Pituitary hormones

Pituitary hormones are produced by parts of pituitary gland.

Posterior pituitary (neurohypophysis)
The hormones secreted by the posterior pituitary are
 * Oxytocin comes from the paraventricular nucleus in the Hypothalamus
 * Antidiuretic hormone (ADH - also known as vasopressin and AVP, arginine vasopressin), comes from the supraoptic nucleus in the Hypothalamus

Anterior pituitary (Adenohypophysis)
The anterior pituitary hormones, and the hypothalamic hormones that modulate their release are listed below, along with the associated cell types.

The hypothalamic hormones travel to the anterior lobe by way of a special capillary system, called the hypothalamic-hypophyseal portal system.

There is also an interaction between the hormones from the hypothalamus, i.e. TRH induces the release of prolactin.

The control of hormones from the pituitary is in a negative feedback loop. Their release is inhibited by increasing levels of hormones from the target gland on which they act.
