Advanced Costal Facets Quiz

Q1. Which structures participate in the typical articulation of the head of rib 7?

• T7 and T8 only
• T6, T7, and the T6-T7 intervertebral disc
• T7 transverse process only
• T5, T6, and the T5-T6 intervertebral disc

Q2. Why can the head of a typical rib articulate with two adjacent vertebral bodies?

• Its tubercle articulates with two vertebral bodies
• Its head has two articular facets that correspond to adjacent vertebral demifacets
• Its costal cartilage attaches to two vertebrae
• Its shaft crosses two intervertebral foramina

Q3. Which structure is associated with the crest on the head of a typical rib between its two articular facets?

• Ligamentum flavum
• Intra-articular ligament of the head of the rib
• Supraspinous ligament
• Interspinous ligament

Q4. Which vertebra typically has a single complete costal facet for rib 11 rather than superior and inferior demifacets?

• T3
• T6
• T8
• T11

Q5. Which statement most accurately describes the costal facet pattern of T10?

• It articulates only with the tubercle of rib 9
• It never has a costal facet
• It has a complete facet for rib 12
• It commonly has a single complete facet for rib 10, with variation possible

Q6. Which vertebrae normally have body costal facets but no transverse costal facets?

• T8 and T9
• T11 and T12
• T1 and T2
• T5 and T6

Q7. How do costal facets contribute to respiratory movement?

• They attach the diaphragm directly to the vertebral bodies
• They prevent all rotation of the ribs
• They rigidly fuse every rib to the vertebral column
• They form articulations that permit controlled movement of the ribs

Q8. Which articulation allows the tubercle of rib 5 to move against the thoracic vertebral column?

• Joint of the rib head with T4 only
• Costotransverse joint with T5
• Sternocostal joint with T5
• Interchondral joint with T6

Q9. A vertebra with one complete body costal facet and no transverse costal facet is most consistent with which levels?

• T5 or T6
• T7 or T8
• T11 or T12
• T3 or T4

Q10. Which description best summarizes the costal facets of thoracic vertebrae?

• Articular surfaces connecting thoracic vertebrae directly to the sternum
• Openings that transmit intercostal nerves through vertebral bodies
• Ligament attachment sites found only on thoracic spinous processes
• Articular surfaces on thoracic vertebrae specialized for articulation with rib heads and tubercles
