The bundle of spinal nerve roots that descend past the L1 vertebra is called the cauda equina.

Here are the steps to understand this:

1. The human spine is divided into several sections: cervical, thoracic, lumbar, sacral, and coccyx, from top to bottom. The L1 vertebra is in the lumbar section.

2. The spinal cord extends from the brain down to about the L1 vertebra. Below this level, the spinal cord ends.

3. However, there are still nerves that need to reach the lower parts of the body. These nerves descend from the end of the spinal cord in a bundle.

4. This bundle of nerves looks a bit like a horse's tail, so it was named the "cauda equina", which is Latin for "horse's tail".
