The anterior horn of the lateral ventricle (also anterior cornu of the lateral ventricle, frontal horn of the lateral ventricle, precornu) is a portion of the lateral ventricle that passes forward and laterally, with a slight inclination downward, from the interventricular foramen into the frontal lobe, curving around the anterior end of the caudate nucleus

Caudate nucleus

The caudate nucleus is a nucleus located within the basal ganglia of the brains of many animal species. The caudate nucleus is an important part of the brain's learning and memory system.-Anatomy:...

. Its floor is formed by the upper surface of the reflected portion of the corpus callosum, the rostrum

Rostrum of corpus callosum

The anterior end of the corpus callosum is named the genu, and is bent downward and backward in front of the septum pellucidum; diminishing rapidly in thickness, it is prolonged backward under the name of the rostrum, and is connected below with the lamina terminalis, which stretches from the...

. It is bounded medially by the anterior portion of the septum pellucidum

Septum pellucidum

The septum pellucidum , and not to be confused with the medial septum, is a thin, triangular, vertical membrane separating the anterior horns of the left and right lateral ventricles of the brain...

, and laterally by the head of the caudate nucleus. Its apex reaches the posterior surface of the genu of the corpus callosum

Genu of the corpus callosum

The anterior end of the corpus callosum is named the genu, and is bent downward and backward in front of the septum pellucidum; diminishing rapidly in thickness, it is prolonged backward under the name of the rostrum, which is connected below with the lamina terminalis...
