  • Parathyroid Hormone - Increase calcium ions [Ca2+], stimulates osteoclasts, increase Ca GIT absorption (opposite effect to calcitonin)
  • Adult Calcium and Phosphate - Daily turnover in human with dietary intake of 1000 mg/day
  • secreted by chief cells

Principal cells cords of cells

Parathyroid Development

Pharyngeal pouches
  • Endoderm - third and fourth pharyngeal pouches, could also have ectoderm and neural crest
    • 3rd Pharyngeal Pouch - inferior parathyroid, initially descends with thymus
    • 4th Pharyngeal Pouch - superior parathyroid
  • Week 6 - diverticulum elongate, hollow then solid, dorsal cell proliferation
  • Fetal parathyroids - respond to calcium levels, fetal calcium levels higher than maternal
