first enter into the hypophyseal portal system
No, because the hypothalamus manufactures the hormones for the posterior pituitary gland and it sends the instructions for the anterior pituitary gland to produce hormones.
It releases hormones that then affects the pituitary.
it is by the hypophyseal portal system, which is a system of blood vessels that connects parts of the hypothalamus to the anterior pituitary gland. The hypothalamus secretes hormones into this portal system and the hormones act on the anterior pituitary to trigger the synthesis/secretion of pituitary hormones.

The hypothalamus is connected to the pituitary gland in two ways. One is via the hypophyseal portal system, which is a system of blood vessels that connects parts of the hypothalamus to the anterior pituitary gland. The hypothalamus secretes hormones into this portal system and the hormones act on the anterior pituitary to trigger the synthesis/secretion of pituitary hormones. The other is a direct anatomical connection between the hypothalamus and the posterior pituitary gland. In fact, the posterior pituitary gland is actually just an extension of the hypothalamus. When we talk about hormones released by the posterior pituitary, we're actually talking about hormones made and released by the hypothalamus. It just so happens that with the naked eye, it looks like the anterior and posterior pituitary are all part of one big pituitary gland. But microscopically, functionally and anatomically, the pituitary gland is just an outgrowth of the hypothalamus.
the hypothalamus
The hypothalamus and pituitary gland are both located in the CNS.The hypothalamus is part of both the central nervous system and the endocrine system because it sends out nervous impulses and manufactures hormones. The hypothalamus' hormones tell the pituitary gland to either secrete or stop secreting its hormones.
Pituitary Gland
These hormones arrived in the posterior pituitary from the storage of hormones made by the hypothalamus of the brain for release as needed in the body.
It is because the hypothalamus of the brain consists of the Releasing Hormones which the pituitary stimulates Thus controls the pituitary.
in the endocrine system the hypothalamus produces hormones that control the pituitary gland.
