According to Chinese experts, diseases of the vertebrae in the cervical region (osteochondrosis) most often appear after 30 years of age and are manifested by a whole group of signs and symptoms, according to Pannochka, an online publication for girls and women from 14 to 35 years old.. net Describing the anatomical features of the 3rd-7th vertebrae of the cervical region, it should be noted that their bodies are relatively small, oval in shape, the upper and lower surfaces of the vertebral body have a longitudinal cavity that ends with tubercles.

They are called uncinate processes in Chinese medicine..

The protruding lateral edges of the uncinate processes of the upper surface of the underlying vertebra and the lateral depressions of the lower surface of the body of the overlying vertebra form articular joints of the uncinate processes, called synovial joints.. Synovial joints separate the intervertebral discs and foramina, preventing pathological penetration of fibrils of the fibrous ring of the intervertebral disc into the intervertebral foramen..

The structure of these joints increases the stability of the position of the vertebrae, disorders in this joint lead to a narrowing of the intervertebral distance and compression of the spinal nerves. The articular processes of the cervical vertebrae, when viewed from above, have the appearance of an almost flat oval surface, which is slightly beveled. Each underlying vertebra is larger than the one above.

Chinese anatomists believe that due to such an organization of the articular processes, according to the type of slope, the intervertebral joint provides the direction of the sliding movement of the vertebrae back..

The articular bag formed by the articular processes of the intervertebral joint does not have great elasticity. Inside the joint capsule is a loose synovial membrane that produces synovial fluid.. With atrophy of the intervertebral disc, the distance between the vertebrae decreases, as a result of which the walls of the articular bag lose tension and flake.

In this condition, displacement of the vertebrae easily occurs, called subluxation - subluxation (dislocation, in which the articular processes remain partly in contact with each other). In turn, with subluxation, the intervertebral foramens narrow and thus the roots of the spinal nerves are infringed..

Behind the vertebral body there is an arc, which, together with the posterior surface of the body, forms an intervertebral foramen - a small, obliquely located oval-shaped bone tube, the transverse radius of which is greater than the longitudinal.

Spinal nerves pass through the intervertebral foramen, their roots occupy half of the hole, and inside there is a spinal ganglion, behind which is a joint called a small or posterior. Vertebral blood vessels pass in front of it.

From the lateral parts of the vertebral arch, transverse processes extend to the sides, in the middle of which there is a transverse foramen through which the vertebral artery passes..

The vertebral artery departs from the initial part of the subclavian artery, passing through the transverse foramina of the cervical vertebrae (up to the atlas), then through the foramen magnum enters the cranial cavity.

Here, above the pons on the Blumenbach clivus, the left and right vertebral arteries merge to form the basilar artery, which supplies blood to the spinal cord, temporal and occipital lobes of the cerebral cortex, and cerebellum..
