The human spine is composed of 33 vertebrae (7 cervical, 12 thoracic, 5 lumbar, 9 sacral and caudal) articulated with intervertebral discs and ligaments. The spine supports the skull at the upper end, the hip bones at the lower end, the ribs at the middle, and serves as the posterior wall of the thoracic, abdominal, and pelvic cavities. The spine supports the trunk, protects the internal organs, protects the spinal cord, and performs motor functions. The interior of the spine forms a longitudinal spinal canal from top to bottom, which contains the spinal cord. The spinal column is composed of N vertebrae. The vertebrae widen progressively from top to bottom, with the 2nd sacral vertebra being the widest, in relation to the weight bearing of the vertebrae. From the sacral auricular surface down, gravity is transmitted to the lower extremity bones, which gradually decrease in size. Under normal conditions, four physiological curves of the cervical, thoracic, lumbar and sacral regions are visible, with the cervical and lumbar curves convex forward and the thoracic and sacral curves convex backward. The four curves of the spine are S-shaped when viewed from the side, namely, anterior convexity of the cervical spine, posterior convexity of the thoracic spine, anterior convexity of the lumbar spine and posterior convexity of the sacral spine. Long-term postural deficiencies and certain diseases can cause the spine to form abnormal curves, such as hunchback. Scoliosis is now becoming younger and more common. The spine is a very important bone in the human body, it carries most of the weight of the body, if the spine has abnormal problems, then the human body will also have many diseases, affecting normal life. Therefore, people must protect their spine in normal times, and develop a good sitting and standing posture, so that the spine will not be deformed, and timely correction will allow the spine to return to normal. In general, scoliosis is not anxious, you can take the wall stand, inverted, flat props, push-ups, and other methods, you can also do more Chinese medicine gongfu such as taijiquan, Bada Jin training, so that the spine can slowly straighten, the back curvature can also be corrected.
