German: Thyreotropin
Thyrotropin is a peptide-hormone that is secreted by the anterior pituitary lobe. It stimulates formation of thyroid hormones in the thyroid gland. Conversely, in the context of a feedback control TSH secretion in the pituitary is inhibited by thyroid hormones (thyrotropic feedback control).
Physiology
The following factors influence secretion of TSH:Stimulating factors
- TRH
- Neurotensin
- Vasopressin (ADH, presumably)
Inhibiting factors
- Thyroxine (T4) and Triiodothyronine (T3)
- Somatostatin
- Dopamin
- TSH
- Thyrostimulin (TSH 2)
- Zytokines (presumably)
