Intermediate Pubic Symphysis Quiz

Q1. Which tissue forms most of the interpubic disc?

• Adipose tissue
• Compact bone
• Fibrocartilage
• Elastic cartilage

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

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

Q3. Why is the pubic symphysis mechanically important?

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

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

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

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

• Insulin
• Relaxin
• Thyroxine
• Calcitonin

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?

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

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

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

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

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

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

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