Cancer. Inflammation. Healing. Immunity. Flashcards
What types of cells do become cancerous?
Blood, skin, and liver, bone (parent or progenitor cells)
What types do not become cancerous ?
Well-Differenced (skeletal and cardiac muscle)
-sacroma and -carcionoma indicate
Malignant tumor
Anaplasia
Loss of cellular differentiation
Excessive cellular proliferation
Autonomy
What must become mutated to become oncogenes?
Protooncogenes
Paraneoplastic Syndrome
Tumors release substances that affect neurologic function by mimicking hormones
The best way to diagnose cancer?
Biopsy
3 purposes of Inflammation?
- neutralize
- limit spread
- prepare repair
First responders injury?
Neutrophils
Local effects inflammation
Redness, swelling, heat, pain, loss of function
Systemic Effects of inflammation
mild fever, malaise, fatigue, headache, anorexia/weight loss
Controls of fever (2)
Hypothalamus and pyrogens
When does C-Reactive appear in CBC?
With acute inflammation and necrosis
ESR
elevated erythrocyte sentiment rate indicates increase rate at which RBC settle
Shift to the left
Increase in Bands (= immature neutrophils) indicating BACTERIAL infection
Increased lymphocytes indicate
VIRAL infection
Leukocytosis indicates
inflammation
Resolution healing
minimal tissue damage
Regeneration
Damaged tissue replaced by functional tissue
Replacement
Functional tissue is replaced by scar tissue
Hypertrophic scar tissue
Fibrous tissue with lots of collagen deposits
Ex: keloid formation
Ulcerations
Cause further tissue breakdown and impairs blood supply to the area
MHC 1
On all nucleated cells to prevent immune cells from destroying self cells
