1. 1- many cytopathologyical specimen are taken to
assess dysplasia
malignancy
infactive pathology
all of the above

2- in immunohistochemistry

this method use antibody

typing poorly differentated tumors

classification of glomerulonephritis

parasitic diagnosis

a and b are true

4- karyotype abnormalities are divided into

numerical and structural
shape
size

5- cusative agents of tissue change in injury are
tumors
thermal injury
poisons
all of the above

6- the mechanism of tissue damage produce by infectious organsim with

metabolic products
vitamins deficiency
secration
a and c are true

7-the effect in tissue will depend on

the duration of injury

the nature of injurious

the ability of tissue to regenerate

all of the above

8-inflammation

usually manifestation of disease

invading of microorgansims

may have benefical effects

all of the above

9- inflammation involves these several processes except

exudative

proliferation
vascular in hyperemia
cell damage

10-causes of acute inflammation are

microbial infection
physical agents
sun light

benign
fat
malignant
a and b are true

12-benign tumors characters as

non invasive

slow grow rate

close histological resemble

13- ischemia is

decrease blood flow to organs


14- benign neoplasia is

extend but not invade local tissue
3. tumor mean

an abnormal infection


swelling or organ enlargement can result from

inflammation

cyst

hyperplasia

all of the above


hypertrophy is

enlargement in individual cell size


matplasia is

replacement of one adult tissue type by another
