Thyroid-Releasing Hormone (TRH)
|
|
Thyroid-Releasing Hormone (TRH) The hormone released from the hypothalamus. It instructs the pituitary to release TSH.
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.
Hypothalamus
The portion of the brain's limbic system that integrates incoming information, and either increases or decreases the release of certain hormones that instruct the pituitary gland to release hormones.
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.
TSH
Thyroid-stimulating hormone. A pituitary hormone that stimulates thyroid hormone production.

Thyro-block

Thyroid
The gland in the throat that synthesizes thyroid hormones that affect metabolism.
Thyroid scan
Uses a radioactive substance to create an image of the thyroid as it is functioning.
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-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.

PREVIOUS AND NEXT TERMS--------------------------------------
Thymine
A nitrogenous base, one member of the base pair AT (adenine-thymine).
Telomer

Testosterone
The hormone that promotes the building of muscle mass in males and libido in both sexes.
Thymus
