Insulinlike growth factors (IGFs), etc.) LH Glycoprotein  Structurally similar to FSH Anterior pituitary Testes/ovaries  Stimulates ovaries & testes  & TSH Prolactin (PRL) Protein  Anterior pituitary Mammary glands  Stimulates milk production/secretion   Varied effects from species to species TSH Glycoprotein  Stimulates production of3T Anterior pituitary Thyroid  Stimulates thyroid gland  & T 4  Structurally similar to LH & FSH MSH Peptide  Anterior pituitary Melanocytes  Regulates activity of pigment-containing cells in skin  ADH (Vassopressin) Peptide  N/a; regulated by water/saltPosterior pituitary Collecting ducts in kidneys  Prevent dehydration  Hyposecretion : Diabetes balance  Reabsorb water from urine insipidus Oxytocin Peptide  Posterior pituitary Mammary glands, uterine  Stimulates contraction of uterus & mammary gland cells  muscles  Mammary glands secrete milk Estrogens Steroid Ovaries  Regulated by FSH & LH  Stimulate uterine lining
