Spinal 2 Flashcards
Gives rise to astrocytes and oligodendrocytes
glioblasts (glue)
most numerous cell of the CNS?
astocytes
second most common cell of the CNS, form myelin around CNS?
oligodendrocyte
line CNS, ciliated, make leaky barrier between CSF and CNS?
ependymal cells
Phagocyte of the CNS?
microglia, aka gitterzellen, not many-phagocytes and macrophages
makes neurons
neuroblast
between two hemispheres?
commissural
different parts in the same hemisphere?
association
lower centers to cerebral cortex?
“WHOOOOOP ^^^” projection
most common cell type in the CNS?
multipolar
gray matter contains?
cell bodies and dendrites
white matter contains?
myelinated axons
function as active transport for glucose filters in the CNS
astrocytes
ventricles of the brain are direct extensions of?
spinal cord
what are the primary vesicles of the brain?
PMR prosencephalon, mesencephalon, rhombencephalon
what are the secondary vesicles of the brain?
telencephalon, diencephalon, mesencephalon, metencephalon, myencephalon (tel, di, mes, met, my)
arterial anastomosis supplying blood between forebrain and hindbrain?
circle of willis
anatomically, the circle of willis is around what structure(s)?
pituitary gland and optic chiasm
what supplies the circle of willis?
internal carotid and vertebral arteries
what arteries make the actual circle of willis?
anterior and posterior cerebral and anterior and posterior communicating
where is the most common location for a cerebral vascular accident?
middle cerebral artery
which artery carried the most blood in the circle of willis?
middle cerebral artery
which trunk in the circle of willis sends 200 branches into the ventral aspect of the cord?
AMLAT-anteromedial longitudinal artery trunk
in the circle of willis, these branches supply blood to posterior roots of the spinal cord
PLLAT-posterolateral longitudinal artery
AKA Pallium, developed from the neural plate
cerebral cortex
this vesicle of the brain is mostly formed by the thalamus
diencephalon
this vesicle of the brain is responsible for processing sensory info, sleep, consciousness, motor relay, and relay for the cortex
diencephalon
this part of the brain is responsible for postural adjustments, steadying VOLUNTARY movements, enkephalins and includes the corpus striatum, amygdaloid nucleus and claustrum
basal ganglia
striatal lesions in this area of the brain would cause Parkinson’s, Huntington’s chorea and ballism
basal ganglia
