Sacr-

The sacrum is a structural element of bones that is distinguished by its special connection with other bones of the human skeleton, namely the sacrum. This concept means their anatomical structure and location. The main function of the location of the sacrum is to protect the organs of the lower pelvis, pelvis and coccygeal region from mechanical damage and damage due to the ability to provide protection to such organs. The sacrum is located in the lower part of the spine, in the lumbar region. The upper parts of the three processes of the sacral vertebrae and the pelvis are attached to these areas.
