EXAM REVIEW QUESTIONS AND
ANSWERS 100% CORRECT
Melanin - ANSWER-Grains of pigment that gives skin & hair its color
Carotene - ANSWER-yellowish pigment from carrots and tomatoes
What are the three layers of skin? - ANSWER-epidermis, dermis, subcutaneous layer
Epidermis is also known as? - ANSWER-the scarfskin and/or the cuticle layer
Keratization - ANSWER-The process of living cells moving upward and changing into
dead cells. (Cell turnover)
What are the two zones of the epidermis? - ANSWER-Horny zone & Germinal Zone
How many layers are in the horny zone - ANSWER-Three
What are the three layers of the Horny zone (epidermis) - ANSWER-Stratum Corneum,
Stratum Lucidum, & Stratum Granulosum
How many layers are in the Germinal Zone? - ANSWER-Two
What are the layers of the Germinal Zone? - ANSWER-Stratum Spinosum & Stratum
Germinativum
stratum corneum - ANSWER-outermost layer of the epidermis, which consists of
flattened, keratinized cells that are bond by sebum
sebum - ANSWER-oily substance secreted by sebaceous glands
stratum lucidum - ANSWER-a layer of the epidermis found only in the thick skin of the
fingers, palms, and soles. Clear layer that allows light to pass through
Eleidin - ANSWER-a transparent, intermediate product of keratin maturation that allows
light to pass through. Found in the stratum lucidum.
stratum granulosum - ANSWER-a layer of the epidermis that marks the transition
between the deeper, metabolically active strata and the dead cells of the more
superficial strata. Persistent friction causes calluses on knees, elbows, & feet.
(Thickness Varies)
, Stratum Spinosum (Prickly Layer) - ANSWER-Several cell layers thick, cells contain a
weblike system of intermediate prekeratin filaments attached to desmosomes.
Keratinocytes appear to have spines and are scattered among abundant melanin
granules and Langerhans' cells. Basal & spinosum together form the germinativum.
What are Langerhans cells? - ANSWER-Located in the Stratum Spinosum, langerhans
cells determine the appropriate adaptive immune response (inflammation or tolerance).
Langerhans cells - ANSWER-Fight infection in the skin due to phagocytosis (eating)
Macrophages - ANSWER-Found within the lymph nodes, they are phagocytes that
destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.
Histology - ANSWER-the study of the microscopic structure of tissues (skin)
List the layers of the epidermis from superficial to deep. - ANSWER-stratum corneum,
stratum lucidum, stratum granulosum, stratum spinosum, stratum basale
List the layers of the epidermis from deep to superficial - ANSWER-stratum basale,
stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum
Dermis - ANSWER-Considered to be true skin. Collagen & elastin is found here.
How many layers are in the dermis? - ANSWER-2, papillary and reticular
papillary layer - ANSWER-Outermost layer of the dermis, directly underneath the
epidermis
Papillary layer consists of - ANSWER-loose connective tissue, dermal papillae,
capillaries, nerve axons
Papillary layer has - ANSWER-Collagenous & reticular fibers that are cone shaped that
protrude upward locking the dermis & epidermis together.
How does skin get its nourishment? - ANSWER-Blood and lymph are the fluids that
nourish the skin.
Capillaries - ANSWER-Microscopic vessel through which exchanges take place
between the blood and cells of the body
Blood supply to the skin - ANSWER-papillary capillaries
papillary capillaries - ANSWER-major blood supply to the skin, that transport oxygen
rich blood, nutrients essential for growth, reproduction and tissue repair of hair, skin, &
nails.
