What are the structures forming the bed of the sciatic nerve?
A combination of 5 nerve roots that exit from inside the lower lumbar and upper sacral spine—L4, L5, S1, S2, and S3—forms the sciatic nerve. These 5 nerves group together deep in the buttock, near the front surface of the piriformis muscle, and combine to form the single large, thick sciatic nerve.

What are the nerves of the abdomen lower back and pelvis?
Nerves of the Abdomen, Lower Back and Pelvis. The nervous system of the abdomen, lower back, and pelvis contains many important nerve conduits that service this region of the body as well as the lower limbs.
