Q

ability of a tissue or organ to adapt to an injury/stress

the potential for regeneration is dictated by what 3 cell populations?

A

Labile cells, Stable cells, Permanent cells

22
Q

ability of a tissue or organ to adapt to an injury/stress

Labile cells are ____
give an example

potential for regeneration

A

a continuously renewing cell population
ex: anything epithelium

23
Q

ability of a tissue or organ to adapt to an injury/stress

Stable cells are ____
give an example

potential for regeneration

A

a (potentially) expanding cell population
ex: (stem cells) Hepatocytes + anything “blast”

potentially = requires signal

24
Q

ability of a tissue or organ to adapt to an injury/stress

Permanent cells are ____
give an example

potential for regeneration

A

a static cell population
ex: striated Mm. + CNS neurons

25
Q

Cells can adapt through modulation of their ____

A

size, shape, metabolism, + behavior

26
Q

the major forms of cellular adaptation are:

(5)

A

Atrophy, Hyperatrophy, Hyperplasia, Metaplasia, Dysplasia

27
Q

Atrophy

A

tissues/cells decrease in size

28
Q

____ is an adaptation to diminished need or resources for a cell’s activities

A

Atrophy

29
Q

Atrophy refers to the ____ of a cell or organ due to ____

A

shrinkage; loss of organelles

30
Q

Atrophy involves changes both in ____ + ____ of cellular constituents. In it’s most basic sense, atrophy is a cell’s reversible restructuring of its activities to facilitate its own survival and adapt to conditions of ____ use.

A

production + destruction
diminished

31
Q

Physiological atrophy

A

normal loss of endocrine stimulation

32
Q

Give an example of Physiological atrophy

A

muscles aren’t being used = couch potato

33
Q

Pathological atrophy

A

diminished blood supply, inadequate nutrition, loss of innervation, abnormal loss of endocrine stim., decreased workload

34
Q

Give an example of Pathological atrophy

A

Atherosclerosis; heart failure

35
Q

Pathological atrophy is caused by a ___/___/___

A

disease/illness/condition (these are reversible conditions)

36
Q

Can a case be made for both physiological and/or pathological atrophy of the Cerebral cortex? give an example than can cause this

A

no, only Pathological;
Dementia, lack of blood supply to brain

37
Q

Hypertrophy

A

increase cell size and functional capacity

38
Q

____ is due to an increase in production and # of intracellular organelles (increased metabolic demands on the cell/hormonal stim.)

A

Hypertrophy

39
Q

Physiological hypertrophy

A

increased functional demand

40
Q

give an example of Physiological hypertrophy

A

couch potato starts lifting again

41
Q

Pathological hypertrophy

A

goiter
hyperactivity of an endocrine gland
hormone-secreting tumor = hyperactivity of an endocrine gland
excessive abnormal demands on an organ: ie myocardial hypertrophy due to valve damage hypertension

42
Q

give an example of Pathological hypertrophy

A

Hypertension (increased BP), Atherosclerosis, hormone secreting tumor
= heart hypertrophy due to increased work of heart to get blood to flow

43
Q

Can a case be made for both physiological and/or pathological hypertrophy of an enlarged heart?

A

no, Pathological only

44
Q

Hyperplasia

A

increase in # of cells = increase in size of organ/tissue
(increased functional and/or metabolic demands on the cell or compensatory proliferation

45
Q

give examples of Physiological hyperplasia

A

hormonal stimulation (lactating breast)
increase RBCs at high altitude

46
Q

give examples of Pathological hyperplasia

A

Endometriosis, psoriasis, liver regeneration following damage (live liver donor b/c completely regenerates itself in 6 weeks)

47
Q

Surgery is always ____

A

Pathologic

48
Q

Metaplasia

A

substitute one cell type for another

49
Q

Metaplasia is a response to ____

A

persistent injury/irritation

50
Q

Though not restricted to squamous differentiation, Metaplasia is commonly ____ replaced by ____

A

glandular epithelium replaced by squamous epithelium

51
Q

give examples of Metaplasia

A

Squamous metaplasia (bronchus, bladder) (smokers)
Barret esophagus
Myositis ossificans

52
Q

what is Myositis ossificans?

A

soft tissue begins behaving like bone
