Project Description

The PICA is one of the main arteries that supply the cerebellum. Its tortuous path is often misrepresented and difficult to picture. For that reason, this illustration shows the pathway of the PICA and highlights the location of each of its five segments relative to the surrounding anatomy. This piece features a sagittal cross-section of the brain and an inset showing an uncut brain. In the main image, the right branch of the PICA is shown, highlighting its path over the tonsil of the cerebellum, only visible in cross-section. In the inset, the left branch of the PICA is used to show the pathway of PICA over the medulla. The didactic colors showing the segments of PICA are in a palette with enough contrast to be distinguishable for different kinds of color-blindness.
