Where is the cervical spine located?

The location of the cervical vertebra is relatively obvious. There is a concave area at the back of the head that goes all the way to the highest cervical vertebra in the neck. This is the location of the cervical vertebra. The cervical vertebra is very important for human health and is also an important part that is prone to disease, especially in recent years. With the emergence of some electronic products, playing games and watching mobile phones can easily lead to degenerative lesions of the cervical spine, causing a series of symptoms.

Causes of cervical spondylosis

1. Degeneration of the cervical spine

Degenerative changes of the cervical spine are the main cause of cervical spondylosis, among which the degeneration of the intervertebral disc is particularly important and is the primary factor in the degeneration of the cervical spine structures. From this, a series of pathological anatomical and pathophysiological changes of cervical spondylosis have evolved. ① Degeneration of the intervertebral disc; ② The appearance of the ligament-disc space and hematoma formation; ③ The formation of bone spurs on the edge of the vertebral body; ④ Degeneration of other parts of the cervical spine; ⑤ Reduction in the sagittal diameter and volume of the spinal canal.

2. Developmental cervical spinal stenosis

In recent years, it has been confirmed that the inner diameter of the cervical spinal canal, especially the sagittal diameter, is closely related not only to the occurrence and development of cervical spondylosis, but also to the diagnosis, treatment, selection of surgical methods and prognosis of cervical spondylosis. Some people have severe cervical degeneration and obvious osteophyte hyperplasia, but they do not develop the disease. The main reason is that the sagittal diameter of the cervical spinal canal is wide and there is a large compensatory space in the spinal canal. For some patients, cervical degeneration is not very serious, but the symptoms appear early and are more severe.

3. Chronic strain

Chronic strain refers to various excessive activities that exceed the maximum range of normal physiological activities or the local tolerance value. Because it is different from obvious trauma or accidents in life and work, it is easy to be ignored. However, it has a direct relationship with the occurrence, development, treatment and prognosis of cervical spondylosis. The generation and cause of this kind of strain mainly come from the following three situations: (1) Improper sleeping position. Improper sleeping position will inevitably cause imbalance of paravertebral muscles, ligaments and joints because it lasts for a long time and cannot be adjusted in time when the brain is in a resting state. (2) Improper working posture. A large amount of statistical data shows that the incidence of cervical spondylosis is particularly high among people who have a small workload and low intensity of work but are sitting, especially those who work with their heads down. These people include houseworkers, embroiderers, office staff, typists, assemblers on instrument assembly lines, etc. (3) Inappropriate physical exercise. Normal physical exercise is good for health, but activities or exercises that exceed the neck's tolerance, such as handstands or somersaults with the head and neck as the weight-bearing support points, can increase the load on the cervical spine, especially without proper guidance.

4. Congenital malformation of the cervical spine

When performing health examinations or comparative research radiographs on the cervical spine of normal people, various abnormalities are often found in the cervical spine segments, of which obvious bone deformities account for about 5%.
