WILEY PLUS EXAM 2 QUESTIONS AND
ANSWERS WITH VERIFIED SOLUTION
100% CORRECT!!!
Phase 1: Hemostasis Phase. Phase 2: Defensive/Inflammatory Phase. Phase 3:
Proliferative Phase. Phase 4: Maturation Phase. - ANSWER✔✔Briefly describe
the steps in deep wound healing.
Epidermis - ANSWER✔✔Which layer of the skin is composed of a keratinized
stratified squamous epithelium?
John has lost approximately 27% of the skin's surface area (according to the Rule
of Nines), which leads to severe systemic effects. The epidermis, dermis,
subcutaneous layer and associated structures have been destroyed. Sensory
function is lost. Loss of epidermis (and so, lost keratin and Langerhans cells)
makes John susceptible to microbial invasion. Loss of keratinized structures and
lamellar granules allows for extreme loss of water, plasma, and plasma proteins,
which causes shock; leading to dehydration, reduced blood volume and circulation,
decreased urine output and diminished immune responses. - ANSWER✔✔John
has just been brought into the emergency room following a fiery explosion at a
chemical plant. He is diagnosed with third degree burns over the anterior surfaces
of his arms and trunk. What specific structural damage has occurred to his skin?
What risks to John's life have resulted from this damage?
action of arrector pili muscles - ANSWER✔✔"Goose bumps" are caused by
Hypodermis - ANSWER✔✔Another name for the subcutaneous layer is
Pallor - ANSWER✔✔Which of the following terms refers to paleness of the skin
such as seen in patients with shock or anemia?
,Melanin - ANSWER✔✔Albinism is the inherited inability to produce
Stratum corneum - ANSWER✔✔Protective layer; outermost 20-30 dead
keratinocytes of epidermis; rubs off as dandruff
Ectoderm - ANSWER✔✔From which of the primary germ layers of the embryo
does the epidermis of the skin develop?
thin skin has thinner epidermis, thin skin has no stratum lucidum, thin skin
CONTAINS HAIR FOLLICLES - ANSWER✔✔Describe the major differences
between thin skin and thick skin
Keloid scar - ANSWER✔✔In which type of scar does the scar tissue extend
beyond the boundary of the injury into normal tissue?
Hives - ANSWER✔✔Which of the following terms refers to reddened, elevated,
and itchy patches of skin commonly caused by emotional stress, physical trauma,
or certain food allergies?
eczema - ANSWER✔✔Which of the following terms refers to an inflammation of
the skin characterized by patches of redness, blistering, and extreme itching?
absorbs UV radiation, prevents damage to epidermal cell DNA, and neutralizes
free radicals - ANSWER✔✔what are the three functions of melanin?
, Contain epidermal ridges, contain more sweat glands than thin skin, does not have
hair follicles, and found in palms, soles of feet, and fingertips -
ANSWER✔✔Characteristics of thick skin include:
Dermis - ANSWER✔✔Which layer of the skin is composed mainly of dense
irregular connective tissue containing collagen and elastic fibers?
Papillary Layer; ducts of sweat glands open up the tops of epidermal ridges as
sweat pores - ANSWER✔✔What structure generates fingerprints?
eccrine sweat gland - ANSWER✔✔Which type of exocrine gland is a simple,
coiled tubular gland that is found throughout almost the entirety of the skin?
Oil glands - ANSWER✔✔Which of the following structures found in the skin help
prevent water loss and inhibit bacterial growth on the surface of the skin?
Sebum - ANSWER✔✔Which of the following is a mixture of triglycerides,
cholesterol, proteins and inorganic salts?
Maintains body temperature, acts as a surface to get rid of heat, converts inactive
vitamin D, provides sensory information, and maintains homeostasis -
ANSWER✔✔List and briefly describe the major functions of the skin
Callus - ANSWER✔✔Which of the following terms refers to a hardened and
thickened area of skin resulting from persistent pressure and friction?
Sebaceous gland - ANSWER✔✔This type of exocrine gland is a simple, branched
acinar gland connected to a hair follicle
