Oxytocin correct answer - Source: Posterior pituitary(does not synthesize hormones, it stores oxytocin produced by the hypothalamus) Target: Mammary glands Action: milk letdown -Secreted during childbirth. Increases strength of uterine contractions and stimulates milk ejection TSH (Thyroid stimulating hormone) correct answer - Source: Anterior pituitary (tropic hormones-stimulate other endocrine glands) Target: Thyroid Action: Secretion of T3 and T4 -stimulates thyroid gland to release thyroid hormones ACTH (adrenocorticotropic hormones) correct answer - Source: Anterior pituitary (tropic hormones-stimulate other endocrine glands) Target: Adrenal cortex Action: secretion of glucocorticoids -Involved in regulation of metabolism of glucose FSH (follicle stimulating hormones) correct answer - Source: anterior pituitary (tropic hormones-stimulate other endocrine glands) Target: Ovaries, testes Action: Regulates oogenesis and spermatogenesis -Females: stimulates maturation of ovarian follicles to secrete estrogen. -Males: stimulates maturation of seminiferous tubules and sperm production LH (luteinizing hormone) correct answer - Source: anterior pituitary (tropic hormones-stimulate other endocrine glands) Target: Ovaries, testes Action: Regulates oogenesis and spermatogenesis -Females: stimulates formation of the corpus lute -Males: stimulates interstitial cells of the testes to produce testosterone PRL (prolactin) correct answer - Source: Anterior pituitary (hormones-directly stimulate target organs) Target: mammary glands Action: production of milk Endorphins correct answer - inhibit perception of pain; technically a neurohormone GH (Growth hormones) aka somatotropin correct answer - Source: Anterior pituitary (hormones-directly stimulate target organs) Target: Bone, muscle Action: Stimulates growth Glucagon correct answer - Source: Pancreas (alpha cells) Target: Liver Action: Increase blood glucose Insulin correct answer - Source: Pancreas (beta cells) Target: Liver, muscles, fats Action: Decreases blood glucose
