Anatomy and Physiology of Female Reproductive System Quiz (Part 2)

51. In which specific part of the fallopian tube does fertilization usually take place?
Answer: B. Ampulla
Rationale: The ampulla is the widest and longest portion of the fallopian tube, making it the most common site for sperm and ovum fertilization.
52. How many hours after ovulation does an unfertilized ovum remain viable for fertilization?
Answer: A. 12 to 24 hours
Rationale: Following ovulation, the human ovum degenerates if it is not fertilized within approximately 12 to 24 hours.
53. The process by which spermatozoa undergo structural and metabolic changes in the female reproductive tract to gain the ability to fertilize an ovum is called:
Answer: B. Capacitation
Rationale: Capacitation takes about 7 hours in the female reproductive tract, during which the glycoprotein coat is removed from the plasma membrane overlying the acrosomal region of spermatozoa.
54. What prevents additional sperm from entering the ovum once fertilization has occurred?
Answer: C. Cortical and zonar reactions
Rationale: Upon fertilization, the release of cortical granules from the egg alters the zona pellucida structure, preventing polyspermy.
55. The solid mass of 16 or more cells formed by successive cleavages of the fertilized ovum is known as the:
Answer: B. Morula
Rationale: The morula is a mulberry-like solid sphere of blastomeres formed roughly 3 days after fertilization as the zygote travels down the fallopian tube.
56. Implantation of the blastocyst into the uterine wall typically occurs how many days after fertilization?
Answer: C. 6 to 10 days
Rationale: The blastocyst begins to embed in the secretory endometrium about 6 days after fertilization and completes the process by the 10th or 11th day.
57. Following successful implantation, the modified endometrium of pregnancy is renamed the:
Answer: B. Decidua
Rationale: The term “decidua” refers to the highly vascularized functional layer of the endometrium during pregnancy, which is shed after birth.
58. Which portion of the decidua covers the blastocyst directly after implantation?
Answer: A. Decidua capsularis
Rationale: The decidua capsularis seals over the buried blastocyst. The decidua basalis forms the maternal side of the placenta.
59. The inner cell mass of the blastocyst eventually develops into the:
Answer: B. Embryo and fetus
Rationale: The blastocyst differentiates into an outer layer of cells (trophoblast, which forms the placenta) and an inner cell mass (embryoblast, which forms the embryo).
60. Slight spotting or bleeding that may occur around the time of the missed period due to blastocyst embedding is termed:
Answer: B. Hartman’s sign
Rationale: Hartman’s sign refers to mild implantation bleeding or spotting that occurs as the chorionic villi erode maternal blood vessels in the endometrium.
61. Which embryonic structure forms the fetal contribution to the placenta?
Answer: B. Chorion frondosum
Rationale: The chorion frondosum (bushy chorion) develops projection villi that combine with the maternal decidua basalis to form the functional placenta.
62. At full term, what is the approximate average weight of a normal placenta?
Answer: B. 500 grams
Rationale: A healthy full-term placenta weighs roughly 500 grams, which is typically about one-sixth (1:6) of the newborn’s birth weight.
63. Which cell layer of the trophoblast directly synthesizes Human Chorionic Gonadotropin (hCG)?
Answer: A. Syncytiotrophoblast
Rationale: The outer syncytiotrophoblast layer secretes hCG, which sustains the corpus luteum during early pregnancy to preserve progesterone production.
64. The primary function of human placental lactogen (hPL) is to:
Answer: C. Alter maternal metabolism to ensure glucose availability to the fetus
Rationale: hPL acts as an insulin antagonist in the mother, decreasing maternal glucose utilization and ensuring a steady supply of glucose for the developing fetus.
65. Maternal and fetal blood mix freely under normal conditions within the placenta.
Answer: B. False
Rationale: Maternal and fetal circulations are separated by the placental barrier. Exchange of nutrients and waste occurs across villi via diffusion and active transport without direct blood mixing.
66. The functional units of the placenta where metabolic and gas exchange occurs are called:
Answer: A. Cotyledons
Rationale: A full-term maternal placental surface is partitioned into 15 to 20 lobes called cotyledons, each containing branches of chorionic villi.
67. Oxygenated blood is carried from the placenta to the fetus by which structure?
Answer: A. One umbilical vein
Rationale: Unlike typical postnatal circulation, the single umbilical vein carries highly oxygenated, nutrient-rich blood from the placenta to the fetal heart.
