Ventricles of the Brain - Lecture 3 Flashcards
where do the ventricles of the mature brain originate from
from the fluid filled cavities in the developing neural tube of the embryo
what are ventricles filled with
CSF produced by the choroid plexus
what are the ventricular surfaces are lined by
ependymal cells
ventricles of the brain
lateral ventricles
third ventricles
fourth ventricle
lateral ventricles
2 lateral ventricles are the 2 largest of the ventricles
what shape are the lateral ventricles
irregular
what do the lateral ventricles consist of
a central part
central part has a anterior, posterior and inferior horns
third ventricle
median (midline) cavity
bounded by the thalamus and hypothalamus on either side
anteriorly third ventricle
communicates with the lateral ventricle
posteriorly third ventricle
communicates with what is called the aqueduct of the midbrain
fourth ventricle is the most _____
inferior
where does the fourth ventricle extend from
the aqueduct of the midbrain tot he central canal of the upper end of the spinal cord
where does the fourth ventricle extend from
the aqueduct of the midbrain tot he central canal of the upper end of the spinal courd
what does the fourth ventricle communicate by
the 2 foramina of Luschka and the foramen of Magendie
where does CSF fluid escape through
foramen magendie and lateral apertures
