Vertebrae Quiz
Questions: 16 · 10 minutes
1. A specimen has a small body, uncinate processes, transverse foramina, and a large triangular vertebral foramen. How should it be classified?
As a typical cervical vertebra
As a mid-thoracic vertebra
As a sacral segment
As a lumbar vertebra
2. During examination of the posterior sacrum, an inferior opening is seen between the sacral cornua. What is this opening?
Sacral canal
Anterior sacral foramen
Intervertebral foramen
Sacral hiatus
3. An isolated vertebra has a massive body, a short hatchet-shaped spinous process, and mammillary processes. Which identification best fits?
Lumbar vertebra
Typical cervical vertebra
Mid-thoracic vertebra
Coccygeal vertebra
4. A small terminal bone made of usually fused rudimentary vertebrae articulates superiorly with the apex of the sacrum. What is it?
Atlas
Coccyx
Axis
Fifth lumbar vertebra
5. Which statement correctly describes the atlas, C1?
It bears the dens that projects superiorly toward the skull
It has a large body with costal facets for the first rib
It is a ring-like vertebra whose superior facets receive the occipital condyles
It forms the lumbosacral angle through articulation with L5
6. The dens, which serves as a pivot for rotation of the atlas and head, belongs to which vertebra?
C2
C7
T1
C1
7. On which part of the sacrum is the sacral promontory located?
The posterior surface of the sacral apex
The lateral edge of the sacral hiatus
The projecting anterior margin of the S1 body
The median sacral crest at S3
8. Where does a typical rib articulate with a mid-thoracic vertebra?
At the spinous process and inferior articular process
At the vertebral foramen and superior vertebral notch
At costal facets on the vertebral body and a transverse costal facet
At the lamina and mammillary process
9. Which finding best supports identifying a vertebra as T11 or T12 rather than a typical mid-thoracic vertebra?
A bifid spinous process and transverse foramina
A complete costal facet on the body and no transverse costal facet
Superior and inferior demifacets plus a transverse costal facet
A kidney-shaped body with prominent mammillary processes
10. Which combination is most characteristic of a typical cervical vertebra from C3 to C6?
Transverse foramina, a relatively small body, and often a bifid spinous process
Costal facets, a heart-shaped body, and a long inferiorly angled spinous process
A large kidney-shaped body, mammillary processes, and no transverse foramina
Fused bodies, anterior sacral foramina, and a median crest
11. Which description best matches a typical lumbar vertebra?
Small body, transverse foramina, and a commonly bifid spinous process
Heart-shaped body, costal facets, and a long downward-projecting spinous process
Ring-shaped structure without a body or true spinous process
Large kidney-shaped body with a short, broad spinous process
12. A vertebra bears facets for rib attachment and has a relatively circular vertebral foramen. Which regional identification is most appropriate?
Typical cervical vertebra
Typical thoracic vertebra
Typical lumbar vertebra
Coccygeal vertebra
13. An isolated vertebra has transverse foramina and a bifid spinous process. From which region is it most likely derived?
Thoracic region
Cervical region
Lumbar region
Sacral region
14. Which feature is absent from the atlas under normal anatomy?
Superior articular facets
Anterior and posterior arches
Transverse foramina
A vertebral body and true spinous process
15. A defect is located in the bridge of bone between the superior and inferior articular processes of a lumbar vertebra. Which structure is involved?
Pedicle
Lamina
Pars interarticularis
Transverse process
16. Which feature most directly distinguishes a typical cervical vertebra from a typical thoracic vertebra?
A spinous process projecting from the vertebral arch
Superior and inferior articular processes
Pedicles connecting the body to the vertebral arch
A transverse foramen within each transverse process
