They are found in almost all vertebrae (except the 1st and 2nd cervical vertebrae) and serve as a means of differentiating them from the other bones of the skeleton.
All vertebrae have 7 Basic Elements:
1. Body: It is most of the vertebra. It is single and medium and facing forward. It is represented by a cylinder segment, with an upper and lower face.
2. Spiny Process: It is the part of the bony arch that lies medially and posteriorly.
3. Transverse Process: There are 2 lateral extensions, right and left, that project transversely on each side of the point of union of the pedicle with the blade.
4. Articular Processes: There are four, two superior and two inferior. These protrusions are designed to articulate the vertebrae with each other.
5. Blades: There are two blades, one right and one left, which connect the spinous process to the transverse process.
6. PediclesThey are narrower parts that connect the transverse process to the vertebral body.
7. Vertebral foramen: Located posterior to the body and limited laterally and posteriorly by the bony arch.
