The first cervical vertebra.

Collections of illustrative plates, charts, etc., usually with explanatory captions.

In the context of anatomy, "Atlases" refer to comprehensive illustrated reference books that provide detailed descriptions and visual representations of the structures and regions of the human body, often including cross-sectional views from imaging techniques like MRI or CT scans.

Three-dimensional representation to show anatomic structures. Models may be used in place of intact animals or organisms for teaching, practice, and study.

The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.

Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. one without, radionuclide images using different radionuclides, radiograph vs. radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, coloring of vessels in angiograms).
