Neurology Embryology Flashcards
the notocord induces overlying ________to differentiate into neuroectoderm and form the neural plate
ectoderm
the neural plate gives rise to
neural tube and neural crest cells
alar plate is
sensory (DORSAL) think of DRG
the basal plate is
motor (ventral)
what does the notochord become
nucleus pulposis of the intervertebral disks in adults
telencephalon gives rise to
cerebral hemispheres and lateral ventricles
diencephalon gives rise to
thalamus and third ventricle
mesencephalon gives rise to
mid brain and aqueduct
metencephalong gives rise to
pons, cerebellum, and upper part of the fourth ventricle
myelencephalon gives rise to
medulla and LOWER part of the fourth ventricle
mid brain is also called
mesencephalon
hind brain is also called the ____-and consists of the _______and ___________
metencephalon, myelencephlon
the forebrain is also called
prosencephalon
the prosencephlong gives rise to
telencephalon and diencephalon
the neural crest cells give rise to
PNS neurons and schwann cells
mesoderm gives rise to what parts of CNS/PNS
microglia
the neuroectoderm gives rise to what
CNS neurons, ependymal cells, oligodendroglia and astrocytes
neuroectoderm for ________and neural crest for ________
CNS, PNS
when time period do the neuralpores close
4th week
when alpha fetoprotein (AFP) is elevated what should you be thinking
neural tube defect
when alpha fetoprotein (AFP) is elevated and then you find they also have elevated acetylcholinesterase then what do you highly suspect with great accuracy
neural tube defect
low folic acid intake is assoc with
neural tube defects
associated with a tuft of hair or skin dimple at the level of bony defect
spina bifida occulta
meninges but NOT the spinal cord herniate through the spinal canal defect, normal AFP
meningocele
