: projects posteriorly to transverse process.
: continues from pedicle. Both lamina meet to from the arch.
Processses associated with typical vertebra?
: singular process that projects from dorsal aspect
: projects laterally from junction at pedicle and lamina. Sites for muscle attachments.
Superior articular process
: has facet that allows articulation with superior vertebrae.
Inferiour articular process
: inferior and posterior to Superior articular process. Articulates with inferior vertebrae.
: openings in C1-C6/C7 that allow verterbral arteries to the brain.
spinous process C2-C6
C1 or Atlas
Not true vertebrae level.
Superior articular facets articulate with the
to form the
C2 or Axis
Dens or odontoid process
: unique process projecting in a vertical plain superirorly. Articulates with the atlas allowing for circumferencial movements.
12 thoracic vertebrae
Superior costal facets
: superior dorsal aspect of vertebral bodies.
Inferiror costal facets
: inferior dorsal aspect of vertebral bodies.
Transvers costal facets
: lateral most aspects of transverse processes.
Blunt or rounded
5 fused segments of bone
: superior lateral aspect of sacrum. Articulate with the
aricular surface of the ilium
Medial sacral crest
: ridge in the midline on the dorsal surface. Fusion of spinous process S1-S5.
Posterior sacral foramina
: lateral on both sides of the medial sacral crest. Allow passage of spinal nerves.
Superior articular processes of the sacrum
: articulate witht the inferior articular process of the 5th lumber.
