PTH
parathyroid hormone. it causes calcium to be released into the blood.
Calcitonin
the parathyroid hormone (PTH) is released by the parathyroid gland (located behind the thyroid gland). A decrease in blood calcium causes the parathyroid gland to secrete PTH which causes the bones to release more calcium to raise blood calcium and also causes the kidneys to decrease the amount of calcium lost in urine
calcitonin and PTH
The parathyroid glands (4 of them) secrete parathyroid hormone to increase blood calcium. When the parathyroid glands detect low blood calcium levels, they secrete more parathyroid hormone, which causes the bones to release calcium to the bloodstream, thereby increasing blood calcium levels.
PTH activates vitamin D in the body, which absorbs calcium and phosphate from foods. It works on the intestine to increase the absorption of calcium. It causes the bones to release more calcium, and causes the kidneys to reabsorb more calcium. This all helps to increase calcium levels.
Parathyroid hormone (PTH) raises calcium levels in the blood when it's sensed that calcium levels are a bit lower than they ought to be. 99% of your body's calcium in the bones, so it stands to reason that PTH acts on bone to have it release calcium into the bloodstream. Indeed, this is exactly how the hormone works. A detailed mechanism for how this occurs is given in: http://en.wikipedia.org/wiki/Parathyroid_hormone Cheers.
The Pancreas makes insulin which causes cells to take up glucose from the blood stream and store it as glycogen which causes cells to release their glucose into the bloodstream.
The function of the parathyroid glands is to secrete parathyroid hormone, which causes the release of the calcium present in bone to extracellular fluid (ECF). The ECF is the fluid found outside cells in all body tissues. PTH does this by activating the production of osteoblasts, special cells of the body involved in the production of bone and slowing down osteoclasts, other specialized cells involved in the removal of bone.

The hormone is called as calcitonin. This hormone is secreted by the parathyroid glands.
Nuerotransmitters are released when calcium reacts and causes a chemical reaction within the synapse.
