The negative feedback system between the pituitary gland and the thyroid.
This happens due to what is called as negative feed back mechanism. Increased blood level of thyroid gland secretions lowers down the thyroid stimulating hormone (TSH) level and vise verse.
The action of other hormones
Thyroid hormone.
by excircsing
Thyroid stimulating hormone (TSH) stimulates the secretion of the hormones thyroxine (T4) and triiodothyronine (T3).
All the hormones from posterior Pitutory.They are FSH,LH,TSH,GH,Prolactin and AcTH.
ADH and TSH. are the examples of trophic hormones which produce in small quantity .
Thyroid secretion hormone is secreted by the thyrotrope cells in d anterior pituitary gland
The hormone that regulates the synthesis and secretion of T3 (Triiodothyronine) and T4 (Thyroxine) by the thyroid gland is thyroid stimulating hormone (TSH) that is produced and secreted by the anterior pituitary gland, also known as the adenohypophysis.
Increase in thyroid hormone will lower TSH production, because there is a feedback loop between TSH that stimulates the production of thyroid hormone and the hormone that then will then regulate the stimulation of TSH so that thyroid hormone is not over produced.
TSH is thyroid stimulating hormone. 9.7 is the concentration of TSH in your blood.
TSH is the thyrotropic hormone or thyroid stimulating hormone which is involved in regulating the growth and activity of the thyroid gland.
High levels of TSH initially increases the level of thyroid hormone (TH). When the TH levels get high, the feedback mechanism starts to work: The excess amount of TH in the blood signals the pituitary gland to decrease secretion of TSH, which decreases the amount of TSH that is secreted by the pituitary gland, and maintains homeostatis.
