Throughout the spine, intervertebral discs made of cushioning material both pad and connect the vertebrae. The lumbo-sacral spine includes: Lumbar vertebrae: Numbered L1 through L5, these...
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.
A normal, healthy disc is one of the best parts of the spine. An opening between the pedicles of the vertebrae through which nerve roots exit off the spinal cord. Spinal canal. Contains the spinal cord from the brain stem to the upper lumbar spine. There is no spinal cord in the lower lumbar spine.
Explore the anatomy and structure of the 26 bones that make up the spine with Innerbody's 3D model.
The vertebral column, commonly known as the spine, spinal column, or backbone, is a flexible hollow structure through which the spinal cord runs. It comprises 33 small bones called vertebrae, which remain separated by cartilaginous intervertebral discs.
It is composed of 33 small bones called vertebrae, which are separated by cartilaginous intervertebral discs. The vertebral column forms the axial skeleton, skull bones, ribs, and sternum. Where is the Vertebral Column Situated? The spine begins just below the occipital bone and extends to the tip of the coccyx (tailbone).
Discs: Soft, cushion-like structures located between adjacent vertebrae. They provide shock absorption, flexibility, and support for the spinal column. Spinal cord: A long, tubular bundle of nerves that extends from the brainstem down the vertebral column, protected by fluid in the spinal canal and surrounded by ligaments and bone for protection.
It consists of multiple bones, the vertebrae, stacked on top of each other and separated by shock-absorbing intervertebral discs which provide flexibility to the vertebral column. The spine can be divided into five parts, each with characteristic anatomy: Cervical (neck) - 7 segments or vertebral bodies
Each section has a different number of vertebrae and supports different parts of your body. Strong muscles, bones, flexible tendons and ligaments help your spine stay healthy. However, if they are affected by strain, injury or disease, that can cause pain.
These diagrams and original illustrations were produced from 3D medical imaging reconstructions of the spine and back by Micheau, Antoine - MD. All the images are in vector format, allowing an optimal web display with zoom and shifting of the anatomical images.
