Full Thyroid Gland Description
[Continued from above] . . . world, iodine is so scarce that most of the population has goiters. The parathyroid glands are four small oval bodies located on either side of and on the dorsal aspect of the thyroid gland. These glands control the level of calcium in the blood. The thyroid gland secretes hormones that regulate energy, and emotional balance may rely upon its normal functioning. When the rate of production is excessive, the results can be weight loss, nervousness, or even emotional disturbances. If the rate of production is excessively low, a slowing of bodily functions may result. The parathyroid glands, located behind the thyroid, control the blood-calcium level. Calcium is important, not only for bones and teeth, but also for nerve functioning, muscle contractions, blood clotting and glandular secretion. If we don't have enough calcium for these functions, the body will take it from the bones, causing them to easily fracture. It may also cause twitching, spasms, convulsions and even death. Too much calcium may cause a weakening of muscle tone and kidney stones.
