Lateral view of the right hemisphere with the distribution of the A. cerebri media. 

 Art. FS, art. cer. med. ; I, II, III, IV, V, the five chief branches of the preceding ; Ilia, lateral 

 twigs of the third branch of the A. cer. med. ; Fc, sulcus centralis ; FS, fissura cerebri lateralis [Sylvii] ; 

 JP, sulcus interparietalis ; t, sulcus temporalis superior ; F^-Fy, superior, middle and inferior frontal
