3. Degeneration Flashcards
(24 cards)
Apoxia
No oxygen
Hypoxia
Insufficient oxygen
Anemia
def
Ischemia
Insufficient blood supply (due to loss/lack of blood)
Infarction
Death of tissue area, caused by ischemia
Autophagy
Cellular method of adaptation - Sequesters focal injury and old organelles, wrapping them in a vacuole (broken down, or remains as residual body)
Hypertrophy
Increase in cell size
Atrophy
Decreased workload, disuse, decreased blood supply, lack of endocrine stimulation»_space; Decrease in cell size and function
Dystrophy
Faulty nutrition/development»_space; Weakening, defective function
Hyperplasia
Increase in cell number
Hypoplasia
Failure to develop fully
Dysplasia
Abnormal growth/development
Aplasia
No development
Neoplasia
New, progressive growth
Neoplasm
Cell mass composing new growth
Degeneration
def patterns
Apoptosis
Normal, programmed process to eliminate unneeded cells (NO destruction of cell membrane, ATP, NO immune response)
Exhaustion atrophy
def
Necrosis
Lethal injury»_space; enzymes progressively degrade cell»_space; premature cell death
Dystrophic calcification
Calcium salts and other minerals attracted, if necrotic cells and debris aren’t promptly destroyed/reabsorbed
Algor mortis
Postmortem change - Decrease in body temp»_space; body comes to equilibrium w/ enviro
Livor mortis
(2-3 hrs after death) Seepage of blood out of vessels»_space; engorgement of dependent tissues
Rigor mortis
(6-8 hours after death) Rigidity in upper half of body»_space; spreads to lower extremities
Engorgement
Swelling
