The vertebral column, also known as the backbone or spine, is part of the axial skeleton. The vertebral column is the defining characteristic of a vertebrate in which the notochord (a flexible rod of uniform composition) found in all chordates has been replaced by a segmented series of bone: vertebrae separated by intervertebral discs.
The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.
The vertebral body is the largest and most supportive part of the vertebra. As discussed above, the vertebral body is a large roundish structure that provides weight support through the column. The vertebrae stack on top of of one another at the vertebral bodies.
Parts of the Spine – Anatomy, Picture, Spinal Column, Backbone. Posted by Dr. Chris. The vertebral column is the most important collection of bones to maintain stability of the skeletal structure and support of the entire body, especially when upright. It is made up of 33 bones, known as vertebra (plural ~ vertebrae), which may be fused at ...
Interactive Parts of the Spine & Vertebrae Sections. 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 basic configuration of a vertebra varies; the large part is the body, and the central part is the centrum. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes.
Parts of the Vertebrae - Thoracic. The thoracic vertebrae are the rib bearing vertebrae. In order to simplify the mechanics of expanding the chest to breath, the thoracic spine is designed to remain stiff and straight no matter what the body is doing.
Anatomy of the Spine. Introduction. Your spine is one of the most important parts of your body. It gives your body structure and support. Without it you could not stand up or keep yourself upright. Your spine allows you to move about freely and to bend with flexibility. Your spine also protects your spinal cord.
Anatomy of the Spine Overview. The spine is made of 33 individual bones stacked one on top of the other. This spinal column provides the main support for your body, allowing you to stand upright, bend, and twist, while protecting the spinal cord from injury.
