Document Summary

The blood is drained via venous drainage to go else where in the body. One half is connected to hypothalamus (through median eminence inside the stem) Goes to the posterior pituitary; this part is connected to the hypothalamus. The other part is not, this other side has the hypophyseal portal vein. Hypothalamus released hormones to this vein, which travels to anterior pituitary. Anterior pituitary releases a lot of hormones. Acth: goes to adrenal cortex for the release of cortisol. Tsh: binds to thyroids and increases metabolism. For posterior, oxytocin is made in hypothalamus and released into posterior, form there it is released again into blood stream. For anterior, hormones come into vein, hormones bind to receptors, leads to release of hormones (intermediate processes) Hypothalamus pituitary adrenal cortex cortisol release. Negative feedback: cortisol stops its own release. Energy being spent will be replenished by cortisol.
