Variable Anatomy of the Middle Cerebral Artery from Its Origin to the Edge of the Sylvian Fissure: A Direct Fresh Brain Study

Figure 5

Cortical branches of the MCA. The number of cortical branches varied; 7 (a), 9 (b), 12 (c), and 13 (d) cortical branches are shown as examples. The identified cortical branches were orbitofrontal (OF), prefrontal (PF), precentral (PC), central (C), anterior parietal (AP), posterior parietal (PP), angular (An), temporopolar (TP), anterior temporal (AT), middle temporal (MiT), posterior temporal (PT), and temporo-occipital (TO). The MT and bifurcation (Bi) of the MCA and ICA are indicated. Optic chiasma.
