The level of a sex hormone, testosterone (T), is controlled by negativefeedback. Another hormone, gonadotropin-releasing hormone (GNRH), isreleased by the hypothalamus of the brain, which triggers the pituitarygland to release luteinizing hormone (LH). LH stimulates the gonads toproduce T. When there is too much T in the bloodstream, it feeds back onthe hypothalamus, causing it to produce less GNRH. While this does notdescribe all the feedback loops involved in regulating T, answer thefollowing questions about this particular feedback loop. b. What is the control center in this system?

Question

The level of a sex hormone, testosterone (T), is controlled by negative
feedback. Another hormone, gonadotropin-releasing hormone (GNRH), is
released by the hypothalamus of the brain, which triggers the pituitary
gland to release luteinizing hormone (LH). LH stimulates the gonads to
produce T. When there is too much T in the bloodstream, it feeds back on
the hypothalamus, causing it to produce less GNRH. While this does not
describe all the feedback loops involved in regulating T, answer the
following questions about this particular feedback loop.

b. What is the control center in this system? Explain your answer.

Secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH ) from the anterior pituitary gland . Growth of pubic and axillary hair .
increased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), ( LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ) Decreased levels of estrogen and progesterone will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to ( negative, positive, increase, decrease), (LH, FSH, GnRh, LH AND FSH) production. This normally occurs during the ( FOLLICULAR STAGE, LUTEAL STAGE ). Extremely high levels of estrogen near the end of the follicular phase will result in ( negative, positive, increase, decrease) feedback to the hypothalamus and anterior pituitary to release a large amount of ( LH, FSH, GnRh, LH AND FSH) to trigger ovulation. Some hormones are used in oral contraceptive pills to suppress the release of ( LH, FSH, GnRh, LH AND FSH) Without…
Right before the ovulation, the maturate follicle secretes high levels of estrogen which switches from negative to positive feedback regulation of the HPG axis. Positive feedback regulation of estrogen will result in __________ of estrogen levels, leading to an ____________ surge further increase; progesterone further increase; LH decrease; progesterone decrease, LH
Gonadocorticoid A. synthesized by the adrenal medulla are primarily androgens. B. Production by the adrenal gland is insignificant as compared to sex hormone release from the gonads during late puberty C. Inhibition (of secretion) is highly dependent on a negative feedback loop involving ACTH D. Hypersecretion can result in androgenital syndrome also called feminization E. All of these are correct
What is the purpose of androgen binding protein by Sertoli cells of the testes? a. Potentiates the actions of testosterone at target cells b. Prevents testosterone from diffusing out the testes c. Regulates level of testosterone via negative feedback control at the level of the anterior pituitary d. To stimulate testosterone production
Match four of the hormones of the negative feedback numbered above with their function given below. Function: Hormone: Stimulates the development of an ovum Answer Stimulates the corpus luteum to release progesterone Answer Suppresses GnRH, FSH, and LH production in the follicular phase Answer Suppresses GnRH, FSH, and LH production in the luteal phase Answer
Birth control pills are oral contraceptives taken by women to prevent pregnancies. the most effective forms of birth control pills contain estrogen and a small amount of progestin ( a synthetic hormone that mimics the effect of progesterone). The role of estrogen in the birth control pills is to: Select one: A. reduce the progesterone levels in the blood to limit the endometrium. B. negatively feedback to the anterior pituitary to suppress the production of GnRH. C. suppress the shedding of the endometrium, thus preventing mestruation. D. prevent the rise in the FSH and LH levels, thereby preventing follicle's maturation.
