: 1. The notochord has a key role in activating differentiation of the the nervous system.
T-the notocord induces growth of the neural plate
: 2. The brain develops in relation to the first 5 somites.
T-cranial to the first 5 somites, the brain develops
: 3. The dorsal roots are derived from the neural crest.
T-if you are asking in relation to the spinal cord, it carries afferent signals
: 4. Postpartum brain growth is mostly due to neuronal proliferation.
F-almost all neuronal proliferation finishes by birth
: 5. The optic nerve is, arguably, an extension of the central nervous system.
T
: 6. The eye develops as a structure of the diencephalon.
T-one of the tissues that contributes to its development, as well as the outpouching
: 7. The optic stalk is a precurser of the optic nerve.
T
: 8. Surface ectoderm and neural crest cells combine to form the cornea.
T
: 9. The peripheral nervous system is mostly from neural crest cells.
T
: 10. The parasympathetic ganglia of the head are derived from neural crest cells.
T?
: 11. The cranial nerve sensory ganglia are derived from neural crest cells.
T
: 12. The sympathetic postganglionic cell bodies are in ganglia derived from the neural crest cells.
T-neurons derived from neural crest cells with bodies that lie in paravertebral or prevertebral ganglia
