The vertebral pedicle is often used as a radiographic marker and entry point in vertebroplasty, kyphoplasty, and spinal fusion procedures. The arcuate foramen is a common anatomical variation more frequently seen in females. It is a bony bridge found on the first cervical vertebra, the atlas where it covers the groove for the vertebral artery. [22]
In the transverse plane, it lies between the lamina and pedicle. In other words, in the axial view, it is the bony mass between the facets that is anterior to the lamina and posterior to the pedicle. It is abnormal in spondylolysis, either due to fracture or congenitally. [1] Bilateral C2 pars fractures are known as a variant of the hangman's ...

In the upper lumbar region the lamina are taller than wide, but in the lower lumbar vertebra the lamina are wider than tall. The lamina connects the spinous process to the pedicles. The vertebral foramen within the arch is triangular, larger than the thoracic vertebrae , but smaller than in the cervical vertebrae .
The superior and inferior articular processes of cervical vertebrae have fused on either or both sides to form articular pillars, columns of bone that project laterally from the junction of the pedicle and lamina. The articular facets are flat and of an oval form: the superior face backward, upward, and slightly medially.
The articular process or zygapophysis (Greek: ζυγόν, romanized: zugón, lit. 'yoke' + apophysis) of a vertebra is a projection of the vertebra that serves the purpose of fitting with an adjacent vertebra.
Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures; Pedicle of a skin flap (medicine) Hilum of kidney, also called the renal pedicle; Pedicel, a foot process of a some cells
The tenth thoracic vertebra has an entire articular facet (not demi-facet) on either side, which is placed partly on the lateral surface of the pedicle. It doesn't have any kind of facet below, because the following ribs only have one facet on their heads. The thoracic spinal nerve 10 (T10) passes inferior to it.
