Intermediate Infundibulum Quiz

Q1. Which anatomical feature distinguishes the infundibulum from the ampulla?

• It is the funnel-shaped fimbria-bearing lateral end
• It is the segment embedded in the uterine wall
• It is the narrow medial segment adjacent to the uterus
• It is the lower portion of the uterine cavity

Q2. Why can an oocyte enter the infundibulum even though the ovary is not directly continuous with the tubal lumen?

• The uterine cavity opens directly onto the ovary
• The ovarian ligament contains a patent lumen
• The abdominal ostium communicates with the peritoneal cavity
• The ovary contains a duct continuous with the ampulla

Q3. How are the fimbriae related structurally to the infundibulum?

• They are folds within the ovarian cortex
• They arise from the uterine fundus
• They project from the margin of the infundibulum
• They form the muscular wall of the ampulla

Q4. Which epithelium lines the mucosa of the infundibular region?

• Transitional epithelium
• Keratinized stratified squamous epithelium
• Stratified cuboidal epithelium
• Simple columnar epithelium with ciliated and secretory cells

Q5. Which portion of the broad ligament is associated with the uterine tube and its lateral segments?

• Mesometrium only
• Round ligament
• Mesosalpinx
• Uterosacral ligament

Q6. Which arterial sources contribute to the blood supply of the lateral uterine tube near the infundibulum?

• Femoral and profunda femoris arteries
• Superior and inferior mesenteric arteries
• Ovarian and uterine arterial branches
• Inferior epigastric and obturator arteries only

Q7. Where is an ovulated oocyte immediately before it reaches the infundibulum?

• In the local peritoneal cavity
• In the cervical canal
• In the ureter
• In the uterine cavity

Q8. Which processes assist movement of the oocyte from the infundibular region into the uterine tube?

• Gravity as the only mechanism
• Ureteric peristalsis
• Skeletal muscle contraction alone
• Fimbrial and ciliary activity with tubal transport mechanisms

Q9. What is the key anatomical significance of the abdominal ostium?

• It connects the tube with the urinary bladder
• It connects the tubal lumen directly with ovarian tissue
• It connects the cervical canal with the peritoneal cavity
• It connects the tubal lumen with the peritoneal cavity

Q10. How is the ovarian fimbria related to the infundibulum?

• It passes through the uterine myometrium
• It extends from the infundibulum to the ovary
• It extends from the cervix to the ovary
• It forms the uterine ostium
