pituitary hormones

Hormones of the anterior lobe of the pituitary gland, including the growth hormones (somatotropin 1, lactogenic hormone, prolactin, galactin, mam-motropin) and pituitary tropins (go-nadotropins, thyrotropic hormone, and ACTH). Whether or not a true diabetogenic pituitary hormone exists is a question. The melanocyte-stimulating hormone is secreted by the middle lobe of the pituitary gland, and vasopressin and oxytocin are secreted by the posterior lobe of the pituitary gland.
