Understanding Skeletal Issues: Osteoporosis & Rigor Mortis

Two distinct skeletal phenomena:

  • Osteoporosis: A living bone disease where mineral loss (calcium, phosphate) causes porous, brittle bones prone to fracture.
  • Rigor Mortis: Postmortem stiffening of muscles due to ATP depletion, causing joints to lock—unrelated to bone health.

Osteoporosis is a treatable metabolic condition; rigor mortis is a natural after-death process.
