Which vertebrae are bifurcated

Cervical Spine 1. Body 2. Transverse foramen: they allow for passage of vertebral arteries and veins to and from the brain.

Superior articular process: 4. Bifurcated spinous process: the spinous processes of the cervical spine are bifurcated double tip with the exception of the first and seventh vertebrae.

Lamina 6. Pedicle 7. Transverse foramen The first cervical vertebrae C-1 is known as the atlas. Thoracic Spine The spinous processes of thoracic vertebrae are long and slender, and project sharply downward.

Facets and demifacets are surfaces where ribs attach to all of the vertebral bodies except the 11th and 12th. This lateral sagittal MRI image of the thoracic spine shows a mass at the level of T It is pressing against the spinal cord. Transverse process.

Vertebral neural spine bifurcation has been historically treated as largely restrictive to sauropodomorph dinosaurs; wherein it is inferred to be an adaptation in response to the increasing weight from the horizontally extended cervical column.

Because no extant terrestrial vertebrates have massive, horizontally extended necks, extant forms with large cranial masses were examined for the presence of neural spine bifurcation. Here, I report for the first time on the soft tissue surrounding neural spine bifurcation in a terrestrial quadruped through the dissection of three Ankole-Watusi cattle.
