Abstract
The current work was carried out on fourty five heads of
adult apparently healthy camels of both sexes. The
specimens were collected from Zagazig and Belbis
slaughter houses.
Twelve brains and meninges specimens fixed and
dissected to reveal the topographical and morphological
features of the choroid plexus of the each ventricle as
well as the arachnoid granulation. The different
measurements of the choroid plexus of each ventricle
include the lengths and widths of different parts were
recorded either in fresh and formalized specimens.
In regarding to three brain specimens were
plastinated by silicon 10 techniques at Zagazig
plastination laboratory. Four specimens were used fresh
for Magnetic Resonant Image and one for Computed
tomography. Five brains were injected by gum milk
colored red by carmine (Latex 60%) and three others by a
mixture of Indian ink and calf serum (1: 1) through
common carotid artery. Seven specimens were prepared
and processed for the histological studies. Five camel
heads were perfused immediately after slaughter with
0.9% physiological saline through the common carotid
artery for scanning electron microscope for choroid
plexus of each ventricle as well as the arachnoid
granulation. Other five camel heads for transmission
electron microscope for the arachnoid granulation.
The choroid plexus of each lateral ventricle was
invaginated along a curved line, known as the
choroid fissure. It began ventrally in the temporal
horn of the lateral ventricle. The one of the third
