Hypothalamic and Pituitary Hormones

1. Hypothalamic Hormones

1.1. action: on the pituitary

1.1.1. Hypothalamic hormones are releasing hormones (-RH)

1.1.1.1. GRHR

1.1.1.1.1. Liver, bone, muscle, kidney, among others (Insulin-like growth factor-1 (IGF-1))

1.1.1.5.1. Breast

2. Pituitary Hormones

2.1. action: target tissues (thyroid, ovaries, testies, adrenal cortex)
