Describe the basic embryological process behind development of the neural tube - Answer-- the* notochord* induces overlying ectoderm to differentiate into neuroectoderm and form the neural plate (day 18) - the neural plate invaginates to form the *neural tube* and at the same time, cells demarginated from the invaginating tube to form the *neural crest cells* What are the basal and alar plates? What do they give rise to? - Answer-The alar and basal plates are basically the dorsal and vent...
