What is TRH's role in the endocrine system?
Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus and stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland. TSH then acts on the thyroid gland to stimulate the production and release of thyroid hormones, which regulate metabolism and energy balance in the body.
What is TRH?
TRH stands for thyrotropin-releasing hormone. It is a hormone produced by the hypothalamus that stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland, which in turn regulates the release of thyroid hormones from the thyroid gland.
How would the feedback mechanism function to restore homeostasis after low tsh levels?
When TSH (thyroid-stimulating hormone) levels are low, the hypothalamus detects this decrease and responds by releasing more thyrotropin-releasing hormone (TRH). Increased TRH stimulates the pituitary gland to produce and secrete more TSH. Elevated TSH levels then promote the thyroid gland to produce more thyroid hormones (T3 and T4), which helps restore homeostasis by regulating metabolism and other bodily functions. This feedback loop continues until TSH levels return to a normal range.
Which hormone does hypothalamus gland secrete?
The hypothalamus gland secretes releasing hormones, such as Gonadotropin-releasing hormone (GnRH), Corticotropin-releasing hormone (CRH), and Growth hormone-releasing hormone (GHRH), that stimulate the release of hormones from the pituitary gland.
What are some examples of a positive feedback loop and a negative feedback loop?
The most common by far is negative feedback, pretty much every hormone works through negative feedback. Take for example tiroxine: low levels of tiroxine induce production of TRH and TSH which in time increase production of tiroxine, and when the levels of tiroxine are high, it lowers the production of TRH and TSH, lowering production of tiroxine as well. Another example would be insulin: when blood sugar levels rise, the pancreas produces more insulin, and once it takes effect and blood sugar levels lower, the pancras stops the increased production. Positive feedback on the other hand is more rare, an example would be childbirthing, when the baby stretches the cervix, it induces production of oxytocin in the pituitary gland, which causes the contractions of the uterus, pushing the baby out and stretching the cervix even more, making the pituitary gland produce even more oxytocin
What hormone does tsh release?
TRH
What is TRH's role in the endocrine system?
Thyrotropin-releasing hormone (TRH) is produced by the hypothalamus and stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland. TSH then acts on the thyroid gland to stimulate the production and release of thyroid hormones, which regulate metabolism and energy balance in the body.
Does increased thyroid hormone production increase or decrease TRH production?
Thyroid releasing hormone (TRH) is released when thyroid hormones are low. Increased thyroid hormone production would serve to inhibit/decrease TRH release.
What is TRH?
TRH stands for thyrotropin-releasing hormone. It is a hormone produced by the hypothalamus that stimulates the release of thyroid-stimulating hormone (TSH) from the pituitary gland, which in turn regulates the release of thyroid hormones from the thyroid gland.
What two hormones from the hypothalamus stimulate the release of hormones from the anterior pituitary?
growth hormone-releasing hormone (GHRH)
What releases TSH?
TSH is inhibited by feedback inhibition exerted by the thyroid hormones on the anterior pituitary and hypothalamus and by GHIH.
What are the normal blood values for TRH?
10-20

How does the TRH travel from the hypothalamus to the pituaitary gland?
The hypothalamus sends releasing hormones to the pituitary gland down through a salk of tissue called the infundibulum. It tells it which hormones to make and when to make them.

A hormone that influences an endocrine gland other than its source?
An example of a hormone that influences an endocrine gland other than its source is thyrotropin-releasing hormone (TRH). TRH is released by the hypothalamus and acts on the anterior pituitary gland to stimulate the release of thyroid-stimulating hormone (TSH), which in turn acts on the thyroid gland to regulate thyroid hormone production.
