- The mammalian nervous system is arranged with the neural tube running along an anterior to posterior axis, from nose to tail for a four-legged animal like a dog. Humans, as two-legged animals, have a bend in the neuraxis between the brain stem and the diencephalon, along with a bend in the neck, so that the eyes and the face are oriented forward. (en)
- The embryonic brain develops complexity through enlargements of the neural tube called vesicles; The primary vesicle stage has three regions, and the secondary vesicle stage has five regions. (en)
