neuro III Flashcards
Basal plate of brain becomes
umn center and LMN nuclei
brain stem: neural canal expands ____ (direction)
dorsally
alar plate structures shift
laterally and ventrally
basal plate structure
pushed or squeezed medially
white matter of marginzal zone ends up
intermitent with gray matter
neural canal opens into
4th ventricle
alar plate structures shift _____
laterally
basal plate (motor) structure pushed
medially
cerebrum and cerebellum initial organization is
completely redone
gray matter moves
externally
gray matter guided by
glial cells called radial glia
white matter ends up
internal
ependymal cells of ventricular zone line
line ventricular spaces
glandular part of pituitary gland
adenohypothphysis
neural part of pituitary gland
neurohypophysis
goal
neuarl, CNS input to endocrine regulation
what are the sources of adenohypophysis
surface ectoderm in region of developing mouth
what is the source of neurohypophysis
neuroectoderm
stomodeum
endoderm and ectoderm adjacent at cranial end
rathkes pouch of adenohypophysis
a dorsal diverticulum of hat will be the roof of the mouth
eventually loses connection to stomodeum and fuses with
neurohypophysis
ventral diverticulum of stomodeum (floor of developing brain)
neurohypophysis
neurohypophysis retains its connection to diencephalon via a stalk called
the infundibulum
cells of the _____ proliferate around the stalk
adenohypophysis
