Hypothalamic–pituitary hormone

Although the organs in which they are produced are relatively small, the effects of these hormones cascade throughout the body.

[2] In posterior pituitary we have hormones that control absorption of water and oxytocin.

Anterior pituitary is an amalgam of hormone producing glandular cells.

There are conditions related to the limbic system which regulate the hormone release.

Anterior pituitary produces prolactin, GH, TSH, ACTH, FSH, LH.
