10 Warnings Signs Of STROKE A Week BEFORE It Happens

Metabolic rate and hormone balance -

A peroxidase enzyme then attaches the iodine to the tyrosine amino acid found in thyroglobulin. T 3 has three iodine ions attached, while T 4 has four iodine ions attached. T 3 and T 4 are then released into the bloodstream, with T 4 being released in much greater amounts than T 3.

As T 3 is more active than T 4 and is responsible for most of the effects of thyroid hormones, tissues of the body convert T 4 to T 3 by the removal of an iodine ion.

Most of the released T 3 and T 4 becomes attached to transport proteins in the bloodstream and is unable to cross the plasma membrane of cells. These protein-bound molecules are only released when blood levels of the unattached hormone begin to decline. Increased T 3 and T 4 levels in the blood inhibit the release of TSH, which results in lower T 3 and T 4 release from the thyroid.

The follicular cells of the thyroid require iodides anions of iodine in order to synthesize T 3 and T 4. Iodides obtained from the diet are actively transported into follicle cells resulting in a concentration that is approximately 30 times higher than in blood.

The typical diet in North America provides more iodine than required due to the addition of iodide to table salt. Inadequate iodine intake, which occurs in many developing countries, results in an inability to synthesize T 3 and T 4 hormones.

The thyroid gland enlarges in a condition called goiter , which is caused by overproduction of TSH without the formation of thyroid hormone. Thyroglobulin is contained in a fluid called colloid, and TSH stimulation results in higher levels of colloid accumulation in the thyroid. In the absence of iodine, this is not converted to thyroid hormone, and colloid begins to accumulate more and more in the thyroid gland, leading to goiter.

Disorders can arise from both the underproduction and overproduction of thyroid hormones. Hypothyroidism , underproduction of the thyroid hormones, can cause a low metabolic rate leading to weight gain, sensitivity to cold, and reduced mental activity, among other symptoms.

In children, hypothyroidism can cause cretinism, which can lead to mental retardation and growth defects. Hyperthyroidism , the overproduction of thyroid hormones, can lead to an increased metabolic rate and its effects: weight loss, excess heat production, sweating, and an increased heart rate.

Insulin is produced by the pancreas in response to rising blood glucose levels and allows cells to utilize blood glucose and store excess glucose for later use. Diabetes mellitus is caused by reduced insulin activity and causes high blood glucose levels, or hyperglycemia.

Glucagon is released by the pancreas in response to low blood glucose levels and stimulates the breakdown of glycogen into glucose, which can be used by the body. The anterior pituitary produces thyroid stimulating hormone TSH , which controls the release of T 3 and T 4 from the thyroid gland.

Iodine is necessary in the production of thyroid hormone, and the lack of iodine can lead to a condition called goiter. Improve this page Learn More. Skip to main content.
