Parathyroid Gland Histology

Basic Components
  • Parathyroid Gland Capsule:
    • Each parathyroid gland is invested with a fibrous capsule that is continuous with the thyroid capsule. Thin extensions of the capsule enter the gland itself and divide each gland into small lobules.
  • Parathyroid Chief Cells
    • These are the primary functional cells of the parathyroid gland. These cells synthesize and regulate secretion of PTH. Note: These cells should not be confused with gastric chief cells.
  • Oxyntic Cells
    • These cells are also present in the parathyroid gland but do not have a significant endocrinological purpose.
