Question

question 16
which cells synthesize and secrete pth?
follicular cells
oxyphil cells
parafollicular cells
chief cells

Explanation:

Parathyroid hormone (PTH) is synthesized and secreted by chief cells in the parathyroid glands. Follicular cells are related to thyroid hormones (e.g., thyroxine), oxyphil cells' function is less clear (possibly related to calcium - phosphate metabolism but not PTH production), and parafollicular cells (also known as C - cells) secrete calcitonin.

Answer:

Chief cells
