Project Description

​This illustration was created to supplement several different clinical vignette explanations involving priapism. The pathophysiology of priapism is described in the context of the physiology of healthy erection and detumescence. To narrow the scope of the image, emphasis was placed on sympathetic and parasympathetic input, relaxation of smooth muscle, and how increased arterial inflow impedes venous outflow. Students typically spend less than two minutes reviewing these explanations. In order to limit extraneous and distracting information, schematic illustrations were used to describe the two different states while flowcharts summarize the sequences of events that lead to them. The image was style-matched and composed in a way that allows it to be quickly adapted for other clinical vignette explanations concerning the physiology of erection and detumescence.
