Thyroid-Stimulating Hormone (TSH)
|
|
Thyroid-Stimulating Hormone (TSH) The hormone released from the pituitary that causes the thyroid gland to produce T4 hormone. TSH uses the second messenger cyclic AMP to initiate the synthesis of T4.
RELATED TERMS--------------------------------------
Hormone
A chemical substance formed in the body that is carried in the bloodstream to affect another part of the body; an example is thyroid hormone, produced by the thyroid gland in the neck, which affects growth, temperature regulation, metabolic rate, and other body functions.
Pituitary
The gland from which a number of hormones are released into the bloodstream. These hormones include growth hormone, ACTH, B-lipocortin (the precursor to B-endorphorin), FSH, LH, and TSH.
Thyroid
The gland in the throat that synthesizes thyroid hormones that affect metabolism.
Gland
An organ that releases a chemical. Endocrine glands are ductless and secrete hormones directly into the bloodstream. Exocrine glands secrete externally, either through a tube or duct.

Thyroid Stimulating Hormone (TSH)
A hormone secreted by the anterior pituitary gland, that controls the production and release of the thyroid hormones (T4 and T3). Measurement of the TSH level in the bloodstream is commonly done as a screening tool for hypothyroidism and hyperthyroidism, and as an assessment of the adequacy of therapy in people who are taking thyroid hormone pills as therapy. Typically, high values of TSH are associated with hypothyroidism, and absence of TSH is associated with hyperthyroidism.
Thyroid-Releasing Hormone (TRH)
The hormone released from the hypothalamus. It instructs the pituitary to release TSH.

Triglycerides (TG)
The form of fat found in various lipoproteins in the bloodstream. High levels of triglycerides are usually indicative of high levels of insulin. The ratio of TG/HDL is a powerful indicator of insulin levels and is strongly predictive of future cardiovascular events.
Type 2 Diabetes
A diabetic condition characterized by the overproduction of insulin (hyperinsulinemia), increased AGE production, and decreased longevity.
T3
The active form of T4 synthesized in the peripheral tissue.
T4
The thyroid hormone that is released from the thyroid gland in response to TSH, which generates cyclic AMP.
Trachea
The trachea is a tube which extends from the larynx to the esophagus. It is connected to the trachea at about the area where the larynx is located. It functions as a tube for air to pass through from the external environment to the lungs. It is composed of C-shaped cartilage rings which are embedded in the smooth muscle. The cartilage prevents the trachea from collapsing and closing off the airway.
