Where is thyrotropin releasing hormone released from?
Also, what causes the release of thyrotropin releasing hormone?
Thyrotropin-releasing hormone (TRH) from the hypothalamus stimulates the pituitary to release TSH. TRH = thyrotropin-releasing hormone; TSH = thyroid-stimulating hormone. Binding of TSH to receptors on the thyroid gland leads to the release of thyroid hormones—primarily T4 and to a lesser extent T3.
Furthermore, what gland releases TSH? The hypothalamus, in the base of the brain, produces thyrotropin-releasing hormone (TRH). TRH stimulates the anterior pituitary gland to produce TSH.
Accordingly, where is prolactin releasing hormone produced?
In humans, prolactin is produced both in the front portion of the pituitary gland (anterior pituitary gland) and in a range of sites elsewhere in the body. Lactotroph cells in the pituitary gland produce prolactin, where it is stored and then released into the bloodstream.
What organ is affected by TSH?
The anterior pituitary hormones enter the systemic circulation and bind to their receptors on other target organs. In the case of TSH, the target organ is the thyroid gland. Clearly, robust control systems must be in place to prevent over or under-secretion of hypothalamic and anterior pituitary hormones.
