The umbilicus aligns with which intervertebral disc level?

Explanation:
The umbilicus sits in the midline over the abdominal wall at roughly the L3–L4 intervertebral disc level. In most adults, this landmark corresponds to the disc space between the third and fourth lumbar vertebrae. This relationship helps clinicians relate surface landmarks to underlying vertebral anatomy, especially since lower landmarks like the iliac crests align with L4–L5 and are lower than the navel. While there is some individual variation, the standard teaching is that the umbilicus aligns with the L3–L4 disc.
