15 Questions
What is the primary cause of redness in inflammation?
Inflammatory fluid exudate
What is the main reason for the swelling in inflammation?
Escape of plasma from blood vessels
What causes the pain sensation during inflammation?
Compression by the exudate
What is the contributing factor to the loss of function in inflammation?
Swelling of endothelial cells
Which step is involved in leukocytes extravasation during inflammation?
Chemo-attraction, margination, activation
Which type of tissue renewal involves healing by the same type of cells?
Regeneration
Under what conditions does repair occur?
Severe tissue damage and chronic inflammation
Which type of cells have a short life span and continuous proliferation?
Labile cells
What do permanent cells tend to do under tissue stress?
Increase in size (hypertrophy) or functional capacity
What are the characteristics of stem cells?
Undifferentiated and capable of self-renewal
What is the main difference between regeneration and repair in tissue renewal?
Regeneration involves healing by the same type of cells, while repair involves healing by a mixture of cells and fibrosis.
Which type of cells tend to replicate until reaching adult size and then stop?
Permanent cells
What characterizes stem cells?
They can turn into many types of differentiated cells and self-renew through symmetric division.
Under what conditions does repair occur in tissue renewal?
Severe tissue damage and destruction of connective tissue matrix.
Which type of tissue involves healing by the same type of cells in tissue renewal?
Regeneration
Study Notes
Pathology
- Pathology is the science of disease study, dealing with five components: definition, causes, mechanisms (pathogenesis), morphologic changes (gross and microscopic), and complications.
Inflammation
- Definition: Inflammation is a protective immune-vascular response, a reaction of living tissue against injury.
- Causes of inflammation: infectious agents, immunological, tissue necrosis, chemical and physical agents, and nutritional factors.
Components of Inflammation
- Cause
- Immune cells
- Blood vessels
- Chemical mediators
Purpose of Inflammation
- Eliminate the cause of inflammation
- Clear necrotic cells
- Initiate repair
