The hypothalamus sends the TRH hormone via some capillaries. Now, these are very special capillaries, yes they connect to the circulation, as capillaries do. However, these capillaries are different in that they act as a portal. In fact, they have a name for them too, called the hypothalamo-pituitary portal vessels. Basically how they work is, blood coming from the heart first integrates into the hypothalamus, and upon the exocytosis type of release from the nuclei within the hypothalamus that contain the hormones (talking about in this way the nuclui that produce the homones release those hormones directly into capillaries via a similar manner as how neurotransmitters are released into a synapse). Once the hormones are released into the capillaries of the hypothalamus-pituitary vessels, they travel down and into the anterior pituitary. Where they are actively transported into the cells of the anterior pituitary (notice nothing about the posterior pituitary, because that functions in a different manner).
What else can I help you with?
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.
What connects the hypothalamus to the posterior pituitary?
By using the gravilite projectiles aiming stimulation towards your reluctent postual clavicle, streaming straight to your phalanges causing major damage, or as the sloppy male likes to call it "you'll be like a babe on he rags"
What hormones are secreted by the hypothalamus?
There are 7 different hormones released from the hypothalamus. They all are regulatory hormones that act on the anterior pituitary with the exception of prolactin inhibitory hormone. Most of them have a positive influence on the anterior pituitary, but there is also a negative influence on the growth hormone release.The 7 different hormones released are:GHRH (Growth hormone releasing hormone) - counteracted by another hormone released from the hypothalamus called Somatostatin, which blocks hormone release. (+)Growth hormone release inhibitory hormone - Somatostatin (-)CRH (Corticotropin releasing hormone) - acts on the adrenal glands to stimulate corticoid metabolism (+)TRH (Thyrotropin releasing hormone) - act on target cells within the pituitary gland (+)Gonadotropin releasing hormone (GnRH) - acts on target cells within the anterior pituitary to stimulate thyroid hormone production. (+)Prolactin inhibitory hormone - Dopamine(-)PRH (Prolactin releasing hormone) (+)
What hormones do the hypothalamus make?

How does TRH travel from hypothalamus to the pituitary gland?
by the Hypothalamic-pituitary portal system
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.
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 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 releases TSH?
TSH is inhibited by feedback inhibition exerted by the thyroid hormones on the anterior pituitary and hypothalamus and by GHIH.
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.
How does the body know when to produce more thyroxine?
There is a part of the brain called the hypothalamus which is next to the pituitary. When you have not enough Thyroxine (T4) your hypothalamus makes TRH which tells the pituitary to make Thyroid stimulating hormone (TSH). TSH as in the name stimulates the thyroid gland in the neck to make more Thyroxine.
What does TSH stimulate?
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 is the role of the hypothalamus in the production of thyroxine and TSH?
The hypothalamus produces TSH Releasing Hormone (TRH) that signals the pituitary to tell the thyroid gland to produce more or less of T3 and T4 by either increasing or decreasing the release of a hormone called thyroid stimulating hormone (TSH).
What two hormones from the hypothalamus stimulate the release of hormones from the anterior pituitary?
growth hormone-releasing hormone (GHRH)
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 controls thyroxine?
Is a hormone secreted bx thyroid gland important in maintaing calcium and phosphate balance of the body,normal development of neurons,maintaining metabolic rate,important in growth of infants.
