Cellular Degeneration
Karyolysis:nuclearrupturing/fading/destructionKaryorrhexis:nuclear swellingPyknosis:nuclear condensationAll the above = “nuclear dissolution”leads to ananuclear necrotic cell
Developmental Changes
Agenesis: absence of organ (usually paired organs; renal, testicular.. odontoid)Aplasia: small remnants of the organ, lack of developmentHypoplasia: smaller than normal, usually defective
Primary PathologyvsSecondary Pathology
Primary
* arrives spontaneously organ in question is fucked up
Secondary
* usually insidious
* resultant from other trauma/pathology organ in question is malfunctioning, due to some other organ not working properly
Growth DisturbancesCancer
Metaplasia: functional change fromone cell type to anotherDysplasia:change in size/shape/fx,precancerous, but last stage that can be returned to normalAnaplasia:complete disorganization of a cell (cancer)squamous cell carcinoma
