Posterior Pituitary Hypothalamus Oxytocin and ADH Anterior Pituitary Growth Hormone (GH) Thyroid Stimulating Hormone (TSH) Adrenocorticotropic Hormone (ACTH) Follicle Stimulating Hormone (FSH) Luteinizing Hormone (LH) Prolactin (PRL) Hormone Origin Mechanism Target Tissue Growth Hormone (GH) Anterior Pituitary Stimulated by GHRH release Liver, Muscle, Bone, Cartilage, and Other Tissues Thyroid-Stimulating Hormone (TSH) Anterior Pituitary Stimulated by TRH Thyroid Gland Adrenocorticotropic Hormone (ACTH) Anterior Pituitary Stimulated by CRH Adrenal Cortex Follicle-Stimulating Hormone (FSH) Anterior Pituitary Stimulated by GnRH Ovaries and Testes Luteinizing Hormone (LH) Anterior Pituitary Stimulated by GnRH Ovaries and Testes Prolactin Anterior Pituitary Stimulated by decreased PIH Breast Secretory Tissue Oxytocin Posterior Pituitary Stimulated by impulses from hypothalamic neurons in response to cervical/uterine stretching and suckling of breast Uterus Antidiuretic Hormone (ADH) Posterior Pituitary Stimulated by impulses from hypothalamic neurons in response to increased osmolality of blood or decreased blood volume Kidneys Hormone Actions Growth Hormone (GH) Stimulates somatic growth; Mobilizes fats; Spares glucose Thyroid-Stimulating Hormone (TSH) Stimulates thyroid gland to release thyroid hormone Adrenocorticotropic Hormone Promotes release of glucocorticoids and androgens Follicle-Stimulating Hormone (FSH) In females, stimulates ovarian follicle maturation and estrogen production; In males, stimulates sperm production Luteinizing Hormone (LH) In females, triggers ovulation and stimulates ovarian production of estrogen and progesterone; In males, promotes testosterone production Prolactin (PRL) Promotes lactation Oxytocin Stimulates uterine contractions; Initiates labor; Breast: Initiates milk ejection Antidiuretic Hormone (ADH) Stimulates kidney tubule cells to reabsorb water Study Chart!
