MOD 4 Healing & Repair Flashcards
When a tissue are damaged by what two mechanisms can healing occurs by?
Fibrous repair and regeneration
What is meant by regeneration?
The replacement of dead/damaged cells by cells of the same type (DIFFERENTIATED & FUNCTIONAL) by mitosis or from stem cell asymmetric division . Normal tissue structure is restored.
What is meant by resolution?
The complete return of a tissue to how it was before damage.
