Supramarginal Angular Gyrus Anatomy

good illustration of locations of SM vs Ang gyrus.
 
The Supramarginal  (mnemonic:  supra is higher)
gyrus  wraps around the tail end of the LATERAL SULUS (Sylvian fissure) which is
above the Superior Temporal Sulcus.
 
The Angular Gyrus wraps around the tail end of the STS.
 
Note that since those sulci turn northward at their ends
the result is tha the
SM gyrus is ANTERIOR to the SM gyrus.
Also the SM gyrus is much bigger than the Ang gyrus.</p>
