Hormones released by hypothalamus :

• Thyrotropin Releasing Hormone (TRH) - This hormone will affect the anterior pituitary which will then affect thyroid gland activity
• Prolactin Releasing Hormone (PRH) and Prolactin Release-Inhibiting Hormone (PIH)
  These two hormones will affect the secretion of prolactin from the anterior pituitary
• Corticotropin Releasing Hormone (CRH) - This hormone affects ACTH release from the anterior pituitary
• Gonadotropin Releasing Hormone (GnRH) - This hormone affects the anterior pituitary which then affects the gonadal release of sex hormones
• Growth Hormone Releasing Hormone (GHRH) and Somatostatin (SS) - These two hormones both affect secretion of growth hormone by the anterior pituitary

The hypothalamus makes two additional hormones:  Oxytocin and antidiuretic hormone i.e. ADH. However the hypothalamus does not secrete these hormones. Instead, the neurons that make the hormones transport the hormones to their axonal terminals. These axonal terminals are located in the posterior pituitary.
