- Which of the following statements regarding pituitary hormones is FALSE? Group of answer choices Luteinizing hormone, an anterior pituitary hormone, triggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogens. Antidiuretic hormone, released by the posterior pituitary, causes urine volume to increase and blood volume to decrease The hypothalamus makes oxytocin and antidiuretic hormone, which are transported the posterior pituitary for storage. Hyposecretion of follicle-stimulating hormone or luteinizing hormone leads to sterility in both males and females.Which of the following statements regarding pituitary hormones is FALSE? Adrenocorticotropic hormone, released by the anterior pituitary, targets the adrenal medulla to increase cardiac output and blood flow. Luteinizing hormone, an anterior pituitary hormone, triggers ovulation of an egg from the ovary and causes the ruptured follicle to produce progesterone and some estrogens. Hyposecretion of follicle-stimulating hormone or luteinizing hormone leads to sterility in both males and females. O The hypothalamus makes oxytocin and antidiuretic hormone, which are transported the posterior pituitary for storage.Choose the item below controlled by ADH: the level of glucose in the blood the amount of water re-absorbed in the nephron O the development of the lining of the uterus the release of an ovum from the ovary the uptake of calcium by the bones
- Which hormone is correctly paired up with its function? ADH: causes smooth muscle contractions in the uterus O T4: decreases cellular activities and chemical reactions in the body Calcitonin: increases the levels of calcium in the blood None of the hormones are correctly paired up with its function.A woman is in labor. The size of the fetus combined with the contractions of the uterine muscular layer stretches the uterine wall, stimulating stretch receptors in the cervix. Signals from these receptors are conducted through nerves to the hypothalamus/posterior pituitary. The hypothalamus/posterior pituitary releases oxytocin. The oxytocin travels through the blood and stimulates the smooth muscle layer of the uterus. Oxytocin has two effects on the uterine smooth muscle:1. Itdirectlystimulatesthesmoothmuscletocontractmorefrequentlyandmoreforcefully.2. Itcausestheuterinewalltoreleaseprostaglandins,whichincreasethefrequencyandforceofthe contractions even more.These effects push the fetus more forcefully into the cervix, stimulating the stretch receptors further. The receptors send additional impulses to the hypothalamus/posterior pituitary. The increased activation of the hypothalamus/posterior pituitary stimulates release of additional oxytocin, which further stimulates the uterus.…Which of the following is/are true with regards to hormones in the reproductive tract? Estrogen secretion is stimulated exclusively by LH. Progesterone is secreted by ovarian follicles & the corpus luteum. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum. All of the above
- An endocrinologist is supervised by a patient, 40 years old, who has an inferiority of the function of the cortical substance of the adrenal glands, which manifests itself by decreasing the amount of the aldosterone hormone in the blood. What cortical cells are affected? O Zona reticularis cells cells of the X-zone Epinephrocytes The cells of the glomerular zone Zona fasciculate cellsWhich statement about antidiuretic hormone is TRUE? Antidiuretic hormone increases urine production. Antidiuretic hormone reduces urine production. Antidiuretic hormone is made by the kidneys. Excessive secretion of antidiuretic hormone causes dehydration.A hormone secreted by the anterior pituitary regulates the concentration of sodium ions in extracellular fluid. Group of answer choices True False
- Which of the following is/are true with regards hormones in the reproductive tract? * All the choices Progesterone is secreted by ovarian follicles & the corpus luteum. Estrogen secretion is stimulated exclusively by LH. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum.Sheehan's syndrome is an endocrine disorder caused by blood loss during or after parturition. The blood loss damages the pituitary gland, leading to the underproduction of hormones. The symptoms of Sheehan's syndrome include lack of menstruation, inability to produce milk, fatigue, intolerance to cold, weight gain, low blood pressure, low sodium levels, and suppressed immune system. Some Hormones of the Endocrine System 1. TRH 2. GNRH 3. Thyroxine 4. Epinephrine 5. FSH & LH 6. Prolactin 7. Oxytocin 8. PTH 9. Calcitonin 10. Cortisol 11. ADH 12. Aldosterone 13. Inhibin The hormones that need to be administered to individuals affected by Sheehan's syndrome are and Record your answer in the highest-to-lowest numerical order.Which of the following is not a hormone?a. prolactinb. prolactin-inhibiting hormonec. thyroxine-binding globulind. atrial natriuretic peptidee. cortisol
