First, determine how much the temperature in the oven is off from the control setting. To do this, put an oven thermometer on a center rack inside the oven and turn the oven on for about 20 minutes, with the thermostat set at any range between 300 degrees and 400 degrees Farenheit.n oven that won't heat or heats unevenly most likely involves a faulty control, thermostat, or timer. Don't worry because most of these problems can be handled yourself at minimal cost. When the oven setting control malfunctions, the oven won't heat. Here's how to repair an oven setting control:
The parathyroid glands, located on the dorsal aspect of the thyroid gland, secrete parathyroid hormone (PTH), which causes an increase in blood calcium levels by targeting bone, the intestine, and the kidneys. PTH is the antagonist of calcitonin.he parathyroid glands, located on the dorsal aspect of the thyroid gland, secrete parathyroid hormone (PTH), which causes an increase in blood calcium levels by targeting bone, the intestine, and the kidneys. PTH is the antagonist of calcitonin.
When the calcium level in the blood is too low, the cells of the parathyroids sense it and make more parathyroid hormone. Once the parathyroid hormone is released into the blood, it circulates to act in a number of places to increase the amount of calcium in the blood (like removing calcium from bones).earn how parathyroid glands work by making parathyroid hormone to control blood and bone calcium. This page of Parathyroid.com discusses the normal function of parathyroid glands, how parathyroid glands monitor and control blood calcium and what it means to have high blood calcium.
