[0002] The cervical vertebra refers to the cervical vertebrae, which are located below the head and above the thoracic vertebrae, in the cervical segment of the spine. There are 7 pieces in total, surrounding the cervical cord and its spinal meninges, and connected by intervertebral discs and ligaments, forming a physiological curvature that is convex forward. The characteristics of the cervical vertebrae are that the vertebral bodies are small and oval, with transverse foramina on the transverse processes, through which the vertebral arteries and vertebral veins pass; the spinous processes are short and branched; the joints of the upper and lower articular processes are approximately horizontal, so that the neck can move flexibly, and the upper and lower notches of adjacent vertebrae form the intervertebral foramen, through which spinal nerves and blood vessels pass. For cervical diseases, cervical traction is usually used for treatment. Cervical traction uses the principle of action and reaction to generate external force through manipulation, instruments or electric devices, which acts on the human cervical spine, causing a certain separation of tissues and proper stretching of the soft tissue around the joints, thereby achieving the treatment goal.
