Illustration showing a lumbar vertebra from a cranial perspective. In this superior view, the large, kidney-shaped vertebral body is seen anteriorly, characteristic of the lumbar region. The robust pedicles and laminae form the vertebral arch, enclosing the spacious spinal canal. The spinous process projects posteriorly from the centre of the arch, appearing short and broad in this perspective. Prominent transverse processes extend laterally, serving as attachment points for muscles and ligaments. The superior articular facets are clearly visible, oriented medially to articulate with the vertebra above. Cartilage is blue
