Sacral
1. Pertaining to the sacrum, a large bone in the lower part of the spine that is shaped like a triangle. The sacrum consists of five vertebrae (bones that form an opening in which the spinal cord passes), known as S1 through S5.

2. Pertaining to one of the five nerves that are emerge (come out of) the area of the sacrum. These nerves are known as sacral nerves.

Sacral comes from the Latin word "sacer" meaning "sacred." This is because the sacrum was considered a sacred (highly valued; holy) bone. Specifically, it was believed that the sacrum could not be destroyed and that it was the part of the body that would allow someone to rise from the dead.