68. Deoxygenated blood and fetal waste products travel back to the placenta through the:
Answer: B. Two umbilical arteries
Rationale: The two umbilical arteries carry deoxygenated blood and metabolic waste away from the fetal internal iliac arteries back to the placenta.
69. The specialized gelatinous connective tissue that surrounds and protects the blood vessels within the umbilical cord is called:
Answer: B. Wharton’s jelly
Rationale: Wharton’s jelly prevents compression of the umbilical cord vessels, maintaining stable blood flow between the fetus and the placenta.
70. Insertion of the umbilical cord into the margins/edge of the placenta rather than the center is called a:
Answer: A. Battledore placenta
Rationale: A battledore (marginal) insertion occurs when the cord attaches at the periphery of the placenta. Velamentous insertion involves the cord anchoring into the fetal membranes instead of the placenta proper.
71. Which of the two fetal membranes forms the smooth, tough inner sac containing the amniotic fluid?
Answer: A. Amnion
Rationale: The amnion is the glistening inner fetal membrane that lines the amniotic cavity. The chorion is the outer membrane adjacent to the decidua.
72. In the second half of pregnancy, the major contributor to the volume of amniotic fluid is:
Answer: B. Fetal urine
Rationale: From the second trimester onward, fetal urination serves as the primary source of amniotic fluid volume. The fetus balances this by swallowing the fluid.
73. What is the normal volume of amniotic fluid at full term (36–38 weeks)?
Answer: B. 600 to 1000 mL
Rationale: Amniotic fluid volume peaks around 36-38 weeks at roughly 800 mL, before decreasing slightly as full-term delivery approaches.
74. Oligohydramnios is defined as an amniotic fluid volume of less than:
Answer: A. 200 mL
Rationale: Oligohydramnios is a clinical deficiency of amniotic fluid, characterized by an overall volume below 200 mL or an Amniotic Fluid Index (AFI) under 5 cm.
75. Polyhydramnios (hydramnios) is defined as an amniotic fluid volume exceeding:
Answer: B. 2000 mL
Rationale: Polyhydramnios is an excessive accumulation of amniotic fluid exceeding 2000 mL, commonly linked with gestational diabetes or fetal anomalies like esophageal atresia.
76. What is the normal pH of amniotic fluid?
Answer: B. 7.0 to 7.5 (Neutral to slightly Alkaline)
Rationale: Amniotic fluid is slightly alkaline, which distinguishes it from acidic vaginal secretions (pH 4.0-5.0) during Nitrazine paper testing for ruptured membranes.
77. Greenish discoloration of the amniotic fluid during labor indicates the presence of:
Answer: B. Meconium
Rationale: Green fluid indicates fetal passing of meconium (first stool), often secondary to intrauterine hypoxia or stress.
78. Golden-colored amniotic fluid obtained during amniocentesis indicates:
Answer: B. Rh incompatibility (hemolysis)
Rationale: Golden fluid points to elevated bilirubin levels from fetal erythrocyte destruction in Rh-isoimmunization.
79. A dark, tobacco-juice colored amniotic fluid is a clinical sign of:
Answer: B. Intrauterine fetal death (IUFD)
Rationale: Dark brown or tobacco-juice fluid occurs following fetal demise due to tissue autolysis and blood breakdown components.
80. Saffron-colored amniotic fluid is most typically seen in cases of:
Answer: A. Post-maturity
Rationale: Saffron-tinted fluid is associated with post-term pregnancies (past 42 weeks) due to early meconium passage or skin desquamation changes.
81. Which maternal immunoglobulin class can cross the placenta to provide passive immunity to the fetus?
Answer: B. IgG
Rationale: IgG is the smallest immunoglobulin molecule and the only class capable of crossing the placental barrier via active transport mechanisms.
82. Oligohydramnios is highly associated with which fetal congenital abnormality?
Answer: A. Renal agenesis (Potter’s syndrome)
Rationale: Because fetal urine is the main source of amniotic fluid later in pregnancy, a lack of fetal kidney development results in profound oligohydramnios.
83. The tiny, finger-like projections that emerge from the trophoblast layer to erode maternal decidua are called:
Answer: B. Chorionic villi
Rationale: Chorionic villi maximize the surface area for diffusion between maternal vascular lakes and fetal capillary loops.
84. At what week of gestation does the placenta completely take over progesterone production from the corpus luteum?
Answer: C. 12th week
Rationale: By the end of the first trimester (around 11-12 weeks), the luteo-placental shift is complete, and the placenta assumes full endocrine maintenance of pregnancy.
