D

A. oogonium - primary follicle

B. primary oocyte - Graafian follicle

C. secondary oocyte - secondary follicle

D. secondary oocyte - mature follicle

E. ovum - mature follicle

C

Which is NOT a function of estrogens?

A. promoting development and maintenance of secondary sex characteristics.

B. increasing protein anabolism.

C. increasing blood cholesterol.

D. inhibiting release of GnRH by the hypothalamus.

E. inhibiting secretion of FSH and LH by the anterior pituitary.

A

The last part of the preovulatory phase is characterized by

A. positive feedback caused by high levels of estrogen acting on cells releasing GnRH.

B. positive feedback caused by high levels of progesterone acting on cells secreting estrogen.

C. negative feedback caused by high levels of estrogen acting on cells releasing GnRH.

D. negative feedback caused by high levels of progesterone acting on cells secreting estrogen.

E. negative feedback from high levels of progesterone acting on cells releasing GnRH.

D

The corpus luteum may

1. degenerate into a corpus albicans if fertilization did not occur.

2. be rescued from degeneration by HCG if fertilization occurred.

3. continue to produce estrogen until the next follicle is ovulated.

A. 1 only

B. 2 only

C. 3 only

D. 1 and 2 are correct

E. 1, 2, and 3 are correct

B

Which is released at ovulation?

A. an ovum

B. a secondary oocyte

C. a primary oocyte

D. an oogonium

E

Which of the following statements is INCORRECT?

A. Gonadotropin-releasing hormone (GnRH) is secreted by the hypothalamus and controls the ovarian and uterine cycles by stimulating release of follicle stimulating hormone and luteinizing hormone.

B. Follicle stimulating hormone initiates follicular growth and luteinizing hormone stimulates more development of ovarian follicles.

C. Luteinizing hormone stimulates ovulation, corpus luteum formation and secretion of estrogen and progesterone by the corpus luteum.

D. Inhibin, secreted by the granulosa cells of the growing follicles and by the corpus luteum, inhibits secretion of FSH and LH

E. Progesterone stimulates contraction of the myometrium.

E

Which of the following statements is correct?

A. In the menstrual phase, follicle stimulating hormone stimulates development of secondary follicles in the ovaries and prostaglandins cause loss of the stratum functionalis.

B. In the preovulatory phase, secondary follicles start to secrete estrogens and inhibin. One becomes a dominant follicle and secretes estrogens and inhibin causing decreased FSH secretion leading to atresia of less developed follicles. In the uterus, the endometrium undergoes repair under the influence of estrogens.

C. In ovulation, release of luteinizing hormone causes release of the secondary oocyte.

D. In the postovulatory phase, progesterone and estrogens are secreted by the corpus luteum promote thickening of the endometrium preparing for implantation. If no pregnancy occurs, progesterone and estrogen levels drop and menstruation occurs.

E. All of these statements are correct.

B

The increase of GnRH causes all of the following except

A. the release of follicle-stimulating hormone

B. the release of corticotropin-releasing hormone

C. the release of luteinizing hormone.

D. None of these.

D

A surge of LH causes

A. transformation of the ruptured follicle into the corpus luteum.

B. the release of the secondary oocyte.

C. a decline in estrogen production.

D. all of these.

D

Which of the following are produced in and released from the ovaries?

A. Primary oocytes, prolactin and estrogen

B. Secondary oocytes, progesterone and oxytocin

C. Tertiary oocytes, oxytocin and estrogen

D. Secondary oocytes, estrogen and progesterone

E. Primary oocytes, estrogen and testosterone

C

C

After ovulation, the corpus luteum releases _____ to prepare the endometrium for implantation.
