Which of the Following Is True of Follicular Estrogen Synthesis

D The menstrual phase of the cycle is from day 1 to day 8. A FSH and LH directly promote development of the uterine endometrium B estrogen is secreted by the developing follicle in the follicular phase of the cycle C the corpus luteum is formed from the ruptured follicle after ovulation.

Solved Question 27 1 Point According To The Two Cell Chegg Com

Which of the following is TRUE of follicular estrogen synthesis.

. Theca cells synthesize an androgen which luteal cells convert to estrogen. FSH and LH directly promote development of the uterine endometrium c. Put the events of thyroid hormone synthesis into the correct order.

C During the proliferative phase levels of progesterone rise as the follicle begins to produce more hormone. Causes hypertrophy hyperplasia of the thyroid follicular cells b. D the corpus luteum is formed from the ruptured follicle after ovulation.

According to the two-cell mechanism of follicular estrogen synthesis. Increases endocytosis of iodinated thyroglobulin within follicular cells. Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of womens ovaries and mens testes.

Men do not produce oxytocin O d. Ovulation and menstruation menstrual flow D. Sex hormones estrogens and androgens are synthesized by the adrenal glands O e.

All of the following statements referring to the uterine cycle are true except _____. TSH has all of the following actions except. Feedback to anterior pituitary to decrease FSH.

- Iodine combines with TGB to produce thyroid hormone precursors. - Thyroid hormone precursors travel to a lysosome. Sertoli cells synthesize an androgen which the granulosa cells convert to.

It also increases oestradiol production. The corpus luteum is formed during the follicular stage c. - Thyroid hormone precursors are internalized into follicular cells.

Upregulates the sodiumiodide symptorter d. 5- c Tyrosine kinase activity. 6- a Increased glucose uptake into cells.

Decreases vascularity of the thyroid gland c. Granulosa-derived inhibin may therefore participate in a paracrine mechanism that locally amplifies androgen synthesis and hence oestrogen formation in the preovulatory follicles. Select one or more.

In men follicle stimulating hormone acts on the Sertoli cells. Causes the oocyte to separate from the follicular wall. Stimulates contration of the smooth muscle surrounding the follicle.

For the 10 days following ovulation in a nonpregnant menstrual cycle. Stimulates iodination of thyroglobulin e. The LH surge creates the environment for follicular eruption by increasing the activity of the proteolytic enzymes that weaken the ovarian wall.

Prior to the LH surge LH interacts with Theca cells that are adjacent to granulosa cells in the ovary. It is the most essential hormone for the development of secondary sexual. The expression of the _____ gene results in the production of proteins that stimulate synthesis of androgens that initiate development af a male phenotype.

Uterine wall begins to thicken and increased estrogen production by the follicles E. Early follicular development in the ovaries and maximum thickening of the uterus C. C estrogen is secreted by the developing follicle in the follicular phase of the cycle.

Sertoli cells synthesize an androgen which the granulosa cells convert to dihydrotestosterone. - Follicular cells secrete thyroglobulin TGB into the colloid. Estrogen levels rise during the follicular phase of the ovarian cycle and estrogen assists with the development of the dominant follicle.

All of the following statements referring to the uterine cycle are true except _____. Inhibin has the potential to potently enhance LH-stimulated thecal androgen synthesis. Granulosa cells synthesize an androgen which the theca cells convert to estrogen.

Which of the following are TRUE. During the follicular phase the developing follicle secretes estrogen. 4- b Secretion is decreased by somatostatin somatomedins.

A During the secretory phase estrogen levels are at their highest. This estrogen does all of the following EXCEPT. 7- d Hypersecretion of Growth hormone-releasing hormone.

Follicle-stimulating hormones are glycoprotein gonadotropin secreted by the pituitary gland. These cells produce androgens which diffuse into the granulosa cells and convert to estrogen for follicular development. Estrogen is secreted by the developing follicle in the follicular phase of the cycle b.

Follicle-stimulating hormones FSH are called gonadotropins because they stimulate the gonads and control the sexual and reproductive characteristics in both male and females. According to the two-cell mechanism of follicular estrogen synthesis. In women this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation.

9- d Thyroid-stimulating hormone TSH 10- b Hyperthyroidism due to an abnormality in the hypothalamus. Which of the following is true. B If fertilization occurs the corpus luteum is maintained by a hormone secreted by the developing embryo.

The corpus luteum is formed from the ruptured follicle after ovulation. Granulosa cells synthesize an androgen which the theca cells convert to estrogen. Maintain progesterone and estrogen synthesis after ovulation has occured.

To stimulate synthesis of plasminogen activator. A FSH and LH directly promote development of the uterine endometrium. FSH stimulates the synthesis in APB androgen binding protein from Sertoli cells in seminiferous tubules O b.

Granulosa cells synthesize an androgen which the theca cells convert to estrogen. B a decrease in the levels of ovarian hormones signals menstruation. Sertoli cells synthesize an androgen which the granulosa cells convert to dihydrotestosterone.
