| − | *Different types of degeneration
| |
| − | *May, or may not, be reversible
| |
| − | *Cloudy swelling, hydropic, vacuolar, granular and fatty change
| |
| − | *Occur following many different types of insult and are usually '''segmental'''
| |
| − | *If regeneration does not occur after formation of small vacuoles, [[Muscles Degenerative - Pathology#Necrosis|necrosis]] follows
| |
| − | **Vacuolation -> floccular degeneration -> granular degeneration -> [[Hyaline Degeneration|hyaline]] and [[Zenker Degeneration - Pathology|Zenker’s degeneration]]
| |
| − | *[[Hydropic Degeneration#Vacuolar Degeneration|'''Vacuolar degeneration''']]:
| |
| − | **Due to swelling of organelles or due to glycogen or fat accumulation
| |
| − | **May be caused by hypokalaemia, hyperkalaemia or necrosis
| |
| − | *Histologically:
| |
| − | **Swollen
| |
| − | **Hypereosinophilic
| |
| − | **Lost cross striations
