Answer:

b. Calcitonin
c. PTH
d. PTH
e. PTH
f. PTH
g. Calcitonin
Explanation:
Calcitonin is a short peptidic hormone secreted by the parafollicular cells of the thyroid gland. Conversely to the parathyroid hormone (PTH), calcitonin reduces the calcium level in the blood. If the calcium concentration in blood decreases, the concentration of calcitonin secreted decreases too. On the other hand, the PTH peptide hormone is an important hormone secreted by the parathyroid glands that affect bones and tissues. PTH stimulates the proliferation and activity of the osteoclast (specialized cells that play a crucial role in bone resorption) in order to increase calcium levels in the blood. PTH stimulates the expression of the receptor activator of nuclear factor-kappa-Β ligand (RANKL) protein, thereby activating osteoclast differentiation and inhibiting osteoclast apoptosis.
