Q1. Which structures form the linea terminalis of the pelvis?
- Sacral promontory, arcuate line, pecten pubis, and pubic crest
- Iliac crest and ischial tuberosity only
- Acetabular rim and obturator foramen only
- Sacral hiatus and coccygeal cornua
Q2. Which structure forms the posterior boundary of the pelvic inlet?
- Ischial tuberosity
- Pubic arch
- Sacral promontory
- Anterior superior iliac spine
Q3. Which bony landmarks form the lateral boundaries of the pelvic outlet?
- Sacral alae
- Pubic tubercles
- Ischial tuberosities
- Anterior superior iliac spines
Q4. Which feature generally characterizes the female bony pelvis compared with the male bony pelvis?
- Broader subpubic angle
- Narrower subpubic angle
- Smaller pelvic outlet
- Longer and more curved sacrum in every case
Q5. Why is the ischial spine an important obstetric landmark?
- It forms the sacral promontory
- It is the main articulation with the femoral head
- It is used as a landmark for assessing fetal station
- It forms the anterior superior boundary of the pelvic inlet
Q6. At which structure do the ilium, ischium, and pubis meet during development?
- Obturator membrane
- Pubic symphysis
- Triradiate cartilage
- Sacral hiatus
Q7. How is weight from the vertebral column transferred through the bony pelvis during standing?
- From the ilium directly to the patella
- From the pubic symphysis directly to the vertebral bodies
- From the coccyx directly to the tibiae
- From the sacrum through the sacroiliac joints to the hip bones and femora
Q8. Which bony feature separates the greater sciatic notch from the lesser sciatic notch?
- Ischial spine
- Ischial tuberosity
- Pubic tubercle
- Iliac tubercle
Q9. Which feature of the sacrum articulates with the ilium to transmit forces across the posterior pelvic ring?
- Auricular surface
- Median sacral crest
- Sacral hiatus
- Anterior sacral foramen
Q10. Which statement best integrates the structural role of the pelvic bones?
- They consist only of the right and left femora
- They support pelvic contents, transmit loads, provide attachments, and form the bony framework of the pelvic cavity
- They form a rigid framework with no role in load transfer
- They function primarily to permit forearm rotation
