- A. The fundus
- B. The body
- C. The cervix
- D. The uterine tube
Explanation: The cervix is the lower, narrow part of the uterus that projects into the vagina.
Correct answer: The cervix- A. 23 chromosomes
- B. .length 46 chromosomes
- C. 44 chromosomes
- D. 92 chromosomes
Explanation: A normal sperm or ovum is haploid and contains 23 chromosomes. Fertilisation restores the diploid number of 46 chromosomes in the zygote…
Correct answer: 23 chromosomes- A. The fall in ovarian hormones causes endometrial shedding
- B. The rise in human chorionic gonadotropin causes uterine bleeding
- C. The sudden release of follicle-stimulating hormone destroys the endometrium
- D. The increase in oxytocin causes the functional layer to detach
Explanation: When the corpus luteum regresses, progesterone and estrogen levels fall, causing the functional endometrial layer to shed.
Correct answer: The fall in ovarian hormones causes endometrial shedding- A. Granulosa cells
- B. Theca interna cells
- C. Corpus albicans cells
- D. Germinal epithelial cells
Explanation: Theca interna cells respond to luteinizing hormone and produce androgen precursors.
Correct answer: Theca interna cells- A. Prophase I of meiosis
- B. Metaphase I of meiosis
- C. Prophase II of meiosis
- D. Metaphase II of meiosis
Explanation: Primary oocytes begin meiosis before birth and remain arrested in prophase I until selected for maturation.
Correct answer: Prophase I of meiosis426. Which event allows a sperm to penetrate the zona pellucida after it contacts the secondary oocyte?
- A. The acrosome reaction
- B. The menstrual reaction
- C. The luteal reaction
- D. The endometrial reaction
Explanation: The acrosome reaction releases enzymes from the sperm head that help it penetrate the zona pellucida.
Correct answer: The acrosome reaction- A. Human chorionic gonadotropin
- B. Follicle-stimulating hormone
- C. Prolactin
- D. Oxytocin
Explanation: The early trophoblast produces human chorionic gonadotropin, which supports the corpus luteum and its progesterone secretion.
Correct answer: Human chorionic gonadotropin- A. The iliac crest
- B. The ischial spines
- C. The pubic symphysis
- D. The sacral promontory
Explanation: The ischial spines project inward and form an important landmark for assessing the midpelvis and fetal station.
Correct answer: The ischial spines429. A patient asks what the placenta develops from during early pregnancy. Which answer is correct?
- A. The trophoblast and maternal endometrium
- B. The corpus luteum and cervical mucus
- C. The zona pellucida and ovarian stroma
- D. The myometrium and uterine peritoneum
Explanation: The fetal part of the placenta develops mainly from the trophoblast, while the maternal part develops from the modified endometrium.
Correct answer: The trophoblast and maternal endometrium- A. Arrange urgent assessment for possible ruptured ectopic pregnancy
- B. Advise bed rest and repeat a pregnancy test next week
- C. Offer oral fluids and document the pain for routine review
- D. Teach her that mild discomfort is normal in early pregnancy
Explanation: The symptoms suggest internal bleeding from a possible ruptured ectopic pregnancy, so urgent assessment is required.
Correct answer: Arrange urgent assessment for possible ruptured ectopic pregnancy- A. Endometrium
- B. Myometrium
- C. Perimetrium
- D. Parametrium
Explanation: The myometrium is the thick smooth-muscle layer of the uterus and produces contractions during labour.
Correct answer: Myometrium- A. Seminal vesicle
- B. Prostate gland
- C. Bulbourethral gland
- D. Epididymis
Explanation: The prostate surrounds the proximal urethra and contributes a thin, slightly alkaline fluid to semen.
Correct answer: Prostate gland433. Which cells in the seminiferous tubules provide nourishment and support to developing sperm cells?
- A. Leydig cells
- B. Sertoli cells
- C. Prostatic cells
- D. Bulbourethral cells
Explanation: Sertoli cells support, nourish and regulate developing sperm within the seminiferous tubules.
Correct answer: Sertoli cells- A. A sustained slight rise in temperature
- B. A sustained fall in temperature
- C. A sudden rise before menstruation only
- D. No temperature change throughout the cycle
Explanation: Progesterone released after ovulation raises basal body temperature slightly, and the rise remains during the luteal phase.
Correct answer: A sustained slight rise in temperature435. Which type of cell division produces genetically different haploid gametes from diploid germ cells?
- A. Mitosis
- B. Meiosis
- C. Binary fission
- D. Budding
Explanation: Meiosis reduces the chromosome number by half and produces genetically varied gametes.
Correct answer: Meiosis- A. The chromosome carried by the ovum
- B. The chromosome carried by the sperm
- C. The number of polar bodies formed
- D. The thickness of the zona pellucida
Explanation: The ovum normally contributes an X chromosome, whereas the sperm contributes either an X or a Y chromosome.
Correct answer: The chromosome carried by the sperm- A. Sperm may remain viable in the female tract for several days
- B. The ovum remains viable for about one menstrual cycle
- C. Implantation occurs immediately after intercourse
- D. Menstruation permanently stores sperm in the uterus
Explanation: Sperm can remain viable in favourable cervical mucus for several days, so they may be present when ovulation occurs.
Correct answer: Sperm may remain viable in the female tract for several days- A. Trophoblast
- B. Inner cell mass
- C. Zona pellucida
- D. Chorionic cavity
Explanation: The inner cell mass, also called the embryoblast, develops into the embryo proper.
Correct answer: Inner cell mass- A. Decidua
- B. Amnion
- C. Chorion
- D. Allantois
Explanation: The endometrium undergoes pregnancy-related changes and is called the decidua after implantation.
Correct answer: Decidua- A. Labia majora
- B. Cervix
- C. Uterine tube
- D. Endometrium
Explanation: The labia majora are folds of skin forming part of the vulva and help protect the external genital openings.
Correct answer: Labia majora
