27
Q

Why do we need to understand Histology?

A

• Disease processes affect tissues in distinctive ways, which depend on the type of tissue and the disease itself.

• Understanding the changes that are characteristic of a disease requires detailed knowledge of the normal histology of cells and tissues and the range of normality.

• Knowing the type of tissue and their composition is important in the selection of the appropriate histopathologic technique and stain to be used.

• These changes within cells and tissues can be visualized using histopathologic techniques.

Inability to adapt

A

Cell injury

56
Q

Sever progressive cell injury

A

Irreversible injury

57
Q

Mild transient cell injury

A

Reversible injury

58
Q

• It is through which normal cells handle physiologic demands

• Act of maintaining a steady state

A

HOMEOSTASIS

59
Q

• Changes made by the cell in response to environmental changes (stress or stimuli)

A

ADAPTATION

60
Q

Example: Cell injury or death
Inability to adapt

A

ADAPTATION

61
Q

Altered cell structure or function

A

Cell injury

62
Q

Altered cell structure or function due to:

A

ㅇ Inability to adapt
ㅇ Exposure to injurious stimuli
ㅇDeprivation from essential nutrients

63
Q

Types of cell injury

A

Reversible
Irreversible

64
Q

Physiologic Changes

“Program Cell Death or Active Cell Death”

65
Q

Example of apoptosis

A

Example: death of RBC after 120 days

66
Q

• Pathologic Changes

“Passive Cell Death or Accidental Cell Death”

67
Q

Example of necrosis

A

Example: cell death because of iniurious stimulus

68
Q

STAGES OF THE CELLULAR RESPONSE TO STRESS AND INJURIOUS STIMULI:
OTHER RESPONSES

A

• Autophagy (self-eating)

• Intracellular Accumulation of Substances

• Pathologic Calcification

•Cellular Aging

69
Q

The body will eat its own components in order to survive

A

Autophagy (self-eating)

70
Q

• Acquire substances from neighboring cells

A

Intracellular Accumulation of Substances

71
Q

• The level of calcium is increased; hence, the tissue is hardened.

This happens in order to stop further destruction

A

Pathologic Calcification

72
Q

• The cell is old so the function is already declining.

A

Cellular Aging
