Flashcards in Embryology of the CNS Deck (27):
1

when does the cranial neuropore form

26

2

when does the caudal neuropore close

28

3

what are the three layers of the developing neural tube

ependymal layer
mantle layer
marginal layer

4

which layer of the developing neural tube develops into the gray matter

mantle layer

5

which layer develops into the white matter

marginal layer

6

the mantle layer divides into

alar and basal plates

7

basal plate is

motor

8

alar plate

sensory

9

failure of cranial neuropore to close results in

anencepahly

10

what are the three basic regions of the adult brain

forebrain
midbrain
hindbrain

11

prosencephalon divides into

telencephalon and diencephalon

12

rhombencephalon

metencephalon
mylecephalon

13

components of myelencephalon

medulla and lower 4th ventricle

14

components of metencephalon

pons, cerebellum, and upper 4th ventricle

15

components of mesencephalon

midbrain and cerebral aqueduct

16

components of telecephalon

cerebral hemispheres and lateral ventricles

17

components of diencephalon

thalamus, hypothalamus, epithalamus, subthalamus, and third ventricle

18

craniopharyngiomas

diabetes, pituitary problems persistent rathke's pouch

19

major visual impairment, developmental delays and chronic headaches results in

craniopharyngiomas

20

oder of innervation along the neural tube

GSE, GVE, SVE, GVA/SVA, SSA, GSA

21

what week becomes sulci and gyri

30 weeks

22

3rd trimester and continues after birth

23

Band Heterodopia

double cortexism, extra band of what matter

24

what is schizencephaly

large clefts in the brain

25

absence of the cerebellum vermis

dandy walker syndrome

26

recurrent seizures/ not as many sulci or gyri

lissencephaly

27

herniation of the cerebellum

arnold chiari syndrome
