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 sacrum forms joints with each of the hip bones and helps to stabilize the
pelvis.
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. As a result, some of the problems that may occur as a result of
subluxations here could be sacroiliac conditions, hemorrhoids, scoliosis, and
pain when sitting.
