👉 Craniosacral is a medical term that refers to the intervertebral discs between vertebrae, which are located at the base of the spine. These discs are responsible for supporting and cushioning the spinal cord and other organs in the body. The craniosacral system is composed of two main components: the vertebral column (the backbone) and its surrounding soft tissues. The vertebral column consists of 24 vertebrae, each with a different shape and size.
