- Match each hormone with its effect. oxytocin a. growth of facial hair testosterone b. uterus contracts LH c. LH, FSH are released GnRH d. surge causes ovulation FSH e. follicle develops HCG f. milk is produced prolactin g. corpus luteum is maintainedFigure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.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.
- Name the organ and cells that produce the female hormones and describe the functions of the hormonesIn the anterior pituitary region, do you see multiple cell types in each follicle or does each follicle contain a single cell type? How can you tell each cell type apart from one another? Hint: think about the names and staining.Discuss the physiological effects of estrogens and progesterone.
- In the female endocrine system, gonadotropin-releasing hormone (GnRH) is able to modulate two hormones to result in the release of a single ovum . This complex system is vulnerable to disruption with resulting abnormal uterine bleeding and infertility Gonadotropin -releasing hormone () stimulates the release of folliclestimulating hormone in addition to which the following ? Adrenocorticotropic harmone Thyroid - hormone TSH ) Opute peptide Growth hormone (GH) Luteinizing hormone (LH)Which of the following hormones controls the release of pituitary sex hormones? LH - luteinizing hormone FSH - follicle stimulating hormone GNRH - gonadotropin releasing hormone TestosteroneLuteinizing hormone (LH): Which of the following is correct ? Stimulates testosterone secretion LH surge stimulates ovulation Stimulates gonadotropin-releasing hormone (GnRH) secretion
