what are the stages involved in the embryonic development of the brain
the embryo is covered in a layer called the ectoderm , this ectoderm will
become the epidermis of the skin which is the part we see the outer most layer
of the skin.
the ectoderm will form a groove along the dorsal midline ( at the back of the
embryo in the middle ) and during day 20 of conceiving the groove will be
deeper and will now fuse to a neural tube.
the part that did not fuse becomes a neural crest and the neural tube will form
the CNS and the neural crest will be the ganglia of the PNS.
what are the 3 primary vesicles or 3 principle regions that form the developing brain
forebrain > prosencephalon
midbrain > mesencephalon
hindbrain > rhombencephalon
what does the forebrain divide into during the 5th week
telencephalon
diencephalon
what does the midbrain divide into during the 5th week
remains the midbrain or mesencephalon
what does the hindbrain divide into during the 5th week
metencephalon
myelencephalon
the metencephalon develops into the walls of the
pons and cerebellum
the myelencephalon develops into the walls of the
