Parathyroid Glands

• Parathyroid Glands

  Produces parathormone (PTH)
• Parathyroid Glands

  PTH regulates calcium and phosphorous balance.
• Parathyroid Glands

  PTH elevate calcium levels by withdrawal of calcium from the bones (bone resorption).
• Parathyroid Glands

  The relationship of PTH and calcium is direct proportion.

  • Hypersecretion of PTH: Hypercalcemia
  • Hyposecretion of PTH: Hypocalcemia
• Parathyroid Glands

  The relationship of PTH and phosphorus is inverse.

  • Hypersecretion of PTH: Hypophosphatemia
  • Hyposecretion of PTH: Hyperphosphatemia
