Parts of Typical Vertebrae 3D

  • Body of Vertebrae
    • * Is a cylindrical-shaped structure that is dense and strong, providing the primary weight-bearing support of the vertebra.
    • * is covered with a layer of cartilage and is typically wider from front to back than from side to side.
    • * The shape of the body varies depending on its position in the spine, and it has several bony processes that serve as attachment sites for muscles and ligaments.

 

  • Vertebral Arch
    • * Is a bony ring that extends from the body of the vertebra and surrounds and protects the spinal cord.
    • * Is composed of two main parts: the pedicles and the laminae.

 

  • Pedicles
    • * The pedicles are two short, thick bony structures that extend from the sides of the vertebral body and connect to the laminae.

 

  • Laminae​​​​​​​
    • * The laminae are two flat, thin bony plates that extend from the pedicles and join at the midline to form the posterior part of the vertebral arch.

 

  • Spinous Processes​​​​​​​
    • * The spinous process projects posteriorly from the junction of two laminae of the vertebral arch. * Is bifid in the cervical region, spine-like in the thoracic region, and oblong in the lumbar region.
    • * Serves as an attachment point for muscles and ligaments.

 

  • Transverse Processes​​​​​​​​​​​​​​
    • * The transverse processes project laterally on each side from the junction of the pedicle and the lamina and articulate with the tubercles of ribs 1 to 10 in the thoracic region.
    • * They also have transverse foramina in the cervical region and serve as attachment points for muscles and ligaments.

 

  • Articular Processes​​​​​​​
    • * The articular processes (facets) are two superior and two inferior projections from the junction of the laminae and pedicles.
    • * They articulate with other articular processes of the arch above or below, forming plane synovial joints.

 

 

  • Mamillary Processes​​​​​​​​​​​​​​
    • * The mamillary processes are tubercles on the superior articular processes of the lumbar vertebrae.
    • * The accessory processes project backward from the base of the transverse process and are lateral and inferior to the mamillary process of a lumbar vertebra.

 

  • Vertebral Foramina​​​​​​​​​​​​​​
    • * Are formed by the vertebral bodies and vertebral arches, specifically the pedicles and laminae.
    • * They collectively create the vertebral canal, which is responsible for transmitting the spinal cord with its meningeal coverings, nerve roots, and associated vessels.

 

  • Intervertebral Foramina​​​​​​​
    • * Are situated between the inferior and superior surfaces of the pedicles of adjacent vertebrae.
    • * Play a vital role in transmitting the spinal nerves and accompanying vessels as they exit the vertebral canal.

 

  • Intervertebral Foramina​​​​​​​
    • * Are present in the transverse processes of cervical vertebrae.
    • * Are responsible for transmitting the vertebral artery (excluding C7), vertebral veins, and autonomic nerves.
