Although the brain is exceedingly complicated, an understanding of the basic features of brain development makes it easier to learn and remember the location of the most important structures. With that end in mind.
Development of the Central Nervous System
The CNS begins its existence early in embryonic life as a hollow tube, and it maintains this basic shape even after it is fully developed.
The CNS contains three interconnected chambers. These chambers become ventricles and the tissue that surrounds them becomes the three major parts of the brain, The Forebrain, The Midbrain and The Hindbrain. As development progress the rostral chamber divides into three separate chambers which become the two lateral ventricles and the third ventricle. The region around the lateral ventricles becomes the telencephlon (end brain) and the region around the third ventricle becomes the diencephlon (interbrain). In its final form the chamber inside the midbrain (mesencephalon) becomes narrow, formatting the cerebral aqueduct and two structures develop in the hindbrain: the metencephlon (after brain) and the myelencephlon (marrow brain).
