Body
was changed:
The Splenialsplenial artery or(or posterior pericallosal artery) arises most commonly from the parieto-occipital branch of the PCAposterior cerebral artery. It represents an important potential collateral supply from the posterior to anterior cerebral arteries as it anastomoses withvia the pericallosal artery. When a sizeable direct anastomosis is present, it is referred to as a persistent limbic arch4.
