Q1. Which sequence correctly traces the pelvic brim from posterior to anterior?
- Sacral hiatus, ischial tuberosity, obturator foramen, iliac crest
- Iliac crest, acetabulum, ischial spine, coccyx
- Coccyx, ischial spine, acetabulum, iliac crest
- Sacral promontory, sacral ala, arcuate line, pecten pubis, pubic crest
Q2. Which pelvic diameter extends from the sacral promontory to the superior border of the pubic symphysis?
- Interspinous diameter
- Intertuberous diameter
- Oblique diameter
- Anatomical conjugate
Q3. Which pelvic measurement extends from the sacral promontory to the inferior border of the pubic symphysis?
- Interspinous diameter
- Transverse diameter of the outlet
- Diagonal conjugate
- Intertuberous diameter
Q4. Which diameter represents the narrow transverse dimension of the midpelvis between the ischial spines?
- Interspinous diameter
- External conjugate
- Diagonal conjugate
- Anatomical conjugate
Q5. Which diameter of the pelvic outlet is measured between the inner aspects of the ischial tuberosities?
- Diagonal conjugate
- Interspinous diameter
- Intertuberous diameter
- Anatomical conjugate
Q6. Why are the ischial spines clinically important during labor?
- They articulate directly with the sacral promontory
- They define the superior boundary of the greater pelvis
- They provide reference landmarks for fetal station
- They form the acetabular roof
Q7. Which characteristic generally increases the dimensions of the female lesser pelvis compared with the male lesser pelvis?
- More medially projecting ischial spines
- Broader pelvic cavity and wider outlet
- Narrower subpubic angle
- Smaller transverse dimensions
Q8. Which structure forms the posterior boundary of the pelvic outlet?
- Sacral promontory
- Pubic symphysis
- Tip of the coccyx
- Anterior superior iliac spine
Q9. Why can posterior movement of the coccyx increase the functional size of the pelvic outlet?
- It moves the sacral promontory anteriorly
- It increases the anteroposterior diameter of the outlet
- It closes the pubic arch
- It decreases the transverse diameter of the inlet
Q10. Which statement best integrates the anatomical significance of the lesser pelvis?
- It lies above the pelvic brim and contains only abdominal viscera
- It lies between the pelvic inlet and outlet, contains pelvic viscera, and forms the principal bony framework of the birth canal
- It is formed entirely by the iliac fossae
- It has no relationship to the pelvic floor or pelvic viscera
