HMB202H1 Lecture Notes - Lecture 1: Caseous Necrosis, Coagulative Necrosis, Cream Cheese
Document Summary
Successful -cell return to normal or cell adapt. Unsuccessful cell death or neoplasia (uncontrolled growth of cells) Key atlas findings: income and rates of diabetes. Rural areas: highest rate of diabetes, transportation relies on car, least activity. Urban areas: lower rate of diabetes, transportation relies on walking, more access to gym and programs. A damage that show abnormality, can be caused by pathogens or nature of the body. Body"s reaction to deregulations -environment can also act as an outer force. Disease is body"s normal response towards extreme stress. Etiology- the cause (including nature) to disease. Further progression in disease = more irreversible. If not, necrosis or apoptosis: selective damage (e. g. dna, mitochondria, cell surface) programmed cell death apoptosis, non-lethal damage (e. g. mutation) dysplasia neoplasia. Coagulative necrosis: dead tissue; firm, recognizable structure, jelly like. Colliquative necrosis: dead tissue; semi-liquid, unable to recognize structure. Caseous necrosis: dead tissue; soft, friable, cream cheese like consistency, white/grey clump.
