Advanced Greater (False) Pelvis Quiz

Q1. Which sequence correctly traces the pelvic brim from posterior to anterior?

• Sacral hiatus, ischial tuberosity, obturator foramen, pubic arch
• Coccyx, ischial spine, acetabulum, iliac crest
• Iliac crest, acetabulum, ischial spine, coccyx
• Sacral promontory, sacral ala, arcuate line, pecten pubis, pubic crest

Q2. The arcuate line is located on which surface of the ilium?

• Acetabular surface
• Medial surface
• Lateral gluteal surface only
• Symphyseal surface

Q3. Which anatomical feature makes the greater pelvis relatively open anteriorly?

• Presence of the sacral hiatus
• Absence of a complete anterior bony wall
• Presence of the acetabulum
• Fusion of the ischial spines

Q4. Which statement best describes the functional relationship between the greater pelvis and abdomen?

• The greater pelvis contains only pelvic floor structures
• The greater pelvis supports lower abdominal viscera and is continuous with the abdominal cavity
• The greater pelvis forms the superior part of the thoracic cavity
• The greater pelvis is completely separated from the abdomen by bone

Q5. Which structure forms a muscular lining over much of the iliac fossa?

• Levator ani
• Iliacus
• Piriformis
• Coccygeus

Q6. Which anatomical boundary determines whether a structure is described as lying in the greater or lesser pelvis?

• Ischial tuberosity
• Pelvic brim
• Iliac crest
• Pelvic outlet

Q7. Why does the greater pelvis not form the principal bony birth canal?

• It lies superior to the pelvic inlet
• It is formed entirely by the coccyx
• It lies inferior to the pelvic outlet
• It contains no bony structures

Q8. Which change would directly alter the boundary between the greater and lesser pelvis?

• A fracture of the radius
• A change in the mandibular condyle
• A change in the configuration of the pelvic brim
• A change in the humeral head

Q9. Which description correctly relates the greater pelvis to the iliac fossae?

• The iliac fossae form substantial parts of the walls of the greater pelvis
• The iliac fossae are located within the obturator foramina
• The iliac fossae form the pelvic floor
• The iliac fossae form the posterior wall of the rectum

Q10. Which statement best integrates the anatomy of the greater pelvis?

• It is a closed bony cavity containing only reproductive organs
• It lies above the pelvic brim, is formed largely by the iliac wings, and supports lower abdominal viscera
• It lies below the pelvic outlet and forms the perineum
• It consists entirely of the sacrum and coccyx
