Position in the trunk

L1 begins the five-vertebra lumbar region, immediately below T12.

Sources: OpenStax

Orient the surface

Lumbar vertebral bodies are relatively large, reflecting their load-bearing role. They do not have the rib facets characteristic of thoracic vertebrae.

The named features are orientation cues, not separately labeled selectable objects. Surface resolution limits what can be distinguished.

Sources: OpenStax

Compare in context

Compare L1 with T12 above and L2 below. Rotate the view to inspect the bone surface; the gaps contain no modeled discs.

Show context restores the available trunk bones and both psoas and external oblique muscles. It does not reconstruct soft tissues or demonstrate joint movement.

Read the model

Explore lumbar vertebra l1 in 3D

  1. Inspect the isolated bone. Rotate the surface, then use Focus selection if it is too small.
  2. Restore its neighbors. Compare L1 with T12 above and L2 below. Rotate the view to inspect the bone surface; the gaps contain no modeled discs.
  3. Return to the trunk. Use the hierarchy below the model to move back to the overview. Trunk study →

About this model

BodyParts3D identifies this surface as lumbar vertebra l1: FMA13072 / FJ3157. Its original coordinates and topology are preserved. This is a midline structure, not a left or right counterpart.

The trunk assembly includes thoracic and lumbar vertebrae, sacrum, ribs, sternum parts, hip bones, both psoas and external oblique muscles. Discs, costal cartilages, cervical vertebrae, coccyx, organs and other trunk muscles are not loaded.
