The human spine is made up of 24 movable bony segments called vertebrae. This vertebral column and the muscles attached to it support your entire upper body. These spinal bones also form a protective canal for your spinal cord. Your spinal cord is the continuation of your brain stem and is the main channel for the transmission of nerve impulses between your brain and your body. These nerve impulses carry vital information and messages from and to your brain. You can think of your brain as your body's central processing unit and your spinal cord as the main cable that connects all the body parts. Your brain is constantly producing vital messages that travel via electrical impulses to specific body parts to perform specific functions. Crucial life functions such as breathing, heartbeat, and digestion are dependent on these nerve impulses. Any interference with this process can result in a decrease in the function of that particular body part. This interference can be traced back to poor posture.

Posture is the window to your spine. Imbalances in your posture are outward signs of structural imbalances in your spine. Your posture is an indication of what kind of stresses your spine may be under. Postural or structural imbalances can cause premature deterioration of your spine and cause stress and irritation of your spinal cord and nerves. This can interfere with the transmission of your vital nerve impulses and can be related to a variety of symptoms and conditions.
