The thyroid is a gland located in the front of the neck just above the breast bone. Normally it is small and cannot be seen when someone looks at the neck.
The thyroid gland makes a hormone called "thyroid hormone" that travels through the blood stream to all of the body's cells. There are actually two thyroid hormones in the blood stream:
Thyroid hormone determines how active the body's cells are. The thyroid gland knows how to make thyroid hormone but it doesn't know how much hormone to make. Instead it relies for this information on a signal from another gland at the base of the brain called the "pituitary gland."
One of the jobs of the pituitary gland is to constantly test the blood stream to see if there is enough thyroid hormone present. If not, then the pituitary sends out its own hormone called "thyroid stimulating hormone" or "TSH", which stimulates the thyroid gland to make more thyroid hormone.
