The neurosecretory cells (neurons) of hypothalamus secrete hormones called neurohormones (releasing factors) which are summarised below.

  1. Adrenocorticotropic releasing hormone (ARH): It stimulates the anterior lobe of the pituitary gland to secrete adrenocorticotropic hormone (ACTH).
  2. Thyrotropin releasing hormone (TRH) : It stimulates the anterior lobe of the pituitary gland to secrete thyroid stimulating hormone (TSH) or thyrotropin.
  3. Somatotropin Releasing hormone (SRH) : It stimulates the anterior lobe of the pituitary gland to release growth hormone (GH) or somatotropin.
  4. Growth inhibiting hormone (GIH): This hormone is also called somatostatin (SS). It inhibits the secretion of growth hormone from the anterior lobe of the pituitary gland.
  5. Gonadotropin releasing hormone (GnRH) : It
    stimulates the anterior lobe of the pituitary gland to secrete two gonadotropic hormones : follicle stimulating hormone (FSH) and luetinising hormone (LH).
  6. Prolactin releasing hormone (PRH) : It stimulates j the anterior lobe of the pituitary gland to secrete prolactin.
  7. Prolactin inhibiting hormone (PIH) : It inhibits
    the secretion of prolactin from the anterior lobe of pituitary gland.
  8. Melanocyte releasing stimulating hormone (MRH) : It stimulates the intermediate lobe of the pituitary gland to secrete its melanocyte stimulating hormone (MSH).
  9. Melanocyte inhibiting hormone (MIH): It inhibits the secretion of melanocyte stimulating hormone from the intermediate lobe of the pituitary gland.
