Advanced Costovertebral Joints Quiz

Q1. A typical seventh rib articulates with which combination of vertebral structures at its head?

• T7 transverse process only
• T7 inferior demifacet and T8 superior demifacet only
• T6 inferior demifacet, T7 superior demifacet, and the T6 to T7 intervertebral disc
• T6 and T7 spinous processes

Q2. Which part of a typical rib head articulates with the vertebra immediately superior to the numerically corresponding vertebra?

• Inferior articular facet
• Superior articular facet
• Nonarticular part of the tubercle
• Costal groove

Q3. Which part of a typical rib head articulates with the numerically corresponding vertebral body?

• Costal groove
• Superior articular facet
• Angle of the rib
• Inferior articular facet

Q4. Why is an intra-articular ligament generally absent from a joint in which the rib head has only one articular facet?

• The joint contains no synovial membrane
• There is no typical crest separating two rib head facets for the ligament to attach to
• The rib does not articulate with a vertebra
• The radiate ligament replaces the entire joint capsule

Q5. Which statement correctly distinguishes the joint of the head of a rib from the costotransverse joint?

• The joint of the rib head is found only on ribs 11 and 12
• The costotransverse joint connects the rib directly to the sternum
• The rib head articulates with vertebral bodies, while the rib tubercle articulates with a transverse process
• Both joints are formed between the rib head and vertebral bodies

Q6. Why do ribs 11 and 12 have greater mobility at their posterior attachments than typical ribs?

• They attach directly to lumbar transverse processes
• They lack costotransverse joints and articulate with single vertebral bodies
• They are fused to their corresponding vertebrae
• They possess two costotransverse joints each

Q7. Which ligament would be most directly affected by disruption of the crest on the head of a typical rib?

• Intra-articular ligament of the head of the rib
• Lateral costotransverse ligament
• Ligamentum flavum
• Superior costotransverse ligament

Q8. During inspiration, coordinated movement at the costovertebral and costotransverse joints of the upper ribs primarily increases which thoracic dimension?

• Transverse diameter only
• Anteroposterior diameter
• Width of the intervertebral foramina only
• Diameter of the vertebral canal

Q9. A lesion involving the superior costal demifacet of T8 would most directly interfere with articulation of which rib?

• Tenth rib
• Eighth rib
• Seventh rib
• Ninth rib

Q10. Which description best summarizes the costovertebral joints?

• Synovial joints located only between ribs 11 and 12 and the lumbar vertebrae
• Synovial joints between rib heads and thoracic vertebral bodies that stabilize the ribs while permitting respiratory movement
• Fibrous joints connecting rib tubercles exclusively to transverse processes
• Cartilaginous joints connecting the ribs directly to the sternum
