Description of the Anterior Cerebral Artery and its Cortical Branches: Variation in presence, origin, and size

The anterior cerebral artery (ACA) supplies the medial hemisphere and its cortical branches include the infra-orbital artery (IfO), frontopolar artery (FpA), anterior internal frontal artery (AIFA), middle internal frontal artery (MIFA), posterior internal frontal artery (PIFA), callosomarginal artery (CmA), paracentral lobule artery (PLA), superior internal parietal artery (SIPA) and inferior internal parietal artery (IIPA). Certain aspects of these cortical branches tend to vary. This includes absent or additional arteries, variation in origin, and changes to the diameter and length.
