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
