Exam Questions and Answers | 100%
1
Solved
embryological development: sequence of events - 🧠 ANSWER ✔✔1.
neurulation 2. cell proliferation 3. migration & aggregation 4. cell
differentiation 5. synaptogenesis
neurulation - 🧠 ANSWER ✔✔formation of neural crest and neural tube from
ectoderm, mesoderm, and endoderm; neural tube becomes CNS; fluid-
filled cavities within neural tube become ventricles
cell proliferation - 🧠 ANSWER ✔✔within the neural tube;
ependymal or germinal layer-->lining of ventricles
intermediate or mantle layer-->gray matter
marginal layer-->white matter
migration & aggregation - 🧠 ANSWER ✔✔of cells within definitive locations;
radial migration-->vertical

, tangential migration-->horizontal/transverse (associated with movement of
brainstem)
2
cell differentiation - 🧠 ANSWER ✔✔formation of axonal & dendritic
processes; development of cranial nerves
synaptogenesis - 🧠 ANSWER ✔✔formation of connections between nerve
cell to nerve cells or muscle cells; basis for neural plasticity
deficits in neurulation - 🧠 ANSWER ✔✔failure of neural tube to close:
posteriorly-->spina bifida, anteriorly-->anencephaly
prosencephalon - 🧠 ANSWER ✔✔forebrain-->telencephalon &
diencephalon
diencephalon - 🧠 ANSWER ✔✔thalamus, hypothalamus, optic nerves,
neurohypophysis, pineal gland
mesencephalon - 🧠 ANSWER ✔✔midbrain
rhombencephalon - 🧠 ANSWER ✔✔metencephalon (cerebellum and pons)
and myelencephalon (medulla)
function of brainstem - 🧠 ANSWER ✔✔basic bodily functions necessary for
survival (e.g. HR, BP, RR)
