Vertebral Column

The Vertebral Column is part of the skeleton of vertebrates, including humans. It is also called the spine.

The spine consists of vertebrae connected to each other by intervertebral discs. In total, there are 33-34 vertebrae in the human spine. The spine performs a supporting function, protects the spinal cord, and also provides flexibility to the body.

The spinal column is divided into sections:

  1. Cervical spine (7 vertebrae)
  2. Thoracic region (12 vertebrae)
  3. Lumbar (5 vertebrae)
  4. Sacral section (5 fused vertebrae)
  5. Coccygeal region (4-5 fused vertebrae)

The spine has natural curves - cervical and lumbar lordosis, as well as thoracic and sacral kyphosis. The curves of the spine absorb the load on the spinal column during movement and vertical position of the body.

Thus, the spinal column performs many important functions in the human body. The health and mobility of a person directly depends on its condition.



VERTEBRAL COLUMN, vertebral column, or spine (soma vertebrata, chorda vertebralis) is the axial skeleton of the head and neck of terrestrial vertebrates.

The spinal column consists of the cranial shaft and the neck skeleton, consisting of the spinal column, ribs and skull. All this together is the load-bearing support of the spine.

Consists of vertebrae arranged in a certain sequence. In total, vertebrates have 7 types of vertebrae: spinous, transverse, arcuate. The body is located at the junction of the bodies of 2 adjacent vertebrae. One end of the rod is attached to the skull, and the other ends with the caudal trunk in fish, turtles and crocodile, tail spears in bats, birds, reptiles, cartilage
