Intermediate Pubic Symphysis Quiz

Q1. Which tissue forms most of the interpubic disc?

• Fibrocartilage
• Adipose tissue
• Compact bone
• Elastic cartilage

Q2. What is another name for the inferior pubic ligament?

• Anterior longitudinal ligament
• Interspinous ligament
• Iliofemoral ligament
• Arcuate pubic ligament

Q3. Why is the pubic symphysis mechanically important?

• It forms the posterior wall of the acetabulum
• It completes and stabilizes the anterior pelvic ring
• It creates the greater sciatic foramen
• It directly supports the lumbar discs

Q4. Which description best characterizes movement at the pubic symphysis?

• It behaves like a ball and socket joint
• It permits unrestricted circumduction
• Small translations and slight separation can occur
• It permits only axial rotation through 90 degrees

Q5. Which hormone is associated with increased pelvic ligamentous laxity during pregnancy?

• Thyroxine
• Insulin
• Calcitonin
• Relaxin

Q6. What happens to pubic symphyseal mobility during pregnancy?

• It loses its interpubic disc
• It always becomes completely fused
• It becomes a freely mobile synovial joint
• It can increase

Q7. Which structure helps resist separation of the pubic bones inferiorly?

• Transverse acetabular ligament
• Inferior pubic ligament
• Nuchal ligament
• Anterior cruciate ligament

Q8. The pubic symphysis is part of which larger mechanical structure?

• Cranial vault
• Pelvic ring
• Shoulder girdle
• Thoracic cage

Q9. Why is the interpubic disc suited to the pubic symphysis?

• It permits unrestricted axial rotation
• It functions as a growth plate throughout life
• It produces synovial fluid for wide movement
• Fibrocartilage resists compression and tensile stress

Q10. Which statement best distinguishes the pubic symphysis from a typical synovial joint?

• It is united by fibrocartilage and lacks a typical synovial joint cavity
• It contains no cartilage
• It is held together only by skeletal muscle
• It has a large synovial cavity and articular menisci
