Hormones from the hypothalamus reach the anterior pituitary via the hypophyseal portal system. The anterior pituitary produces seven hormones. These are the growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), beta endorphin, and prolactin.
The hypophyseal portal system is a system of blood vessels in the microcirculation at the base of the brain, connecting the hypothalamus with the anterior pituitary. Its main function is to quickly transport and exchange hormones between the hypothalamus arcuate nucleus and anterior pituitary gland. The capillaries in the portal system are ...

Nov 3, 2023 · To summarize, the hypophyseal portal system consists of the primary and secondary capillary plexuses (beds) in the pituitary gland, plus the intervening portal veins. Hypothalamohypophyseal tract. The hypothalamohypophyseal tract is a bundle of axons that connects the hypothalamic nuclei with the neurohypophysis. Its function is to carry the ...
Once the pituitary matures, the ability of the hypothalamus to communicate with the pars distalis is dependent upon the hypophysial portal system, a vascular link that connects the base of the hypothalamus to the pituitary gland.
In most vertebrates, hypothalamic secretions are delivered to receptors in the pituitary gland through the hypophyseal portal system, a series of fenestrated blood capillaries between the hypothalamus and anterior pituitary gland (adenohypophysis). Teleosts lack this system, instead relying on direct innervation.
