Vertebral Column Spinal Cord 3D model
The vertebral column is the defining characteristic of a vertebrate, in which the notochord (a flexible rod of uniform composition) has been replaced by a segmented series of bones—vertebrae separated by intervertebral discs. The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord. In the human vertebral column there are normally thirty-three vertebrae; the upper twenty-four are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx or tailbone. The articulating vertebrae are named according to their region of the spine. There are seven cervical vertebrae, twelve thoracic vertebrae and five lumbar vertebrae. The number of vertebrae in a region can vary but overall the number remains the same. The number of those in the cervical region however is only rarely changed. There are ligaments extending the length of the column at the front and the back, and in between the vertebrae joining the spinous processes, the transverse processes and the vertebral laminae.
This is a model of the human vertebral column spinal cord.
- Approx 132,691 polygons.
- Made entirely with 3 and 4 point polygons.
- Although the model includes parts such as the individual spinal discs, this version of the model is not rigged.
- However, these parts can be hidden or shown to suit the needs of your render or animation.
- The model is UV mapped and a texture and bump map (in tif format) are included, at 640x480 pixels.