85. The structure formed when the extraembryonic mesoderm lines the trophoblast is the:
Answer: A. Chorion
Rationale: The chorion is the outermost fetal membrane consisting of the trophoblast layers backed by extraembryonic somatic mesoderm.
86. Which test uses the presence of amniotic fluid crystallization patterns to confirm ruptured membranes?
Answer: B. Ferning test
Rationale: When dried on a clean glass slide, amniotic fluid displays a distinct palm-leaf-like crystallization pattern (ferning) due to its high sodium chloride concentration.
87. A condition where the placenta implants abnormally deeply, adhering directly to the myometrium without invading the muscle, is called:
Answer: A. Placenta accreta
Rationale: Placenta accreta occurs when the decidua basalis layer is defective, causing chorionic villi to attach directly onto the uterine muscle wall.
88. When placental chorionic villi fully invade and penetrate through the myometrium up to the serosa layer, it is classified as:
Answer: C. Placenta percreta
Rationale: Placenta percreta is the most severe form, where villi invade through the entire uterine wall and may attach to adjacent visceral organs like the bladder.
89. The maternal side of the placenta is called the:
Answer: B. Maternal surface (Duncan mechanism side)
Rationale: The maternal surface is rough, dark red, and divided into cotyledons, often called the “Dirty Duncan” surface when it presents first during third-stage delivery.
90. The shiny, smooth fetal side of the placenta covered by the amnion membrane is called the:
Answer: A. Schultze surface
Rationale: The fetal surface is known as the “Shiny Schultze” and features umbilical blood vessels branching out smoothly beneath the transparent amnion membrane.
91. How many weeks does a typical human pregnancy last when calculated from the first day of the last menstrual period (LMP)?
Answer: C. 40 weeks
Rationale: Gestational age is standardly computed as 280 days, 40 weeks, or 10 lunar months, starting from the LMP date.
92. The true length of human pregnancy from the exact time of conception is:
Answer: B. 266 days
Rationale: Conceptual age is 266 days (38 weeks), because fertilization happens approximately 14 days following the last menstrual period onset.
93. What is the name of the accessory placental lobe that develops separate from the main placental mass?
Answer: A. Succenturiate placenta
Rationale: A succenturiate placenta features one or more small accessory lobes connected to the main body via fetal vascular branches running across the membranes.
94. Amniotic fluid volume assessment via ultrasound that totals the deepest vertical pockets of fluid across four quadrants is called the:
Answer: B. Amniotic Fluid Index (AFI)
Rationale: AFI is calculated by measuring the depth of fluid in four quadrants of the uterus. Normal AFI values typically range between 5 cm and 25 cm.
95. Phosphatidylglycerol (PG) and Lecithin-to-Sphingomyelin (L/S) ratios within amniotic fluid are analyzed to determine:
Answer: B. Fetal lung maturity
Rationale: Surfactant components like lecithin and PG build up in amniotic fluid as lungs develop; an L/S ratio greater than 2:1 indicates low risk for Respiratory Distress Syndrome.
96. Elevated alpha-fetoprotein (AFP) levels in maternal serum or amniotic fluid sampling are indicative of:
Answer: A. Neural tube defects (e.g., Spina Bifida)
Rationale: Open neural tube defects cause fetal AFP to leak directly into the surrounding amniotic fluid, raising levels above reference baselines. Conversely, Down syndrome is associated with low AFP levels.
97. The process of physiological remodeling of maternal spiral arteries by invasive cytotrophoblasts is crucial to:
Answer: B. Establish a high-flow, low-resistance uteroplacental circulation
Rationale: Remodeling converts narrow spiral arteries into wide vascular channels, ensuring adequate placental perfusion. Defective remodeling is linked to preeclampsia.
98. Amniotic fluid contains which of the following protective components against infection?
Answer: A. Antimicrobial peptides, lysozymes, and transferrin
Rationale: Amniotic fluid possesses natural bacteriostatic and antimicrobial elements that help protect the sterile intrauterine space from ascending infections.
99. By what mechanism do water and electrolytes primarily exchange across the amniotic membrane?
Answer: A. Simple diffusion and intramembranous pathway transport
Rationale: Water and solutes constantly shift dynamically between the fetus, placenta, and amniotic cavity via highly permeable pathways.
100. The whitish, cheesy substance covering the skin of the fetus that can flake off into the amniotic fluid is called:
Answer: B. Vernix caseosa
Rationale: Vernix caseosa is a lipid-rich protective coating secreted by fetal sebaceous glands that safeguards fetal skin from maceration by amniotic fluid.
