The vertebrae are the common name for the vertebrae, which are the central bones, located between the skull and the lower limbs, playing the role of intermediate bridge, connected by ligaments, joints and intervertebral discs. In terms of anatomy, the vertebrae include the cervical, thoracic, lumbar, and sacrococcygeal bones, and the number of vertebrae is 32-33 in infants at birth and 26 in adults.1. Cervical vertebrae: usually composed of seven vertebrae, the first two sections are connected to the skull and constitute the craniocervical junction area. In terms of anatomy, the vertebrae are not identical to the following cervical vertebrae segments 3-7. Cervical vertebrae section 3-7 is the structure of the lower cervical vertebrae, this part is subject to more violence of flexion and extension and torsion, so the external forces in life can easily lead to injury of the lower cervical vertebrae; 2, thoracic vertebrae: composed of 12 vertebrae, connected to the front ribs including the sternum, forming a stable thorax, which is of positive significance for the protection of the lungs and heart in the thoracic cavity. The thoracic 10-12 area is the thoracolumbar segment, which is usually in a relatively straight state, and if there is a bend here, it will produce the corresponding hunchback performance; 3, lumbar vertebrae: there are five lumbar vertebrae, and the physiological protrusion of this area is forward. If the physiological protrusion disappears or is reversed, the patient will feel back pain. The lumbar spine is also the site where lumbar disc herniation and spinal stenosis are likely to occur. Usually, the lumbar spine is under greater stress and is prone to the above problems in the 4/5 and 5/1 sections of the lumbar spine; 4. Sacrococcygeus: 5 sacral vertebrae are fused into 1 sacrum, and 3-4 caudal vertebrae are fused into 1 caudal bone. The tailbone is located at the end of the spine and will form a bone in adulthood. Together with the iliac bones on both sides and the ulna in front, the sacrococcygeus forms the pelvic ring, which helps to protect the organs in the pelvis and at the same time will transfer the strength of the lumbar vertebrae to the lower limbs to play a transitional role. The spine supports the skull at the upper end, connects to the hip bones at the lower end, has ribs in the middle, and serves as the back wall of the thorax, abdomen and pelvis, supporting the trunk, protecting the internal organs, protecting the spinal cord, and carrying out movement. It is recommended to pay attention to sitting posture in daily life and avoid working or studying in the same position for a long time to avoid vertebral injury, which can affect the function of the spine.
