Project Description

The foramina of the skull and the structures that pass through them is a complex topic. Being positioned across a varied topology of the skull, leads to these foramina being difficult to visualize. Most anatomical textbooks showing the foramina tend to show the interior cranial base in a standard superior view. This leads to some foramina being hidden, most especially the superior orbital fissure, and on occasion, foramen rotundum. In addition, many structures pass through each of these foramina, including veins, arteries, and nerves. The primary objective of this piece was to improve the visibility of the foramina and provide an overview of which combinations of anatomical structures pass through each of them. To improve visibility, the interior cranial base was illustrated from a superior view with an anterior tilt. For quick identification of structures passing through each foramen, and to distinguish by structure type, color was used as a pre-attentive feature.
