Vertebrae are numbered and named according to where they are located in the spinal cord. The spine is divided into four regions which contain vertebrae: the cervical, the thoracic, the lumbar, and the sacral. Hover over each part to see what they do.
The entire spinal column consists of 33 individual bones called vertebrae, plus two sections of naturally fused vertebrae – the sacrum and the coccyx – located at the very bottom of the spine. All of these bones and sections are important to the spine’s ability to function properly.
The spine contains 5 lumbar vertebrae (L1-L5) that support the body weight. They have large, kidney-shaped vertebral bodies, triangular vertebral foramina, and short spinous processes. Among all the vertebrae, the L5 lumbar vertebra is the largest.
It comprises 33 small bones called vertebrae, which remain separated by cartilaginous intervertebral discs. The vertebral column forms the axial skeleton, skull bones, ribs, and sternum. The spine starts just below the occipital bone and extends up to the tip of the coccyx (tailbone).
Adults typically have 33 bones called vertebrae, that interlock with each other to form the spinal column. The vertebrae are divided into five regions or sections: Cervical; Thoracic; Lumbar; Sacrum; Coccyx; Each section has a different number of vertebrae and supports different parts of your body.
Patient Education Spine Diagrams. The human spine consists of 33 vertebrae: 7 Cervical vertebra (C1-C7) 12 Thoracic vertebra (T1-T12) 5 Lumbar vertebra (L1-L5) The sacrum and coccyx are made up of 9 fused vertebrae Each vertebra is attached to the one above and below it by ligaments and muscles.
Lateral labeled diagram of the human vertebral spinal column showing vertebrae numbering order and the 5 different regions of the spine. Continued... The Atlas is the topmost vertebra, and along with C2, forms the joint connecting the skull and spine.
Vertebrae: Your spine has 33 stacked vertebrae (small bones) that form the spinal canal. The spinal canal is a tunnel that houses your spinal cord and nerves, protecting them from injury. Most vertebrae move to allow for a range of motion. The lowest vertebrae (sacrum and coccyx) are fused together and don’t move.
On "Anatomical parts" the user can choose to display the various structures in colored illustrations of the anatomy of the back and spine: vertebrae, bones, joints, ligaments, muscles, muscular system, fascia, arteries, veins, nerves and various adjacent organs.
Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.
