The spine, or the backbone, is the bony connection between the skull and the pelvic bone. It not only helps us stand upright, but it also acts like a superhighway connecting the brain to the rest of our body. It can be divided into upper (cervical), middle (thoracic), lower (lumbar) spine, sacrum and coccyx (tailbone).
The spinal cord, connecting the brain to rest of the body, passes through this superhighway like a cable. When it reaches the lower spine, it fans out like spaghetti to form the cauda equina (Latin: Equina- Horse, Cauda-Tail “Horse’s Tail”)
