Study Notes
Cell Injury and Response
- Reversible response to cell injury: cellular adaptation
- Physiological cause of hyperplasia: increased demand or stimuli
Cell Death
- Main difference between necrosis and apoptosis: necrosis is uncontrolled and apoptosis is controlled
- Type of necrosis characterized by transformation of solid tissue into a liquid mass and complete digestion of dead cells: liquefactive necrosis
- Type of necrosis characterized by a distinctive cheesy, crumbly, white gross appearance and commonly associated with tuberculous infection: caseous necrosis
- Type of necrosis characterized by preservation of cell shape and organ structure, with disappearance of nuclei: coagulative necrosis
- Type of necrosis associated with necrotic damage to blood vessel walls and often occurs in the context of vasculitis: fibrinoid necrosis
Cellular Adaptation
- Example of metaplasia: replacement of one type of epithelium with another
- Cause of cell injury: genetic mutation, infection, toxins, etc.
Irreversible Cellular Injury
- Consequence of irreversible cellular injury: cell death or necrosis
Membrane Damage
- Role of free radicals in membrane damage: disrupts membrane structure and function
Acute Inflammation
- Characteristic of acute inflammation: rapid onset, short duration
- Two major events in acute inflammation: increased blood flow and increased permeability
- Five classic signs of acute inflammation: redness, swelling, heat, pain, and loss of function
- Characteristic of exudate: fluid rich in protein and cells
- Function of neutrophils' tertiary granules: antibacterial properties
- Role of reactive oxygen species in neutrophils: bactericidal effects
- Function of vasoactive amines: regulate blood flow and permeability
Cell Division
- Type of cell division that gives rise to sperm and egg cells: meiosis
- Chromosome number in diploid human cells: 46
Inheritance Patterns
- Inheritance pattern characterized by the interaction of several genes: polygenic inheritance
- Type of inheritance that is not Mendelian: polygenic inheritance
- Difference between multi-gene (polygenic) defects and Mendelian inheritance patterns: multiple genes contribute to the phenotype in polygenic inheritance
- Process responsible for generating genetic diversity in Meiosis I: crossing over
- End result of DNA replication: two identical daughter molecules
Miscellaneous
- Term used to describe the physical appearance of an organism based on its genetic constitution: phenotype
