Where are the parathyroid glands located?

In the throat, on the thyroid.

What type of hormone does the gland produce?• PTH(parathyroid hormone)

What affect do these hormones have on the human body?

•Regulates calcium levelsNot enough calcium, more PTH produced and released

Too much calcium, PTH stops being produced

Why are these hormones important to the maintenance of homeostasis?

• Controls amount of calcium that is in blood, therefore controls bone strength and density

Feedback Mechanisms and Antagonistic Hormones

• When the calcium concentration falls below the recommended level PTH raises the calcium concentration by decreasing bone deposition and increasing the calcium uptake in the intestine and the kidneys.

Releasing hormones and glands and release-inhibiting hormones and glands

• PTH is produced and released when calcium levels get low (below 9.0)

What happens if the gland does not function properly?

• If one (or more) of the four parathyroid glands grows into a tumor, it behaves inappropriately by constantly making excess parathyroid hormone, even when unnecessary.

What can be done to fix the problems the not working gland causes?

• The MIRP Procedure• The standard Parathyroid Operation• Minimally Invasive Parathyroid Operation

Diseases

•Hyperparathyroidism- Hyperparathyroidism Video•Hypoparathyroidism- very rare, too little calcium, occurs when all 4 parathyroid glands stop working
