Project Description

The purpose of this piece is to educate first-year medical students on the process of testicular descent and the contents of a developed spermatic cord. The Testes Descent diagram in the upper left corner summarizes the path of the testes, with both it and the spermatic cord illustration at a ¾ orientation to provide an unobscured view of the testes upon its descent. The central illustration summarizes the layers of the abdominal wall and spermatic cord in the inguinal area. Cord layers are thicker than their actual anatomical proportions for improved visibility. Trans-inguinal Phase diagrams on the right further explain testes descent as it leads to spermatic cord layer formation; the phase diagrams lead the reader’s eye to the resulting spermatic cord image to reinforce this relationship. Both the Spermatic Cord Contents and Trans-inguinal Phase diagrams color-code corresponding transitional layers to establish their association. For accessibility consideration, the color-code palette is limited to four colors, which are arranged so that similar values and hues are non-adjacent when viewed with red-green colorblindness filters. Moreover, spermatic cord layer labels include a description of part of the abdominal wall it originated from, providing an alternative way to identify what component is contributing to the cord without solely relying on color.
