Muscle Flashcards
1
Q
What happens when muscle is injured (necrosis & regeneration)?
A
- damage => microfibre necrosis
- Inflammation & phagocytosis
- Hypercontration of myofibrils (> stop necrosis/cell death from spreading to rest of cell)
- revascularisation
- Satellite cells activate & proliferate
- fusion of myoblast & myotubules
- re-innercation
- growth & maturation
2
Q
What are satellite cells and their function?
A
muscle-specific stem cells
> facilitate post-natal growth & regeneration:
- activate, proliferate, differentiate & fuse into yofibres
