The thyroid gland consists of:

a. follicle cells that secrete calcitonin.

b. spherical thyroid follicles that contain iodine-containing colloid.

c. parafollicular cells that produce thyroid hormones.

d. spherical thyroid follicles that surround parathyroid hormone–secreting cells.

Hey, everyone. Let's take a look at this question together the follicular cells of the thyroid gland secrete thyroid hormone. While the para follicular cells secrete, what is it? Answer choice. A parathyroid hormone, answer choice. B calcitonin. Answer choice. C thyroid stimulating hormone or answer choice. D thyrotropin releasing hormone or trh. Let's work this problem out together to try to figure out which of the following answer choices is what is secreted by the pair of follicular cells. So in order to solve this question, we have to recall what we have learned about the para follicular cells and what they are responsible for secreting. And we can recall that the para follicular cells also known as the C cells are scattered throughout the thyroid gland. And the para follicular cells are responsible for the synthesis storage and secretion of calcitonin. Which means that answer choice. B calcitonin is the correct answer. And all other answer choices are incorrect. Since calcitonin is secreted by the pair follicular cells, I hope you found this video to be helpful. Thank you and goodbye.
