Focusing on the corpus callosum you can see the rostrum, genu, body, and splenium. The genu is the major bend at the rostral end, with the rostrum extending caudally and ventrally from the genu. As is the case in many structures, the body is the majority of the corpus callossum, The splenium is at the caudal end of the body.
The callossal sulcus runs the length of the corpus callosum. The cingulate gyrus is jut above that and this gyrus is bounded dorsally by the cingulate sulcus.
