The thyroid gland keeps under control how the body uses energy, makes proteins, and keeps control how sensitive the body is to other hormones. Thyroid hormones are produced by these actions. Main hormones of the thyroid system are triiodothyronine and thyroxine (T3 and T4). Hormones are regulated by these, select the speed in which your metabolism is regulated at, and affect the growth and rate of function of the many other delicate systems in the human body. The thyroid gland creates calcitonin, this plays a role in calcium homeostasis. The triiodothyronine (T3) and thyroxine (T4) is combined from iodine and tyrosine. Altered thyroid hormone secretions are common which act virtually on every cell in the human body having diverse actions. Over production of this hormone will have a strong effect on the human body.
Due to the shape of the thyroid cartilage being a shield or a butterfly shape, the thyroid adapted its name from Greece. Commonly known problems of the gland is overactive thyroid problems which is referred to as hyperthyroidism, then there is also the underactive thyroid problems referred to as hypothyroidism.

The lone purpose of the parathyroid gland is to keep under control the calcium in the blood and bones in our body. There is a very tightly controlled range of 9.0 and 10.1, by doing this the Parathyroid will control the amount of calcium in the bones, consequently this will determine how strong and dense the bones are. Even though the Parathyroid gland is sometimes inside the thyroid gland or found next to there is no related function between the two glands.
Calcium in our body is the main individual part that allows normal conduction of electrical currents along our nerves. This is how our nervous system works and how one nerve operates next to the other nerve. The whole brain in the human body works by impulses of calcium into and out of the nerve cells. The importance of calcium in the human body helps muscles to contract being the primary element.
The major function of calcium will help us reason why people may get a tingling feeling in their finger or maybe cramps in the muscles of their hands when the calcium level drops below normal. After a completely successful parathyroid operation a patient may not take their calcium pills for the first few days after the surgery. The patient will experience a sudden drop in important calcium levels and have a feeling of confusion like their brain is not working properly.

The human body’s metabolism is regulated by the thyroid gland, which has no effect on calcium levels while the parathyroid glands regulate the human body’s calcium levels and have no effect on the metabolism.
