Take time to learn about the relationship between the three systems and the role each plays in the health of your back. The bones and joints of the skeletal system make up the basic support structure of your body. The spine is the primary element of your skeletal system. Your central nervous system consists of your brain and spinal cord. The nerves that connect your spinal cord to your muscles, joints and skin are part of the peripheral nervous system .
Messages travel to and from the brain and muscles in split seconds.
Your Soft Tissue System Muscles, ligaments, and tendons are connective tissue that stabilize bones and joints and allow movement. Your muscles contract to move bones and joints and control all your movements. They do not work individually, but in muscle groups. Your ligaments are the connections between bones. They provide strength and allow some movement.
