‭Directions:‬‭Match the description in Column A with‬‭the appropriate term in Column B.‬
‭Write the correct letter on the line provided.‬
‭Column A‬
‭1.‬ ‭____The lower thicker layer of the dermis.‬
‭Column B‬
‭A.‬ ‭Epidermis‬
‭2.‬ ‭____Outer layer of our skin, avascular, protects body from the environment‬ ‭B.‬ ‭Dermis‬
‭3.‬ ‭____Protects skin from harmful UV rays‬
‭C.‬ ‭Hypodermis‬
‭4.‬ ‭____Bottom layer of epidermis; contains living, dividing cells that get‬
‭pushed up to higher layers.‬
‭D.‬ ‭Stratum Corneum(2)‬
‭5.‬ ‭____Hard fibrous protein found in epidermal cells, hair, and nails.‬
‭F.‬ ‭Papillary Layer(2)‬
‭6.‬ ‭____Phase of wound healing, vasodilation occurs increasing blood flow,‬
‭white blood cells fight off infection & clear debris.‬
‭G.‬ ‭Reticular Layer(2)‬
‭7.‬ ‭____The outermost layer of the epidermis, containing dead cells.‬
‭I.‬ ‭Sebaceous Gland‬
‭8.‬ ‭____Structure responsible for producing the hair.‬
‭J.‬ ‭Arrector Pili Muscle‬
‭9.‬ ‭____Used to provide nutrients, remove wastes, and regulate temperature.‬
‭K.‬ ‭Blood vessels‬
‭10.‬‭____Specific layer consisting of dense irregular connective tissue‬
‭containing collagen and elastin fibers.‬
‭L.‬ ‭Hair follicle‬
‭11.‬‭____Produces and secretes a thick oily substance.‬
‭N.‬ ‭Hair root‬
‭12.‬‭____The upper, thinner layer of the dermis.‬
‭O.‬ ‭Hemostasis‬
‭13.‬‭____Protrudes from the skin surface.‬
‭P.‬ ‭Inflammatory‬
‭14.‬‭____Secretes a liquid that functions to eliminate excess body heat.‬
‭Q.‬ ‭Proliferation‬
‭15.‬‭____Cells that produce the pigment Melanin.‬
‭R.‬ R
‭ emodeling/‬
‭Maturation‬
‭16.‬‭____Phase of wound healing where the wound is filled in and rebuilt with‬
‭new epithelial tissue. Wound contracts as new tissues are built.‬
‭S.‬ ‭Keratinocytes‬
‭17.‬‭____Epidermal cells that produce keratin.‬
‭18.‬‭____Contracts to make hair stand up, usually in response to a decrease in‬
‭internal body temperature.‬
‭19.‬‭____The part of the hair implanted in the skin‬
‭20.‬‭____Specific layer where Melanocytes are found‬
‭21.‬‭____Specific layer containing Keratinocytes‬
‭22.‬‭____Phase of wound healing where collagen in new epithelial tissue is‬
‭reorganized, making it gradually stronger and more flexible over time.‬
‭23.‬‭____Stores fat, protects from mechanical injuries, connects skin to‬
‭underlying tissues.‬
‭24.‬‭____Specific layer with an uneven surface and is made up of Areolar tissue‬
‭(loose connective tissue with thin & relatively sparse collagen fibers)‬
‭25.‬‭____Phase of wound healing where vasoconstriction & clotting occurs‬
‭26.‬‭____The thick layer of the skin below the epidermis.‬
‭E.‬ ‭Stratum Basale(2)‬
‭H.‬ ‭Sweat Glands‬
‭M.‬ ‭Hair shaft‬
‭T.‬ ‭Keratin‬
‭U.‬ ‭Melanocytes‬
‭V.‬ ‭Melanin‬
