Cervical Vertebra 3D

  • Atlas (C1)
    • * Is the first cervical vertebra, located at the top of the vertebral column.
    • * Supports the weight of the skull and allows for nodding of the head.
    • * Has no vertebral body and no spinous process.
    • * Has two lateral masses that articulate with the occipital condyles of the skull and the axis below. * Has transverse processes that are wide and flat, and house the vertebral artery.
    • * Has anterior and posterior arches that enclose the spinal cord. * Contains a large vertebral foramen that allows for the passage of the spinal cord and vertebral arteries.

 

  • Axis (C2)
    • * Is the second cervical vertebra, located immediately below the atlas, and allows for the rotation of the head.
    • * Has a strong, upward-projecting dens (odontoid process) that protrudes through the anterior portion of the atlas and forms a pivot joint with it.
    • * Has a vertebral body that is thicker and stronger than that of the atlas.
    • * Has short transverse processes that project laterally and attach to the levator scapulae muscle.
    • * Has a long, bifid spinous process that extends posteriorly and provides attachment for muscles and ligaments. * Contains a vertebral foramen that allows for the passage of the spinal cord.Regions of Vertebral Column.

 

  • Third to Sixth Cervical Vertebrae
    • * Are considered typical cervical vertebrae. * Have short bifid spinous processes.
    • * Possess transverse processes with anterior and posterior tubercles.
    • * Feature transverse foramina that provide passageways for the vertebral vessels.

 

  • Seventh Cervical Vertebra (C7)​​​​​​​
    • * Is also known as the vertebra prominens.
    • * Has a long spinous process that is nearly horizontal.
    • * Ends in a single tubercle (not bifid) and forms a visible protrusion.
    • * Supports the weight of the head.
    • * Provides attachment sites for the ligamentum nuchae, supraspinous ligaments, and numerous back muscles.
    • * Serves as an anchor point for the ligamentum nuchae, which runs from the occipital bone to the spinous processes of the cervical vertebrae.
