Review Part 2

Question 1

define Granulomatous Inflammation

Answer 1

a special form of chronic inflammation that is typically is not precede by an acute PMN-mediated inflammation

Question 2

what causes Granulomatous Inflammation

Answer 2

it may be caused by antigens that evoke cell mediated hypersensitivity reaction or by antigens that persist at he site of inflammation

Question 3

prototype Granulomatous Inflammation disease

Answer 3

TB (best example) and other fungal diseases

Question 4

define serous inflammation

Answer 4

mildest form characterized by the erudition of fluid that is clear like serum, occurs at early stages

Question 5

which inflammation is typical of viral infections

Answer 5

serous inflammation, vesicles caused by Herpesvirus

Question 6

Best example of serous inflammation

Answer 6

Herpesvirus or second degree burns

Question 7

Fibrinous Inflammation defintion

Answer 7

exudate that is rich in fibrin formed by long strands of polymerized fibrinogen
fibrin in places such as the heart can effect functioning

Question 8

Example of fibrinous inflammation

Answer 8

bacterial infections such as Strept or pneumonia

Fibrinous Pericarditis

Question 9

Define purulent inflammation

Answer 9

viscous yellow fluid composed of dead and dying PMN’s and necrotic tissue debris

Question 10

what usually causes a purulent inflammation

Answer 10

pus forming bacteria such as staph or strept

Question 11

what is an abscess

Answer 11

a localized collection of pus within an organ or tissue, consist of central portion of purulent material surrounded by a wall composed of a capsule of fibrotic granulation tissue

Question 12

how do abscess heal?

Answer 12

they do not heal spontaneously and must be evacuated. drainage antibiotics

Question 13

what happens with large abscess

Answer 13

they tend to rupture and form a sinus or fistula which are more common in chronic inflammation such as chromes disease

Question 14

What is ulcerative inflammation

Answer 14

inflammation of body surfaces or the mucosa of hollow organs like the stomach or intestines
results in either an ulceration or loss of epithelial innings

Question 15

Pseudomembranous Inflammation

Answer 15

A form of ulcerative inflammation that is combined with fibrinopurulent exudation forms pseudomembrane on the surface of the ulcers that can be scraped away

Question 16

best example of ulcerative inflammation

Answer 16

gastric ulcer

Question 17

best example of Pseudomembranous Inflammation

Answer 17

C difficile pseudomembranous colitis

Question 18

Continuously Dividing Cells

Answer 18

Labile cells, divide throughout the entire lifespan

divide at regular rate and give rise to more differentiated cells. Think skin cells or mucosal ulcers

Question 19

best example of continuously dividing cells

Answer 19

Stem cells, RBC division from bone marrow precursors

Question 20

Quiescent cells

Answer 20

stable cells, can divide if necessary but do not divide regularly, once stable do not divide until needed again

Question 21

Quiescent cells examples

Answer 21

parenchymal organs such as the liver or kidneys

Question 22

Nondividing cells

Answer 22

permanent cells do not have the capacity to proliferate under any circumstances

Question 23

Non dividing cell examples

Answer 23

neurons and myocardial cells, repairs are not functional

Question 24

How does the body compensate for loss of myocardial cells

Answer 24

fibers scarring

Question 25

How does the body compensate for loss of brain cells

Answer 25

Gliosis

Question 26

define keloids

Answer 26

hypertrophic scars composed of predominantly type III collagen defective remodeling of scar tissue, result in immature scar

Question 27

Signs of inflammation

Answer 27

calor, rubor, tumor, dolor, functio laesa

heat, redness, swelling, pain, loss of function
