The<unk>  cornu (frontal horn,<unk>  horn; precornu) passes forward and lateralward, with a slight inclination downward, from the interventricular foramen into the frontal lobe, curving around the<unk>  end of the caudate nucleus.
Its floor is formed by the upper surface of the reflected portion of the corpus callosum, the rostrum.
It is bounded medially by the<unk>  portion of the septum pellucidum, and laterally by the head of the caudate nucleus.
Its apex reaches the posterior surface of the genu of the corpus callosum.
