- A. Ampulla of the uterine tube
- B. Cervix of the uterus
- C. Endometrium of the uterus
- D. Vagina near the cervix
Explanation: Fertilization usually occurs in the ampulla, the wider part of the uterine tube.
Correct answer: Ampulla of the uterine tube- A. Follicle-stimulating hormone
- B. Luteinizing hormone
- C. Oestrogen from the corpus luteum
- D. Progesterone from the follicle
Explanation: A mid-cycle surge of luteinizing hormone causes rupture of the mature ovarian follicle and ovulation.
Correct answer: Luteinizing hormone243. A nurse explains the main function of progesterone after ovulation. Which statement is correct?
- A. It stimulates sperm production in the testes
- B. It prepares and maintains the endometrium
- C. It causes development of the ovarian follicle
- D. It produces the mid-cycle ovulatory surge
Explanation: Progesterone from the corpus luteum changes the endometrium into a secretory lining suitable for implantation and helps maintain it.
Correct answer: It prepares and maintains the endometrium- A. Seminiferous tubules of the testes
- B. Epididymis beside each testis
- C. Prostate gland below the bladder
- D. Vas deferens within the spermatic cord
Explanation: Spermatogenesis occurs in the seminiferous tubules of the testes. The epididymis stores and supports maturation of sperm, whereas the…
Correct answer: Seminiferous tubules of the testes- A. Seminal vesicle
- B. Seminiferous tubule
- C. Epididymis
- D. Vas deferens
Explanation: The seminal vesicles are accessory glands that add fructose-rich fluid to semen.
Correct answer: Seminal vesicle- A. Testosterone
- B. Progesterone
- C. Follicle-stimulating hormone
- D. Human chorionic gonadotropin
Explanation: Leydig cells, also called interstitial cells, produce testosterone in response to luteinizing hormone.
Correct answer: Testosterone- A. Spermatogenesis produces four functional gametes from one primary cell
- B. Oogenesis produces four equal-sized ova from one primary oocyte
- C. Spermatogenesis begins before birth and stops at puberty
- D. Oogenesis continues continuously throughout adult life
Explanation: One primary spermatocyte can produce four functional sperm cells after meiosis.
Correct answer: Spermatogenesis produces four functional gametes from one primary cell- A. Growth of a dominant ovarian follicle
- B. Formation of the corpus luteum
- C. Degeneration of the endometrium
- D. Release of progesterone from the placenta
Explanation: The follicular phase includes growth and maturation of a dominant ovarian follicle before ovulation.
Correct answer: Growth of a dominant ovarian follicle- A. Trophoblastic tissue begins producing human chorionic gonadotropin
- B. The anterior pituitary releases a large amount of progesterone
- C. The ovarian follicle releases a second mature oocyte
- D. The uterus immediately begins regular menstrual bleeding
Explanation: After implantation, trophoblastic tissue produces human chorionic gonadotropin, which supports the corpus luteum and its progesterone…
Correct answer: Trophoblastic tissue begins producing human chorionic gonadotropin- A. It is where sperm mature and are stored
- B. It is where testosterone is mainly produced
- C. It is where semen is mixed with prostatic fluid
- D. It is where sperm are formed from primary oocytes
Explanation: The epididymis is a coiled duct on the testis where sperm mature, gain motility, and are temporarily stored.
Correct answer: It is where sperm mature and are stored- A. Follicle-stimulating hormone
- B. Luteinizing hormone
- C. Progesterone
- D. Human chorionic gonadotropin
Explanation: Follicle-stimulating hormone, or FSH, promotes the growth of ovarian follicles and supports oestrogen production.
Correct answer: Follicle-stimulating hormone- A. Functional layer of the endometrium
- B. Basal layer of the endometrium
- C. Myometrium of the uterus
- D. Perimetrium of the uterus
Explanation: The functional layer of the endometrium thickens during the cycle and is shed when hormone levels fall.
Correct answer: Functional layer of the endometrium- A. Fallopian tube
- B. Cervical canal
- C. Vaginal canal
- D. Urethral canal
Explanation: The fertilized ovum travels through the fallopian tube toward the uterine cavity.
Correct answer: Fallopian tube- A. It rebuilds and thickens the endometrium
- B. It maintains the uterine lining after ovulation
- C. It causes milk production after childbirth
- D. It prevents follicle development in the ovary
Explanation: Oestrogen produced by developing ovarian follicles stimulates proliferation and thickening of the endometrium.
Correct answer: It rebuilds and thickens the endometrium- A. Primary oocytes are formed before birth
- B. New primary oocytes are formed throughout adult life
- C. Oogenesis normally produces four mature ova from one primary oocyte
- D. Oogenesis begins only after the first menstrual period
Explanation: Most primary oocytes are formed during fetal life and remain arrested until reproductive maturity.
Correct answer: Primary oocytes are formed before birth- A. The lining of the uterine body
- B. The muscular wall of the uterus
- C. The inner surface of the ovary
- D. The lining of the urinary bladder
Explanation: Normal implantation occurs in the endometrium, usually in the upper part of the uterine body.
Correct answer: The lining of the uterine body- A. Ovary
- B. Uterus
- C. Fallopian tube
- D. Vagina
Explanation: The ovary is the female gonad because it produces ova and secretes reproductive hormones.
Correct answer: Ovary- A. It degenerates and hormone levels fall
- B. It enlarges and produces human chorionic gonadotropin
- C. It changes into a mature ovarian follicle
- D. It moves into the uterine cavity for implantation
Explanation: When pregnancy does not occur, the corpus luteum degenerates, causing progesterone and oestrogen levels to fall.
Correct answer: It degenerates and hormone levels fall259. Which accessory gland contributes a fructose-containing fluid that helps provide energy for sperm?
- A. Seminal vesicle
- B. Prostate gland
- C. Bulbourethral gland
- D. Thyroid gland
Explanation: The seminal vesicles contribute fluid containing fructose, which supplies energy for sperm movement.
Correct answer: Seminal vesicle- A. It stimulates testosterone release from Leydig cells
- B. It supports sperm production through Sertoli cells
- C. It causes ejaculation by contracting the vas deferens
- D. It promotes prostate growth after puberty
Explanation: FSH acts mainly on Sertoli cells in the seminiferous tubules and supports spermatogenesis.
Correct answer: It supports sperm production through Sertoli cells
