GH - Growth Hormone - Anterior Pituitary Target Organs of GH - Liver, muscle, bone, cartilage and other tissues. anabolic hormone, stimulates somatic growth, metabolizes fats spares glucose. Effects of Hypo/Hyper Secretion of GH - Pituitary Dwarfism in children / Gigantism in children, acromegaly in adults. TSH - Thyroid Stimulated Hormone - Anterior Pituitary Target Organs of TSH - Thyroid gland stimulates thyroid gland to release thyroid hormones Effects of Hypo/Hyper Secretion of TSH - cretinism in children myxedema in adults / hyperthyroidism, effects similar to those of Graves disease in which antibodies mimic TSH ACTH - Adrenocoricotropic hormone - Anterior Pituitary Target Organs of ACTH - Adrenal Cortex promotes release of glucocorticoids and androgens Effects of Hypo/Hyper Secretion of ACTH - rare / crushing disease FSH - Follicle stimulating hormone - anterior pituitary Target Organs of FSH - Ovaries and testes in females stimulates ovarian follicle maturation and estrogen production in males stimulates sperm production Effects of Hypo/Hyper Secretion of FSH - failure of sexual maturation / no important effects LH - Luteinizing Hormone - anterior pituitary Target Organs of LH - ovaries and testes in females triggers ovulation and stimulates ovarian production of estrogen and progesterone in males promotes testosterone production. Effects of Hypo/Hyper Secretion of LH - Same as FSH PRL - Prolactin - anterior pituitary Target organs of PRL - breast secretory tissue promotion of lactation Effects of Hypo/Hyper Secretion of PRL - poor milk production in nursing women / inappropriate milk production cessation o menses in females impotence in males GH Stimulated / Inhibited by - GHRH /GH and IGF TSH Stimulated / Inhibited by - TRH / GHIH ACTH Stimulated / Inhibited by - CRH / glucocorticoids FSH Stimulated / Inhibited by - GnRH / estrogen and Testosterone LH Stimulated / Inhibited by - GnRH / estrogen and progesterone and testosterone PRL Stimulated / Inhibited by - PIH / PIH Oxytocin Stimulated / Inhibited by - impulses from hypothalamic neurons in responce to cervical/uterine stretching and suckling of infant Oxytocin - posterior pituitary ADH - Antidiuretic Hormone - posterior pituitary ADH Organs Effected - kidneys ADH Hypo/Hyper Secretion effects - diabetes insipidus/syndrome of inappropriate ADH secretion ADH Stimulated / Inhibited by - impulses from hypothalamic neurons in response to incread osmolaity of blood or decreased blood volume/ adequate hydration of the body and by alcohol the nervous system - The Endocrine System acts with _____ to coordinate and integrate the activity of body cells Pineal Gland - A hormone-secreting part of the diencephalon of the brain thought to be involved in setting the biological clock and influencing reproductive function. Hypothalamus - Region of the diencephalon forming the floor of the third ventricle of the brain.
