The parathyroid glands are responsible for monitoring the calcium level in the blood. When the calcium level is too low, the parathyroids produce parathyroid hormone (PTH) to increase the calcium level in our blood.

Which hormone stimulates osteoclasts in the raising of calcium levels in the blood?
If you are looking for the one hormone that does this, then the answer is parathyroid hormone (PTH), produced in the parathyroid glands.A more technical description is given below:Three hormones act in the body to increase blood calcium levels to normal. These hormones are 1,25-Dihydroxycholecalciferol, parathyroid hormone (PTH), and calcitonin that originate respectively from the liver and kidneys, parathyroid glands, and thyroid glands. The first, 1,25-Dihydroxycholecalciferol (active vitamin D3), serves to increase calcium absorption from the intestine. The second, PTH, dissolves bone into the blood. The third, calcitonin, prevents the bone-derived calcium from being resorbed ("reabsorbed") into the bone from which it came via PTH. To summarize, these three hormones act in concert to raise calcium levels via external and internal routes.References: Ganong's Review of Medical Physiology, 23eKim E. Barrett, et. al.

What hormones released by parathyroid gland?
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.
What is secreted in response to hypoxia and produces a negative feedback loop that raises the oxygen concentration of the blood?
erythropoietin
What organ releases hormones which regulate blood glucose levels?
The so-called "Isles of Langerhans" in the pancreas produce the hormone, 'Insulin', which lowers high sugar levels in the bloodstream."Glucagon (GLOO-kuh-gone) is a peptide hormone also produced in the pancreas that raises low sugar levels in the bloodstream.
What pancreatic hormones maintained blood glucose levels?
The pancreas secretes 2 hormones that affect the blood glucose level, they are insulin and glucagon. Glucagon is the hormone that raises blood glucose level. It works by changing glycogen into glucose through a process known as glycogenolysis.
A hormone that raises the blood calcium level?
Parathyroid hormone also 1,25-OH vitamin D.

What is the functions of the thyroid and parathyroid glands in relation to bone?
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.
What two endocrine glands have antagonistic functions?
Thyroid and Parathyroid Glands are Antagonistic. -Thyroid gland produces Calcitonin, which lowers blood calcium levels. -Parathyroid gland produces Parathyroid Hormone (PTH), which raises blood calcium levels. There are very many "antagonistic" hormones that are produced by endocrine glands.
Which hormone directly stimulates growth of muscle tissue leading to increased muscle mass epinephrine thyroid hormone testosterone parathyroid hormone calcitonin?
Testosterone- it raises the rate of protein synthesis causing growth
What is the difference between glucose glycogen and glucagon?
Glucose a monosaccaride otherwise known as sugarused for energyGlycogen is secreted by the pancreas to stimulate an increase in blood sugar levelGlucagon, a hormone secreted by the pancreas, raises blood glucose levels
Hyperparathyroidism?
DefinitionHyperparathyroidism is excessive production of parathyroid hormone (PTH) by the parathyroid glands.See also:Primary hyperparathyroidismSecondary hyperparathyroidismCauses, incidence, and risk factorsThe parathyroid glands are located in the neck, near or attached to the back side of the thyroid gland. They produce parathyroid hormone, which controls calcium, phosphorus, and vitamin D levels within the blood and bone.When calcium levels are too low, the body responds by increasing production of parathyroid hormone. This increase in parathyroid hormone causes more calcium to be taken from the bone and more calcium to be reabsorbed by the intestines and kidney. When the calcium level returns to normal, parathyroid hormone production slows down.There are two main types of hyperparathyroidism.Primary hyperparathyroidism is caused by enlargement of one or more of the parathyroid glands. This leads to too much parathyroid hormone, which raises the level of calcium in the blood. The term "hyperparathyroidism" generally refers to primary hyperparathyroidism.Secondary hyperparathyroidism is when the body produces extra parathyroid hormone because the calcium levels are too low. This is seen when vitamin D levels are low or when calcium is not absorbed from the intestines. Correcting the calcium level and the underlying problem will bring the parathyroid levels in the normal range.If the parathyroid glands continue to produce too much parathyroid hormone even though the calcium level is back to normal, the condition is called "tertiary hyperthyroidism." It occurs especially in patients with kidney problems.SymptomsBack painBlurred vision(because of cataracts)Bone pain or tendernessDecreased heightDepressionFatigueFractures of long bonesIncreased urine outputIncreased thirstItchy skinJoint painLoss of appetiteNauseaMuscle weakness and painPersonality changesStupor and possibly comaUpper abdominal painSigns and testsBlood tests will be done to check for increased levels of parathyroid hormone (PTH), calcium, and alkaline phosphatase, and lower levels of phosphorus. A 24-hour urine collection test can help determine how much calcium is being removed from the body.Bone x-rays and bone mineral density test can help detect bone loss, fractures, or bone softening.X-rays, ultrasound, or CT scans of the kidneys or urinary tract may show calcium deposits or a blockage.TreatmentTreatment depends upon the severity and cause of the condition. If you have mildly increased calcium levels due to primary hyperparathyroidism and no symptoms, you may just need regular check ups with your doctor.If symptoms are present or your calcium level is very high, surgery may be needed to remove the parathyroid gland that is overproducing the hormone.Treatment of secondary hyperparathyroidism depends on the underlying cause.For specific treatment information see:Primary hyperparathyroidismSecondardy hyperparathyroidismExpectations (prognosis)The outlook depends on the specific type of hyperparathyroidism.ComplicationsComplications may include:Increased risk of fracturesUrinary tract infection due to kidney stones and blockagePeptic ulcer diseasePancreatitisPseudogoutSurgery for hyperparathyroidism may lead to low blood calcium levels, which causes tingling and muscle twitching. This requires immediate treatment.Calling your health care providerCall for an appointment with your health care provider if you have symptoms of hyperparathyroidism.PreventionGetting the proper amount of calcium in your diet or through supplements may reduce your risk of secondary hyperparathyroidism.ReferencesWysolmerski JJ.

What is secreted in response to hypoxia?
Erythropoietin is secreted in response to hypoxia. It produces a negative feedback loop that raises the oxygen concentration of the blood. Also called EPO, erythropoietin, is a glycoprotein hormone that controls red blood cell production.
What is glucogon?
Glucagon is a hormone, secreted by the Islets of Langerhans by Alpha Cell in Pancreas, that raises blood glucose levels. Its effect is opposite that of insulin, which lowers blood glucose levels
What hormone reduces blood glucose levels and what hormone raises blood glucose levels?
Glucagon is the hormone that raises blood glucose levels.
What is the function of vasopressin in the human body?
Vasopressin( Anti-diuretic hormone) is a naturally occurring hormone in the body that is secreted by the posterior lobe of the pituitary gland. It constricts blood vessels, raises blood pressure, stimulates water reabsorption, and reduces excretion of urine.
