Notice that when two lumbar vertebrae are put together little to no lateral rotation is allowed because of the shape of the articulating bones. Why do you think they interact in this manner?

The limited lateral rotation between lumbar vertebrae is primarily due to their structural design, which features interlocking facets and a larger, more robust vertebral body that prioritizes stability and weight-bearing. The orientation of the facet joints in the lumbar region is primarily sagittal, allowing for flexion and extension while restricting rotational movements. This anatomical arrangement helps protect the spinal cord and maintain overall spinal stability during activities that involve lifting or twisting, reducing the risk of injury.
