*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
