Verified step by step guidance

Understand the anatomy of a typical lumbar vertebra: Lumbar vertebrae are located in the lower back and are designed to support the weight of the upper body. They are distinct from other vertebrae in the spine due to their structural features.

Review the characteristic features of lumbar vertebrae: Lumbar vertebrae typically have large, kidney-shaped bodies to provide stability and support for the weight-bearing function. This is a key distinguishing feature.

Compare lumbar vertebrae to other types of vertebrae: Unlike thoracic vertebrae, lumbar vertebrae do not have costal facets for rib articulation. Costal facets are specific to thoracic vertebrae, which connect to the ribs.

Examine the spinous process: Lumbar vertebrae have a broad and blunt spinous process, not a bifid spinous process. A bifid spinous process is characteristic of cervical vertebrae.

Check for transverse foramina: Lumbar vertebrae lack transverse foramina, which are openings found in cervical vertebrae to allow passage of the vertebral arteries. This absence is another distinguishing feature of lumbar vertebrae.
