (incapable of dissolving in water); lubricate the skin and minimize water loss
33
Sweat glands (perspiration)
Coiled glands located in the dermis; found almost all exterior body and they terminate in pores; most abundantly in the palms and soles
34
Sweat glands contains what?
99% water and 1% salt and metabolic waste products
35
Hair (2nd)
Made up of fibers composed of tightly fused, dead proteins cells filled with hard kertain
36
Arrector pili
Bundles of very small muscle fibers; causes the hair on your skin to stand erect (cold or frightened); result in goosebumps
37
Melanocytes surround the core of each..
Hair shaft
38
Nail (3rd)

41
Cuticle
Narrow band of the epidermal tissue attached to the surface of the nail, at the base and sides of the nail plate

Nail root
Area of the dermis on which the nail rest; it fastens the nail to the finger or toe by fitting into a groove in the skin
43
Lunula
Is the semilunar (half-moon-shaped), white area at the proximal end of the nail. The lunula is generally most prominent in the thumbnail
44
Acne
Inflammatory disorder of the sebaceous glands that produce pimples on the skin
