Alberta Biology 30: Endocrine System - Questions and Answers Where does ADH target? What is it's purpose? Nephrons of kidney & arterioles; increases water reabsorption & increases blood pressure. Which type of diabetes is caused by low ADH production? Diabetes insipidus. Which gland releases aldosterone? Adrenal glands (cortex) Where does aldosterone target? What is the DIRECT and INDIRECT effect? Kidney; sodium ion reabsorption; H20 reabsorption. What stimulates the release of aldosterone? Low blood sodium, low blood pressure, hemorrhaging What hormone stimulates the adrenal glands to release aldosterone? Where is is produced? ACTH (adrenocorticotropic hormone); anterior pituitary What is the function of estrogen in females? Development of secondary sex characteristics, thickening of endometrium. What is the function of progesterone in females? Prevents uterus from contracting, maintains endometrium. TIP: Progesterone = Pregnancy What is the function of testosterone in males? Stimulates primary & secondary sex characteristics (growth of penis, testes, etc); indirectly stimulates spermatogenesis Where is FSH produced/released? What is the role of FSH in males? Females? Anterior pituitary Males = tells Sertoli cells to begin spermatogenesis in sem. tubules. Females = tells follicles in ovaries to develop. Where is LH produced/released? What is the role of LH in males? Females? Anterior pituitary Males = tells interstitial cells to produce testosterone. Females = triggers ovulation & estrogen/progesterone secretion from corpus luteum. Which hormone stimulates the release of FSH and LH? Where is it produced? GnRH (gonadotropin releasing hormone); hypothalamus. What hormone is responsible for the opening of the cervix and loosening of ligaments in the pelvis during parturition? What structure produces it? Relaxin; corpus luteum
