The C Cells of the Thyroid Gland Produce

Question

The C cells of the thyroid gland produce
A) thyroxine.
B) TSH.
C) calcitonin.
D) PTH.
E) triiodothyronine.

Accepted Answer

The C cells of the thyroid gland produce calcitonin, which helps regulate calcium levels in the body by inhibiting osteoclast activity (cells that break down bone) and increasing calcium excretion by the kidneys. The A and B cells of the thyroid gland produce thyroxine and triiodothyronine, respectively, while PTH (parathyroid hormone) is produced by the parathyroid glands.
