REGIONAL VERTEBRAE: CERVICAL VERTEBRAE (C3-C7)spinous process is usually short andBifid (C2-C6)Transverse foramenSup./ inf. Articular facetsalmost in transverse planeTriangular vertebral foramenConcave vertebral body that is wide• The body is wider laterally than in the anteroposteriordimension.• Except in C7, the spinous process is short, projects directly posteriorly, and is bifid, or forked (split at its tip)• The vertebral foramen is large and generally triangular.• Each transverse process contains a hole, a transverseforamen, through which the vertebral blood vesselspass.These vessels ascend and descend through the neck tohelp serve the brain.• The superior articular facets face superoposteriorly,whereas the inferior articular facets faceinferoanteriorly.Thus these articulations lie in an oblique plane, but, almost transversely oriented. Theorientation of these articulations allows the neck to carry outan extremely wide range of movements:flexion and extension, lateral flexion, and rotation.facetsaremorehorizontalsnidebkmorestackedandconcaveonlycervicalvertebraehavethis

The heads of the ribs articulate with these facets.The spinous process is long and points inferiorly.The vertebral foramen is circular.With the exception of T11 and T12, the transverse processes have facets that articulate with the tuberclesof the ribscalled transverse costal facetsThe superior and inferior articular facets, which join adjacent vertebrae, lie mainly in the frontal/ coronalplane. Such articulations limit flexion and extension, but they allow rotation between successive vertebrae.Transverse costal facetverygoodforrotationmargotianitate
REGIONAL VERTEBRAE: LUMBAR VERTEBRAE38The lumbar region of the vertebral column, the area commonly referred to as the small of the back, receives themoststress. The enhanced weight-bearing function of the five lumbar vertebrae (L1–L5) is reflected in theirsturdy structureTheir bodies are massive and appear kidney-shaped from a superior view.The pedicles and laminae are shorter and thicker than those of other vertebrae.The spinous processes are short, flat, and hatchet-shaped, and they project straight posteriorly and are quiterobust.
