Objectives
- Differentiate the four cellular adaptations — hypertrophy, hyperplasia, atrophy, and metaplasia — by mechanism and clinical context
- Distinguish hypoxia from ischemia and predict how each evolves toward reversible or irreversible injury
- Trace the molecular mechanisms of cell injury through ATP depletion, oxidative stress, calcium overload, and protein misfolding
- Recognize coagulative, liquefactive, caseous, gangrenous, fat, and fibrinoid necrosis on gross and microscopic examination
- Compare the intrinsic and extrinsic pathways of apoptosis and the roles of BCL-2 family proteins and caspases
- Identify autophagy, necroptosis, pyroptosis, and ferroptosis as distinct regulated cell death programs
- Interpret intracellular accumulations of lipids, proteins, glycogen, and pigments as fingerprints of specific diseases
- Differentiate dystrophic from metastatic calcification by setting and clinical implications
- Correlate serum biomarkers of cell death with the morphologic timeline of injury in specific organs
- Apply the framework of adaptation, injury, and death to reason through any pathologic process
Pre Requisites
- Basic understanding of cell biology including organelles and their functions
- Foundational knowledge of biochemistry covering enzymes, ATP, and metabolic pathways
- Familiarity with general histology and basic tissue types
- Introductory exposure to human anatomy and physiology
- Comfort with medical terminology used in basic science courses
FAQ
- Q. How long do I have access to the course materials?
- A. You can view and review the lecture materials indefinitely, like an on-demand channel.
- Q. Can I take my courses with me wherever I go?
- A. Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
