Study Notes
Cell Proliferation and Types
- Regeneration occurs through the proliferation of surviving cells with regenerative capacity.
- Mature tissues consist of three cell types based on their relationship to the cell cycle:
- Continuously dividing cells (labile cells) that are always in the cell cycle.
- Quiescent cells (stable cells) that can re-enter the cell cycle occasionally.
- Non-dividing cells (permanent cells) that do not proliferate post-maturity.
Healing Processes
- Healing can occur through:
- Regeneration of tissues from surviving cells.
- Repair processes involving scar formation.
- A combination of both regeneration and repair methods.
Inflammatory Response
- Tissue injury triggers an inflammatory reaction aimed at:
- Limiting damage and facilitating the removal of injured tissue.
- Prompting healing processes to initiate recovery.
Response to Injury
- Mild and transient injuries typically result in a direct regenerative response, allowing effective recovery without significant scarring.
