Transcript text: As the pelvis tilts posteriorly, the lumbar spine $\qquad$ and will present as a decreased $\qquad$ curve.
flex, lordotic
extend, lordotic
Solution
The answer is the first one: flex, lordotic.
Explanation:
When the pelvis tilts posteriorly, it causes the lumbar spine to flex. This is because a posterior pelvic tilt reduces the natural curve of the lumbar spine, leading to a more flattened appearance.
The lumbar spine normally has a lordotic curve, which is an inward curve. A posterior tilt decreases this lordotic curve, making it less pronounced.
Therefore, the lumbar spine will flex and present as a decreased lordotic curve.
