1. What is the cellular mechanisms of healing?Involves inflammation, immune cell activity, angiogenesis, and extracellular matrix deposition (collagen)
2. What is the historical medical advancements?Germ theory and aseptic techniques significantly reduced infection-related healing failures
3. What happens when you get a cut?When you get a cut, your body sends immune cells to clean the wound and then fibroblasts lay down collagen to build new tissue. This new tissue helps the wound close and starts to grow new blood vessels and skin cells.
4. Why do some wounds leave scars?Some wounds leave scars because the cells that were damaged can’t make exact copies of the original cells. Fibroblasts then make a strong, but less flexible, scar made of collagen to keep the area stable.

Extracellular Matrix: A network of molecules outside cells that provides structural and biochemical support to surrounding cells.
Angiogenesis: The physiological process through which new blood vessels form from pre-existing ones.
Psychopathological Phenomena: Abnormal or disordered mental states or behaviors associated with mental illness.
