Like other hormones of the anterior pituitary (adenohypophysis), TSH is stimulated by a releasing hormone produced in the hypothalamus. This releasing hormone, TRH (thyrotropin releasing hormone) travels down the pituitary stalk and stimulates the thyrotrope cells there, via the portal circulation of the pituitary.

What are someTropic hormone?
ADH and TSH. are the examples of trophic hormones which produce in small quantity .
Why would TSH have no effect on the metbolic rate of the thyroidectomized rat?
The only effect of TSH (Thyroid Stimulating Hormone) is to stimulate the thyroid gland tissue to produce thyroxine. If there is no longer a thyroid gland to stimulate, the TSH is produced in great abundance, but with no effect.
In Grave's autoimmune disease of the thyroid?
thyroid cells produce class-2 MHC molecules that stimulate autoantibodies that bind to the TSH receptor
What hormone can result in a goiter?
It is a hormone called T4, or thyroxin. What would normally happen is that Thyroid Stimulating Hormone (TSH) from the anterior pituitary would stimulate the thyroid to release T4. When enough T4 is produced, it inhibits TSH, or thyroid stimulating hormone, from being secreted. However if enough T4 is not released to inhibit TSH (probably due to an iodine deficiency), then TSH keeps on secreting, overstimulating the thyroid and causing the swelling known as goiter.
Tsh 9.7 what does that mean?
TSH is thyroid stimulating hormone. 9.7 is the concentration of TSH in your blood.
What does TSH level 3.89 mean?
is a 3.89 tsh level high?
Is a TSH of 1.08 good?
Yes, a TSH of 1.08 is within the normal range.
As thyroxine levels increase in the blood they exert negative feedback on the release of TSH by the pituitary gland. What effect will this have on the release of TSH?
As thyroxine levels increase the amount of TSH produced will decrease. On the other hand, when TSH levels increase the thyroxine levels will decrease. This is what causes the TSH/thyroxine levels to fluctuate.
Is a TSH value of 5.35 considered hyperthyroidism?
Because TSH is a part of the body's negative feedback system which controls the thyroid's output of thyroid hormones, a DECREASE of TSH would indicate hypERthyroidism. An INCREASE of TSH indicates hypOthyroidism.
Does the over production of tsh cause hypothyroidism?
No. An overproduction of TSH would cause hyperthyroidism.
What happens to TSH as thyroxine increase?
tsh goes down as thyroxine goes up.
Is a tsh level of 0.61 overactive or underactive?
is a tsh level of 0.61 overactive or underactive
