CELLULAR ADAPTATIONS
3 Agents of Cellular Adaptations and its example/s
- Mechanical Agents - TRAUMA
- Physical Agents - UV
- Biological Agents - PARASITES, VIRUSES, BACTERIA
2 Types of Cellular Adaptations
- Adaptation
- Non-adaptation
2 Types of Injury
- Reversible
- Irreversible
These causes cell death
Non-adaptation and Irreversible Injury
Cellular Adaptations (7)
- Atrophy
- Hypertrophy
- Hyperplasia
- Metaplasia
- Anaplasia
- Dysplasia
- Neoplasia
Acquired decreased in tissue or organ size
ATROPHY
2 Types of ATROPHY
- Physiologic
- Pathologic
Type of ATROPHY when the decreasing is NORMAL
PHYSIOLOGIC
Type of ATROPHY when the decrease is due to DISEASE
PATHOLOGIC
Increase in tissue or organ size due to an increase in the size of individual cells that comprise that organ
HYPERTROPHY
3 Types of HYPERTROPHY
- Physiologic
- Pathologic
- Compensatory
Type of HYPERTROPHY when increasing is NORMAL.
PHYSIOLOGIC
Type of HYPERTROPHY when increasing due to DISEASE
PATHOLOGIC
Type of HYPERTROPHY when 1 of the paired organs is removed
COMPENSATORY
Increase in tissue or organ size due to an increase in the number of cells that comprise that organ
HYPERPLASIA
3 Types of HYPERPLASIA
- Physiologic
- Pathologic
- Compensatory
Type of HYPERPLASIA when increasing is NORMAL
PHYSIOLOGIC
Type of HYPERPLASIA when increasing due to DISEASE
PATHOLOGIC
Type of HYPERPLASIA when 1 of the paired organs is removed
COMPENSATORY
Transformation of adult cell into another adult cell type
METAPLASIA
Metaplasia is classified as ____
REVERSIBLE CHANGE
2 Types of Metaplasia
- Epithelial
- Mesenchymal
Epithelial type of Metaplasia involves ___
Epithelial tissue cells
Mesenchymal type of Metaplasia involves ___
Connective tissue cells
Transformation of adult cell into primitive cell type
ANAPLASIA
Anaplasia is classified as _____
IRREVERSIBLE CHANGE
Anaplasia is also known as
DE-DIFFERENTIATION
Characterized by changes in cell size, shape, and orientation
DYSPLASIA
Dysplasia is classified as ____
REVERSIBLE CHANGE
Dysplasia is also known as
ATYPICAL METAPLASIA or PRE-NEOPLASTIC LESION
Process of tumor formation, characterized by abnormal proliferation of cells
NEOPLASIA
Patterns of Cell Death (2)
- APOPTOSIS
- NECROSIS
- Patterns of Cell Death that is PROGRAMMED cell death
- Death of a single cell in a cluster of cells
APOPTOSIS
Apoptosis causes cell to
SHRINK
T/F
In Apoptosis, there is leaking out of cellular contents so there is inflammation
FALSE; NO LEAKING OUT and NO INFLAMMATION
- Patterns of Cell Death that is PATHOLOGIC cell death
- The action of hydrolytic enzymes is blocked
NECROSIS
T/F
In Necrosis, there is NO leaking out of cellular contents there is NO inflammation
FALSE; there IS leaking out and there IS inflammation
T/F
In Necrosis, change can be seen microscopically and grossly
TRUE
Types of Necrosis (5)
- Coagulative
- Liquefactive
- Caseous
- Fat
- Fibrinoid
Type of Necrosis that is due to the sudden cut-off of the blood supply
COAGULATIVE NECROSIS
Coagulative Necrosis happens in solid organs like
KIDNEYS, SPLEEN and LUNGS
The affected organ in Coagulative Necrosis appears like
Gray boiled material
Type of Necrosis that is characterized by complete digestion of cells due to the action of hydrolytic enzymes
LIQUEFACTIVE NECROSIS
The affected organ in Liquefactive Necrosis appears like
liquidly, creamy yellow due to pus
Type of Necrosis that is a combination of Coagulative and Liquefactive
CASEOUS NECROSIS
Caseous necrosis is seen in
TUBERCULOSIS
The affected organ in Caseous Necrosis appears like
“cheese”
Type of Necrosis that is seen in acute pancreatitis, necrotic material
FAT NECROSIS
The affected organ in Fat Necrosis appears like
chalky white precipitates
Type of necrosis seen in immune reactions involving blood vessels
FIBRINOID NECROSIS
Fibrinoid Necrosis changes are so small to see
grossly
It is the death of entire body
SOMATIC DEATH
Changes in Somatic Death
- Primary
- Secondary
Change in Somatic Death that can be noted immediately after death
Primary Changes
Change in Somatic Death that can be noted few hours after death
Secondary Changes
It is removing entire mass/ organ
