What Is the Spinal Cord?
The spinal cord is a long bundle of nerve tissue that carries messages between the brain and the rest of the body. It runs inside the spinal canal and connects with spinal nerves. The spinal cord helps control movement, sensation, and many automatic body functions through ongoing nerve communication.

Key Takeaways About Spinal Cord
- It is nerve tissue, not a bone or spinal disc.
- The spinal canal surrounds and protects the cord.
- The spinal cord is different from the sciatic nerve.
How Spinal Cord Works
Spinal cord tissue carries electrical and chemical messages along pathways inside the spinal canal. Sensory signals travel toward the brain, while movement commands travel toward muscles. The cord also supports nerve activity that helps regulate automatic functions.

The spinal column surrounds the cord with vertebrae, discs, joints, and supporting tissues. This arrangement creates a protected passage while allowing the back to move. Spinal decompression therapy focuses on changing mechanical loading around the spine, so a provider considers the cord's location and nearby nerve structures during care.
From the Arrowhead Clinic Chiropractor Garden City team
When we discuss spinal decompression therapy, we review the spine's structure and the location of the spinal cord in relation to the treatment area. Our team also considers nearby nerve roots, discs, and vertebrae so the service remains focused on the relevant spinal region.

A person receiving spinal decompression therapy may have symptoms linked to a lower back condition. The care plan addresses the targeted spinal region while recognizing that the spinal cord and nearby nerve structures have different locations and functions.
