Medical School MD + DO Mastery

A 4-year, board-aligned study system for medical school and licensing exams.

Walk the full Year 1–4 curriculum — foundational sciences, organ-system blocks, clinical clerkships and advanced practice — each with mastery checklists and linked learning resources, plus a dedicated review system for school exams, Shelf/COMAT, USMLE Step 1–3 and COMLEX-USA Levels 1–3.

PATHOLOGY FOUNDATIONS

YEAR 1 | PAGE 15A - CELL INJURY, INFLAMMATION + REPAIR CONCEPT MASTERY

MECHANISM FIRST

Build general pathology as one causal chain: STRESS/INSULT -> ADAPTATION/REVERSIBLE INJURY -> IRREVERSIBLE INJURY/DEATH -> INFLAMMATION -> RESOLUTION/REPAIR/FIBROSIS. Connect trigger -> mechanism -> morphology -> functional consequence.

1.Cellular Adaptation + Cell Injury - Armando Hasudungan~8 min BONUSHyperplasia, hypertrophy, atrophy, metaplasia and the reversible-to-irreversible injury transition - a concise bridge before deeper pathology.
2.Necrosis and Apoptosis - Osmosis from Elsevier~12 minMechanism and morphology of necrotic vs programmed cell death; use it to predict inflammation and tissue consequences.
3.Inflammation: Vascular Events: Part 1 - Ninja Nerd~34 minMediators, vasodilation, permeability, stasis, margination and the vascular logic behind acute inflammatory findings.
4.Inflammation: Cellular Events: Part 2 - Ninja Nerd~21 minLeukocyte rolling/adhesion/transmigration, chemotaxis, phagocytosis, opsonization and killing - mechanism to morphology.
5.Wound Healing - Osmosis from Elsevier~10 minHemostasis -> inflammation -> epithelialization/fibroplasia -> maturation; primary, secondary and tertiary intention plus impaired healing.
6.Free Radicals and Cellular Injury - Osmosis from Elsevier~8 min BONUSROS generation, lipid/protein/DNA injury, antioxidant defenses, metals and reperfusion injury - a recurring cell-injury mechanism.

  • Classify hyperplasia, hypertrophy, atrophy and metaplasia; distinguish reversible from irreversible injury.
  • Link ATP depletion, calcium influx, ROS, mitochondrial damage and membrane injury to morphology and function.
  • Distinguish major necrosis patterns from apoptosis and predict the inflammatory response.
  • Reconstruct acute inflammation and wound repair; explain regeneration vs fibrosis and factors that impair healing. VIDEO-FIRST | SCHOOL-EXAM + BOARD-EXAM MASTERY
