NU673 Final Exam Questions with
Accurate. 100% success
o Basal cell carcinoma (BCC)
o Squamous cell carcinoma (SCC)
o Melanoma (most lethal) - ✔✔name the 3 major skin cancers
basal cell carcinoma - ✔✔80% of skin cancers
Shiny and translucent, they grow slowly and rarely metastasize
squamous cell carcinoma - ✔✔Comprises 16% of skin cancers
Crusted, scaly, and ulcerated, they can metastasize
melanoma - ✔✔Comprises 4% of skin cancers
Rapidly increasing in frequency, they spread rapidly
Epidermis - ✔✔Thin, avascular keratinized epithelium consisting of the outer stratum corneum
and an inner cellular layer, the stratum basale and the stratum spinosum.
Dermis - ✔✔Dense layer of interconnecting collagen and elastic fibers containing sebaceous
glands, sweat glands, hair follicles and most of the terminals of the cutaneous nerves.
subcutaneous tissues - ✔✔also known as fatty tissue
Cyanosis - ✔✔can indicate decreased oxygen in the blood or decreased blood flow in response
to a cold environment.
,sebaceous glands - ✔✔produce a fatty substance secreted onto the skin surface through the
hair follicles. These glands are present on all skin surfaces except the palms and soles
Eccrine glands - ✔✔widely distributed, open directly onto the skin surface, and by their sweat
production help to control body temp.
apocrine glands - ✔✔found chiefly in the axillary and genital regions and usually open into hair
follicles. Responsible for adult body odor.
o Asymmetry
o Border irregularity
o Color variations
o Diameter >6mm
o Evolving or changing rapidly in size, symptoms, or morphology
o EFG- elevated, firm, growing - ✔✔ABCDE rule
necrosis - ✔✔Local redness of the skin warns of impending _______
PAD - ✔✔atherosclerotic disease distal to the aortic bifurction
Intima - ✔✔Surrounds the lumen of all blood vessels; it is a single continuous lining of
endothelial cells.
Produced molecules such as Willebrand factor and plasminogen activator inhibitor.
Modulates blood flow and vascular reactivity
Regulates immune and inflammatory reactions
, Media - ✔✔Composed of smooth muscle cells that dilate and constrict to accommodate blood
pressure and flow.
Adventitia - ✔✔The outer layer of the artery; connective tissue contacting nerve fibers and the
vasa vasorum.
atherosclerosis - ✔✔a chronic inflammatory disease initiated by injury to vascular endothelial
cells, provoking atheromatous plaque formation and the vascular lesions of HTN.
collateral circulation - ✔✔if a major artery is obstructed, anastomoses between branching
networks of smaller arteries can increase in size over time; perfuses structures distal to the
occlusion.
mesenteric arteries - ✔✔Occlusion of the _______ can result in bowel ischemia and infarction
(small and large intestines)
veins - ✔✔Can contain up to two thirds of circulating blood
Venules - ✔✔drain capillary beds and form interconnecting venous plexus such as the rectal
venous plexuses.
lymphatic system - ✔✔An extensive vascular network that drains lymph fluid from body tissues
and returns it to the venous circulation.
originates in the extracellular spaces
Cappilaries - ✔✔collect tissue fluid plasma proteins, cells, and cellular debris via their porous
endothelium.
