Structure of Vertebrae
is the solid anterior part shaped like a cylinder, with the posterior surface flattened.
Body of the vertebra
Structure of Vertebrae
curved posterior part enclosing an opening.
Arch of the vertebra
Structure of Vertebrae: Arch of the vertebra
two short rounded processes that extend posteriorly, one from each lateral margin
of the dorsal surface of a vertebral body.
Pedicle
Structure of Vertebrae: Arch of the vertebra
two flattened plates of bone, one passing towards the midline from each pedicle.
Laminae
Structure of Vertebrae: Arch of the vertebra
two flattened plates of bone, one passing towards the midline from each pedicle.
Laminae
Structure of Vertebra: Arch of the vertebra
an opening formed by the vertebral arch with its pedicles and laminae, and the posterior surface of the vertebral body.
Vertebral foramen
Structure of Vertebra: Arch of the vertebra
is a tubular passage extending from the foramen magnum of the skull to the lower sacrum.
Vertebral canal
Structure of Vertebra: Arch of the vertebra
is formed by either the upper or lower curved surface of a pedicle
Vertebral notch
Structure of Vertebra: Seven processes
extend laterally from the junction of a pedicle with a lamina side
Transverse processes
Structure of Vertebra: Seven processes
extend up towards the head from the junction of each pedicle and lamina
Superior articular processes
Structure of Vertebra: Seven processes
projects caudally from the junction of each pedicle and lamina
Inferior articular process
