Review from lecture exam 1 (Week 8-1 Quiz)

A pulmonary embolus always produces a pulmonary infarction. True False

False

A white infarction usually occurs due to venous obstruction. True False

False

Amniotic fluid and snake venom may induce Disseminated Intravascular Coagulation (DIC) by activating Complement cascade True False

False

Disseminated Intravascular Coagulation (DIC) is a protective mechanism against hemorrhage by strengthening the blood vessels wall with a fibrin clot. True False

False

Fibroblast are very susceptible to the effect of decreased blood flow and die in minutes True False

False

IgE are the antibodies secreted mostly on epithelia True False

False

IgG are the first antibodies secreted in an infection True False

False

Monocytes and limphocytes are the predominant cell found in acute inflammation. True False

False

NK cells are a subset of plasma cells True False

False

Sentinel cells in inflammation are guarding the openings in the epithelia True False

False

Skin that becomes cold and clamy displays major signs of acute inflamation True False

False

The late phase reaction of Type I hypersensitivity reactions is mediatd by vasoactive amines and lipid mediators. True False

False

The mechanism of cardiogenic shock is mainly vascular dilatation that decreases venous return True False

False

There is no proof that mechanical tension applied to a human tissue can alter its cells DNA expression True False

False

Viruses normaly do NOT induce inflamatory response since they are hiden inside the cells True False

False

A complication of shock is the necrosis of intestines producing infection True False

True

A white infarction usually occurs when there is a block of an end artery. True False

True

Abrupt exposure to cold after active vasodilatation will increase capillary permeability potentially leading to chronic inflammation andimmune reactions by increasing intercellular spaces. True False

True

Although known at the beginning of XXth century, fundamental forces and energies including gravity and electromagnetism were ignored in philosophical and scientific models of chiropractic before Dr Parker's time, being replaced by illusory universal forces and innate forces that made chiropractic a pseudoscience or even a cult. True False

True

Although rheumatoid arthritis involves joints predominantly it is also a systemic disease. True False

True

Chemical damage can be induce even by simple, common molecules such as glucose or salt, if they are in hypertonic solutions True False

True

Disseminated intravascular coagulation (DIC) may lead to hemorrhage by consuming platelets and coagulation factors. True False

True

Endothelium can be either anticoagulant or procoagulant depending on the situation. True False

True

Epigenetic factors can alter the chromatin and its expression without changing the DNA sequence True False

True

IgM are the first antibodies secreted in an infection True False

True

Macrophages activation path (M1 to M2) can be changed by mechanical tissue properties (tension, stretch, etc) through epigenetic pathway. True False

True

Mechanical tension can alter DNA expression in certain cells like fibroblasts or endothelial cells, changing their behavior True False

True

Neurons are very susceptible to the effect of decreased blood flow because they do not have the ability to adapt. True False

True

One feature of the skin rash seen in SLE is that it is photosensitive. True False

True

Passive congestion occurs due to venous obstruction. True False

True

Proper correction of tissue tone after an injury will improve healing through epigenetic mechanisms True False

True

Septic shock induces systemic inflammation in addition to peripheral vasodilatation True False

True

The highest risk of death from shock are septic and cardiogenic shock. True False

True

The mechanism of anaphylactic and neurogenic shock is mainly vascular dilatation that decreases venous return True False

True

The mechanism of cardiogenic shock is to directly reduce cardiac output. True False

True

The preformed cell mediators can be released immediately following the injury but only last for about 30 minutes. True False

True

The progression of shock is marked by increased production of lactic acid through anaerobic metabolism True False

True

There is evidence that autoimmune diseases have higher incidence if there was a lack of infections in childhood True False

True

There is evidence that low level of autoimmunity may be induced by the absence of other immune stimuli, so that the immune system stays prepared to act in case of a new infection True False

True

Type III hypersensitivity is mediated by immune complexes True False

True

Venous occlusion of a leg deep vein will result in a warm, swollen leg, with pitting edema True False

True

When acute inflammation causes significant necrosis it will end up producing fibrosis and scar formation. True False

True

Wide spread clotting as seen in Disseminated Intravascular Coagulation (DIC) may be a severe complication in cases like obstetric problems, burns or cancer. True False

True
