PATHO STUDY GUIDE: FINAL EXAM! Stress increases functional demand  adaptations: hypertrophy, hyperplasia, atrophy, metaplasia, dysplasia)  Stress is reversible – when it’s relieved cell returns to normal  Irreversible stress – too much damage  necrosis Reversible Stress Types 1. Atrophy: decreased size of cell due to decreased functional demand  Overall decrease tissue mass  Muscle can atrophy if not used because of injury, neuromuscular dysfunction (i.e. spinal co...

Pathology Concepts Homeostasis • The tendency to maintain balance/stability internally • Self-regulating, give-and-take system • Compensatory mechanisms: strategies that make up for the chan ges and return the body to its normal state • Two feedback systems: - Positive feedback: formation of blood clot while bleeding, child birth - Negative feedback: control of elevated blood sugar by insulin Histology: cause or reason for a disease • May include infectious agents, chemicals, environme...

Chapter 1: PATHOPHYSIOLOGY 370 FINAL EXAM STUDY GUIDE 1. Etiology: study of causes or reasons for a particular injury. Idiopathic (unknown) vs Iatrogenic (unintended/unwanted medical treatment ). Risk Factor: a factor that increases the likelihood of disease. 2. Pathogenesis: development or evolution of disease from initial stimulus to ultimate expression of manifestations of the disease. 3. Clinical Manifestations: Signs (objective) vs Symptoms (subjective). 4. Stages and Clinical Course: Laten...

Chapter 1: Introduction to Pathophysiology Test Bank TRUE/FALSE 1.Normal ranges for physiologic parameters are arbitrarily defined based on population sampling. ANS: T 2. Values outside the no rmal range for a particular variable are always indicative of disease. ANS: F 3. Illness and disease always coexist. ANS: F 4. Normalcy is culturally defined. ANS: T 5. A change in a physiologic variable is more significant than the absolute values. ANS: T 6. Most homeostatic mechanisms function via positi...
