vertebral foramen | hole in the right of the vertebra that allows passage for the spinal cord |
vertebral notches | the concave superior and inferior surfaces of the pedicles |
intervertebral foramina | the spaces formed by joining with the vertebral notches above and below which allows passage of spinal nerves and blood vessels |
zygapophyseal joints | the process that extends from the verteral that form gliding (diarthroidal) joint |
nucleus pulposis | soft and pulpy center of the intervertebral disks |

articular pillar | the bones of the articular process for a column |
transverse foramen | a hole in the transverse process that form a passage way for artery and veins |
costal/costoertebra joints | joint that are formed by the facets that articulate with the ribs |
pars interarticularis | the narrow segment of bone between the superior and inferior articular processes |
