Flashcards in Primary and Secondary Vesicles of the Brain and Differentiation Deck (20):
1

primary vesicles of the brain

prosencephalon, mesencephalon, rhombencephalon

2

prosencephalon gives rise to

telencephalon and diencephalon

3

telencephalon gives rise to what structures CN

forebrain, CN I

4

telencephalon neural canal regions

lateral ventricles separated by septum pellucidum

5

diencephalon gives rise to structures and CN

thalamus, hypothalamus, pineal, retina, mam body, post pit CN II

6

diencephalon neural canal regions

foramen of monroe (aka interventric foramen) = 1&2 to 3rd ventricle

7

mesencephalon structures and CN

midbrain CN III, IV

8

mesencephalon neural canal regions

cerebral aqueduct of sylvius

9

rhombencephalon gives rise to

metencephalon and myelencephalon

10

metencephalon gives rise to structures and CNs

PONS and cerebellum CN V, VI, VII, VIII

11

myelencephalon gives rise to ? structure and CNs

medulla oblongata CN IX, X, XI, XII

12

met and myelencephalon neural canal regions

4th ventricle

13

median aperture (1)

foramen of magendie

14

lateral apertures (2)

foramina of luschka

15

arterial anastomosis around the pituitary gland and optic chiasm supply of blood between forebrain and hindbrain

circle of willis

16

arteries which supply circle of willis

internal carotid and vertebral arteries

17

arteries which make the circle of willis

anterior and posterior cerebral, anterior and posterior communicating

18

MC location for cerebral vascular accident (CVA); carries more blood than other arteries (~800mL/min)

middle cerebral artery

19

aka anterior spinal artery; sends 200 branches into ventral aspect of cord

anteromedial longitudinal artery trunk AMLAT

20

aka posterior spinal artery; branches provide blood to posterior roots of spinal cord

posterolateral longitudinal artery trunks (PLLAT)
