RESUMEN
(ABSTRACT)
1- ON THE DEVELOPMENT OF VENTRICLES
The cerebral ventricles stem from the embryonic nervous
neuroepitelio of the system in development. The cerebral
ventricles, the aqueduct and the central conduit of the spinal
marrow are re-dressed by a cap epitelial in cubic cells and
cylindrical called cells ependimarias. The presence of a
prolongation is typical basal in these cells epiteliales.
The lateral ventricles are in the cerebral hemispheres and go
from the frontal lobe up to the occipital lobe. Cavities
constitute anfractuosas for the projections in his(her,your)
interior of more or less pronounced (marked) protuberances of the
cerebral substance The lateral ventricles, as well as other
formations (trainings) cavitarias, there are re-dressed entirely
by cells ependimales that have preserved the own(proper)
characters of the ectodermal coating of the first periods of the
development.
Every lateral ventricle reports with the ventricle
called(named) III by means of Monro's foramen, in such a way that
the liquid cefalorraquídeo contained in them can cross the
whole neural pipe. The ventricle III, with an aspect in funnel
with his(her,your) base up and understood(included)
between(among) the optical talámos, the fórnix and
the top coroides he(she) reports with the ventricle IV described
to level of the bulb by means of Silvio's aqueduct. Of here the
liquid cefalorraquídeo penetrates to the central channel
of the epéndimo, to the center of the spinal marrow, which
reaches up to the level of the vertebra II lumbar.
