Getting an accurate diagnosis of the cause of back pain is critical, because different diagnoses will require very different treatment approaches. Coccyx region- the four fused bones of the coccyx or tailbone provide attachment for ligaments and muscles of the pelvic floor.There are five sacral vertebrae, which are fused together. Sacrum- the main function of the sacrum is to connect the spine to the hip bones (iliac).The five lumbar vertebrae are numbered L1 to L5. Lumbar (low back)- the main function of the lumbar spine is to bear the weight of the body.The twelve thoracic vertebrae are numbered T1 to T12. Thoracic (mid back)– the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs.The seven cervical vertebrae are numbered C1 to C7. Cervical (neck)- the main function of the cervical spine is to support the weight of the head (about 10 pounds).The curves work like a coiled spring to absorb shock, maintain balance, and allow range of motion throughout the spinal column. The neck (cervical) and low back (lumbar) regions have a slight concave curve (Lordosis), and the thoracic and sacral regions have a gentle convex curve (Kyphosis). When viewed from the side, an adult spine has a natural S-shaped curve. Protected deep inside the vertebrae, the spinal cord connects your body to the brain, allowing movement of your arms and legs. The spinal column provides the main support for your body, allowing you to stand upright, bend, and twist. Ligaments and muscles connect the vertebrae together and keep them aligned. The spine is made of 33 individual bones (vertebra) stacked one on top of the other with 25 articulating joints.
