Michael, Ann, and others,
The major anatomical divisions of the central nervous system have their roots
in embryology. To quote from Correlative Neuroanatomy & Functional Neurology,
Joseph G. Chusid, 1970 (an oldie, but a goodie in my opinion (a great picture
book) and not outdated for gross embryology and anatomy):
Early Differentiation
"A thickened plate of ectoderm, the neural plate, develops along the
middorsal line of the embryo and is transformed by invagination into a neural
tube. The neural tube detaches from the overlying ectoderm and thickens to
develop into the spinal cord and brain. The rostral end of the neural tube,
which ultimately forms the brain, differentiates into 3 primary brain
vesicles: (1) the prosencephalon, or forebrain, which lies closest to the
rostrum. (2) the mesencephalon, or midbrain, which lies behind the
prosencephalon; and (3) the rhombencephalon, or hindbrain, which lies most
caudad."
