Intermediate Fimbriae Quiz

Q1. What anatomical feature makes the ovarian fimbria distinctive?

• It passes through the myometrium
• It forms the uterine ostium
• It attaches to the ovary
• It encloses the ovarian artery

Q2. Why can the fimbrial end receive an oocyte even though the ovary is not continuous with the tubal lumen?

• The abdominal ostium communicates with the peritoneal cavity
• The ovarian ligament contains a patent lumen
• The cervix opens into the infundibulum
• The ovary contains a duct opening into the ampulla

Q3. How are the fimbriae related to the mesosalpinx?

• They are folds within the ovarian cortex
• They form the uterosacral ligaments
• They are embedded in the uterine myometrium
• They occupy the free tubal end associated with the tube supported by the mesosalpinx

Q4. Which combination assists capture of the ovulated oocyte near the fimbrial end?

• Fimbrial mobility and ciliary activity
• Ureteric peristalsis
• Rectal contraction
• External urethral sphincter contraction

Q5. Which epithelium lines the mucosal surface of the fimbrial region?

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

Q6. Why is there no direct passage from ovarian tissue into the fimbrial lumen?

• The abdominal ostium is normally sealed
• The ovary and uterine tube lack direct luminal continuity
• The ovarian cortex is continuous with endometrium
• The ovary drains first into the cervix

Q7. Which arterial systems supply the lateral uterine tube near the fimbriae?

• Femoral and profunda femoris arteries
• Inferior epigastric and obturator arteries only
• Ovarian and uterine arterial branches
• Inferior mesenteric and superior rectal arteries

Q8. Which tubal segment lies medial to the fimbriae and is the usual site of fertilization?

• Cervical canal
• Vaginal fornix
• Ampulla
• Uterine part

Q9. What does the abdominal ostium connect?

• The cervix and peritoneal cavity
• The ovary and uterine cavity directly
• The tubal lumen and peritoneal cavity
• The tubal lumen and urinary bladder

Q10. Which description correctly relates the fimbriae to the infundibulum?

• They arise from the uterine fundus
• They project from the infundibular margin
• They attach the cervix to the sacrum
• They form the muscular wall of the ampulla
