1

types of cellular reaction to any type of injury

???

2

2 types of reversible tissue changes

progressive tissue changes
regressive tissue changes

3

this reversible tissue change usually implies an increase in size

progressive tissue change

4

this reversible tissue change usually implies a decrease in size

regressive tissue change

5

an irreversible change to injury

death

6

Regressive changes (4 types)

Degeneration (intracellular)
Infiltration (intercellular)
Necrosis
Atrophy

7

type of regressive tissue change in which we have the accumulation or buildup of a substance intracellularly within the protoplasm of cells.

Degeneration

8

Types of degeneration

(a) Cellular (cloudy) swelling -

(b) Fatty degeneration -

(c) Amyloid disease - .


9

most common type of degeneration. Similar to edema (excess amounts of tissue fluids which bathe and surround the body cells.) This fluid is between cells. Intracellular, cloudy swelling. The swelling would be transient or temporary.

Cellular (cloudy) swelling -

10

fatty change - fatty metamorphosis – build up or accumulation of fat within the protoplasm of normal cells. Fat in the liver cells affects the liver.
Liver dysfunction

Fatty degeneration

11

accumulation or buildup of amyloid, a waxy starch-like substance within the normal protoplasm of cells. The amyloid is being deposited within the protoplasm of normal cells

Amyloid disease

12

Two most common types of amyloid diseases reported:

TB - Typically, in adults, it begins in the lungs.
Osteomyelitis – inflammation of the spongy bone marrow inside bones.

13

a type of regressive tissue change, in which we have an accumulation or buildup of a substance between the cells

Infiltration (intercellular)

14

What is the difference between degeneration and infiltration?

where the substances are being deposited

15

a type of infiltration; the accumulation of pigmented or colored substance between cells.

Pigmentation

16

pigmentation originated outside the body

Exogenous

17

a color change along the gum line due to lead

plumbism

18

black lung disease

anthracosis

19

the active ingredient of pepto-bismol will cause color change in the small intestines

bismuth poisoning

20

abnormal buildup of a pigmented or colored substance naturally produced within the body, e.g. jaundice, freckles, moles.

Endogenous

21

abnormal accumulation or buildup of calcium salts between cell fibers, as in sclerotic vessels, the way the body heals bone fractures.

Calcification
(calcareous infiltration)

22

abnormal accumulation or excess of uric acid, especially seen in the big toe

Gout

23

types of infiltration (3)

pigmentation
calcification
gout

24

another name for birthmarks

Albenism (albino)

25

a type of regressive tissue change where there is a localized area of dead tissue in the living body.

Necrosis

26

causes of necrosis (4)

(1) Insufficient blood supply.
(2) Physical agent - temperature extremes, radiation.
(3) Chemical agents
(4) Loss of nerve supply

27

types of necrosis (3)

(1) Caseous necrosis

(2) Gangrene

(3) Decubitus ulcer

28

a type of necrosis - Cheeselike in appearance as seen in T.B.

Caseous necrosis

29

ischemic necrosis plus putrefaction

gangrene

30

reduction in arterial blood supply.

Ischemic
