Question

Reason for calling sacrum as sacred bone ?

Answer 1

The word "sacrum", meaning "sacred" in Latin, lives on in English anatomy as the name for the large heavy bone at the base of the spine. The Romans called the bone the "os sacrum," which literally meant the "holy bone" and the Greeks termed it the "hieron osteon," the same thing, the "holy bone".

Answer 2

Answer:

Sacrum is a large bone formed by the fusion of five vertebrae. To it are articulated the hip bones on either side.
