NR 507 Final
Innate Immunity - Answer-Is in place at birth to prevent damage by substances in the environment and
thwart infection by pathogenic microorganisms
Two Types of Innate Immunity - Answer-Natural Barriers (physical, mechanical, and biochemical) and
Inflammation
Adaptive (Acquired) Immunity - Answer-Third line of defense that is initiated when innate immune
system signals the cells of adaptive immunity. Responsive toward a very specific antigen. Develops
slowly during first exposure, but is immediate at second exposure.
Cells of Adaptive Immunity - Answer-T Lymphocytes, B lymphocytes, macrophages, dendritic cells
Cells of Innate Immunity - Answer-Mast cells, granulocytes (neutrophils, eosinophils, basophils), Natural
Killer cells, platelets, and endothelial cells
The relationship between arterial perfusion and alveolar gas pressure at the base of the lungs - Answer-
arterial perfusion pressure exceeds alveolar gas pressure
When an individual is in an upright position - Answer-gravity pulls the lungs down toward the
diaphragm and compresses the bases of the lungs
, Psoriasis, pityriasis rosea, lichen planus - Answer-inflammatory disorders characterized by papules,
scales, plaques, and erythema
Psoriasis - Answer-chronic, relapsing, proliferative, inflammatory disorder that involves skin, scalp, and
nails. It can occur at any age
Pityriasis rosea - Answer-benign, self-limiting inflammatory disorder that occurs more often in young
adults. Peaks in the spring and the fall. The cause is unknown, but it is associated with a virus.
Pityriasis rosea symptoms - Answer-begins as a single lesion (herald patch) that is circular, demarcated,
and salmon-pink. Usually located on the trunk.
Lichen Planus - Answer-benign, autoimmune, inflammatory disorder of the skin and mucous
membranes. Linked to Hepatitis C, drugs, and film-processing chemicals. Age of onset is usually 30-70
years old
Lichen Planus Symptoms - Answer-begins with flat, purple, polygonal, pruitic, nonscaling papules.
Usually located on the wrists, ankles, lower legs, and genitalia. New lesions are pale pink and develop
into a dark violet. Persistent lesions become thickened and red (hypertrophic LP). Oral lesions are lacy
white rings and may be precancerous lesions
Croup - Answer-infection and obstruction of the upper airways. most commonly occurs in children from
6 months to 3 years of age (peak at 2yo). Highest incidence in the autumn and winter (parainfluenza and
RSV seasons). More common in boys than girls.
Chickenpox - Answer-Produced by varicella-zoster virus (VZV). Inbubation time is 10-27 days (avg 14).
Productive infection occurs within keratinocytes such that vesicular lesions occur in the epidermis, and
an inflammatory inflitrate is often present.
