A

Psychogenic Disease

21
Q

Anything that causes harm to the patient

A

Iatrogenic cause

22
Q

A cell injury that means “of unknown cause”

A

Idiopathic diseases

23
Q

one of the great Greek physicians, along with Erasistratus, provided a beginning for anatomical pathology and autopsy

A

Herophilus

24
Q

The replacement of one differentiated somatic cell type with another differentiated somatic cell type in the same tissue

A

Metaplasia

25
Q

Conversion in cell type

A

Metaplasia

26
Q

Occur in the epithelial and mesenchymal cells

A

Metaplasia

27
Q

It occur due to external stimulus

A

Metaplasia

28
Q

Reversible on withdrawal

A

Metaplasia

29
Q

Disorder cellular development

A

Dysplasia

30
Q

Changes in the phenotype cells

A

Dysplasia

31
Q

Occur due to the alteration of the genetic material

A

Dysplasia

32
Q

It may regress on removing the stimulus or may progress to high grade dysplasia

A

Dysplasia

33
Q

Various mechanisms which involved in adaptive cellular responses include the following:

A
  1. Altered cells surface receptor binding
  2. Alterations in signal for protein synthesis
  3. Synthesis of new proteins by the target cells such as heat shock proteins.
34
Q

Results in a build up of decomposing dead tissue and cell debris at or near the site of the cell death.

A

Untreated necrosis

35
Q

The death of body tissue.

A

Necrosis

36
Q

A procedure necessary to remove necrotic tissue surgically

A

debridement

37
Q

Types of Necrosis

A
  1. Coagulative necrosis
  2. Colliquative necrosis
  3. Caseous necrosis
  4. Gangrenous necrosis
  5. Fibrinoid necrosis
  6. Fat necrosis
38
Q

Formation of a gelatinous substance in dead tissues in which the architecture of the tissue is maintained and can be observed by light microscopy. Occurs as the result of protein denaturation causing albumin to transform into firm and opaque state.

A

Coagulative necrosis

39
Q

Cell undergo lysis rapidly in contrast to coagulative necrosis, is characterized by the digestion of dead cells to form a viscous liquid mass.

A

Colliquative

40
Q

Infection with Mycobacterium tuberculosis which interacts with macrophages. The necrotic tissue appears white and friable, like clumped cheese.

A

Caseous Necrosis

41
Q

Necrosis to the appendage. Usually the limbs

A

Gangrenous Necrosis

42
Q

Is a special form of necrosis usually caused by immune mediated vascular damage smooth muscle necrosis, fibrin release ( malignant Hypertension)

A

Fibrinoid Necrosis

43
Q

Is a specialized necrosis of fat tissues resulting from the action of activated lipase on fatty tissue such as the pancreas

A

Fat Necrosis

44
Q

Nuclear changes related to necrosis

A
  1. Margination of chromatin
  2. Pyknosis
  3. Karyolysis
  4. Karyorrhexis
45
Q

Chromatin condensing around the periphery of the nucleus

A

Margination of chromatin

46
Q

Small and dense nuclei

A

Pyknosis

47
Q

Complete lysis of the nuclei

A

Karyolysis

48
Q

Nuclei fragmentation ( generally seen in apoptosis)

A
