The Sacrum and Coccyx
The sacrum and coccyx are
commonly referred to as your "base bone" or "tail bone". As a child the sacrum
consists of five individual bones and the coccyx is made up of three to five
bones. In the adult, the sacral segments and the coccygeal segments fuse so that
each of these two bones are solid singular bones.
The nerves that exit the sacrum and coccyx go to the tissues and organs in that area. These include the muscles of the buttocks and hips as well as portions of the thigh and leg. In addition, organs and tissues
such as the rectum and portions of pelvic tissues are also innervated by these
nerves.
