| Question | Answer |
|---|---|
| Vertebral arch | posterior ring like portion |
| Vertebral foramen | the space enclosed by the vertebral arch and body |
| What forms the vertebral arch? | two pedicles and two lamina |
| Vertebral notch | the concave superior and inferior surfaces of the pedicles |
| Intervertebral foramina | formed by the vertebral notches of a superior and inferior vertebrae |
| Laminae (L-spine) | thick, project posteriorly from the pedicles running from the transverse process to the spinous process. |
| Superior and inferior articular processes | arise from the junction of the pedicle and lamina to articulate with the vertebrae above and below |
| The superior articular process has a facet where? | on the posterior surface |
| The inferior articular process has a facet where? | on the anterior surface |
| Zygapophyseal joint | the articulation between the superior and inferior articular facet |
| The transverse processes of L1-L3 are directed: | laterally |
| The transverse processes of L4-L5 are directed: | superiorly |
| The pedicles are directed: | posteriorly |
| Pars interarticularis | portion of the lamina located between the superior and inferior articular process |
| Mamillary process | smooth rounded process on the back of each superior articular process |
| Accessory process | near the point of attachment on the transverse process, posteriorly |
| How do the zygapophyseal joints lie to the MSP? | 30-60 degrees |
| How do the intervertebral foramina lie to the MSP? | perpendicular |
| the ear of the scotty dog represents what? | the superior articular process |
| the nose of the scotty dog represents what? | transverse process |
| the eye of the scotty dog represents what? | pedicle |
| the neck of the scotty dog represents what? | pars interarticuaris |
| the body of the scotty dog represents what? | lamina |
| the foot of the scotty dog represents what? | inferior articular process |
| intervertebral joint space type | cartilaginous symphysis |
| zygapophyseal joint space type | synovial gliding |
| sacroiliac joint type | irregular gliding |
