This illustration of the lumbosacral plexus was designed for first year medical students completing human anatomy dissections for the first time. Previous depictions of the lumbosacral plexus are almost entirely from an anterior view. The choice to depict an anterior oblique view reflected the angle that student dissections typically take place. By replicating this view, my goal was to improve student comprehension when preparing for dissection and reviewing for exams. I included the psoas major and iliacus muscles on one side as they are commonly encountered during dissection but obscure much of the plexus. An anterior oblique view also presented an opportunity to divide the lumbar and sacral plexuses for further clarity, and show their spatial relationship. My choice to depict both a didactic and schematic version was also done with first year medical students in mind. When first introduced to the region, students must memorize the vertebral origins of each nerve. In the didactic view, the overlapping nerves make it difficult to trace each nerve to its vertebral origin. By including a simplified schematic, my goal was to expedite this process. Finally, the number of colors in the schematic provided a challenge for visual accessibility , however, colors were rigorously adjusted to contrast in value and be accessible to all viewers.
