Procedures1 chap 9 Lumbar, sacrum, coccyx
| Question | Answer |
|---|---|
| Intervertable foramen are at what degree to the midsagittal plane? | 90 |
| _______ are spaces or opening between two pedicles when two vertebrae are stacked ontop of one another. (superior and inferior vertebral notches) | intervertebral foramen |
| Where are the superior vertebral notches located? | along the upper surface of each pedicle |
| From the junction of the pedicles and laminae, the process that projects upward? and downward? | upward is superior art process, downward is inferior |
| the term Facet is interchangeable with what? | zygapophyseal joint |
| Zyga joints form what angle in lumbar? | 30-50. Upper/proximal is 50, lower/distal is 30. |
| Laminae form a bridge between... | transverse processes, lateral masses, and spinous process. |
| Portion of each lamina between the superior and inferior articular processes is the ____. | Pars interarticularis |
| Pars interarticularis is visualized in what position? | Oblique. |
| the apex of the sacrum is pointed _____ and _____. | inferiorly and anteriorly |
| _____ sets of ____________ transmit nerves and blood vessels. | four sets of pelvic sacral foramina |
| What of the sacrum forms the zygapophyseal joints with the inferior articular processes of the 5th L vert? | the two superior articular processes |
| Promontory of the sacrum is? | Anterior ridge of the body of the first sacral segment. Forms the posterior wall of the inlet of the true pelvis |
| Continuation of the vertebral canal that contains sacral nerves? | Sacral canal |
| This is formed by fused spinous process of the sacral vertebrae? | Median sacral crest |
| The sacrum articulates with the ilium at the _____, to form the SI joint. | auricular surface |
| small tubercles that project inferiorly from each side of the fifth sacral segment? Articulate with what of the coccyx? | Sacral horns, horns of the coccyx. |
| Each SI joint opens obliquely at an angle of ____ | 30 degrees, posteriorly |
| Scottie dog. Neck? Ear? Eye? Nose? Front legs? | Neck= 1 pars interarticularis Ear= 1 superior art. process Eye= 1 pedicle Nose= 1 transverse process Front legs= 1 inferior art. process |
| Zyga joints classifications and mobility type? | Synovial, diarthrodial, plane/gliding. (all of spine) |
| Intervertebral joints classifications and mobility type? | Cartilaginous, amphiarthrodial. |
| Zyga, downside visualized when? | Posterior oblique |
| Zyga upside is visualized when? | Anterior. |
| 50 degree oblique for special focus on what vertebras? | L1 & 2 |
| what forms the posterior wall of the inlet of the true pelvis? | Promontory |
| where is the sacral canal? | posterior to the body of the first sacral segment |
| articulating facets of the superior articular processes of the sacrum open to the ___. | rear |
| If interest is specifically for L1 or L2, what degree of rotation should be used? | at least 50 degrees. (because the upper verts take on some characteristics of T-spine, which are at 70 degrees) |
| ASIS is at what level? | S1-S2 |
| Lower costal margin is at what level? | L2-L3 |
