Q1. In a typical thoracic vertebra, how does the head of a rib usually articulate with adjacent vertebral bodies?
- Only with the vertebral body below
- Only with the spinous process
- Only with the transverse process
- With demifacets on two adjacent vertebral bodies
Q2. Which thoracic vertebra usually has a complete facet for the first rib and an inferior demifacet for the second rib?
- T12
- T1
- T10
- T6
Q3. How are the superior articular facets of typical thoracic vertebrae generally oriented?
- Posteriorly and slightly laterally
- Directly superiorly
- Inferiorly and anteriorly
- Anteriorly and medially only
Q4. How are the inferior articular facets of typical thoracic vertebrae generally oriented?
- Superiorly and posteriorly
- Posteriorly and laterally
- Anteriorly and slightly medially
- Directly inferiorly
Q5. Which movement is relatively favored by the orientation of typical thoracic zygapophysial joints?
- No movement
- Extensive flexion only
- Axial rotation
- Extensive extension only
Q6. What limits flexion and extension in the thoracic region compared with the cervical and lumbar regions?
- Rib cage, overlapping spinous processes, and facet orientation
- Fusion of all thoracic vertebrae
- Absence of intervertebral discs
- Presence of transverse foramina
Q7. Which thoracic vertebrae lack transverse costal facets for rib tubercles?
- T1 and T2
- T8 and T9
- T11 and T12
- T5 and T6
Q8. Why are T11 and T12 considered atypical thoracic vertebrae?
- They are fused to the sacrum
- They have complete body facets and lack transverse costal facets
- They contain transverse foramina
- They have no rib articulations
Q9. Which thoracic vertebra shows a transition toward lumbar-type inferior articular facets?
- T5
- T2
- T7
- T12
Q10. Why are thoracic pedicles important in defining the intervertebral foramina?
- They form costal cartilage
- Their vertebral notches help form intervertebral foramina
- They contain transverse foramina for vertebral arteries
- They attach directly to the sternum
