The sacral nerves are the five pairs of spinal nerves which exit the sacrum at the lower end of the vertebral column. The roots of these nerves begin inside the vertebral column at the level of the L1 vertebra, where the cauda equina begins, and then descend into the sacrum.
The sciatic nerve is the longest and largest nerve in the body; it measures three-quarters of an inch in diameter. It originates in the sacral plexus; a network of nerves in the low back (lumbosacral spine). The lumbosacral spine refers to the lumbar spine and the sacrum combined.he sciatic nerve starts in your low back, which is called your lumbar spine. The nerve roots are at the L4 and L5 vertebrae (the 'L' means lumbar, and the numbers indicate the level of the vertebraâwhere it is in your back). The sciatic nerve also travels through your pelvic region (sacrum).
