The umbilicus is located opposite which intervertebral disc level?

Explanation:
Landmarks on the abdomen align with underlying vertebral levels, though not perfectly. The umbilicus sits roughly opposite the L3–L4 intervertebral disc in an average adult. This happens because the spinal cord ends around L1–L2, so the lumbar spine sits closer to the skin, placing the disc between L3 and L4 directly beneath the umbilicus. This relationship is a standard reference used in anatomy for locating abdominal structures and planning procedures.
