The document summarizes the anatomy of the brain ventricles. It discusses that the brain contains a series of ventricles that hold cerebrospinal fluid (CSF) which is produced by the choroid plexus. There are four ventricles - two lateral ventricles located within the cerebral hemispheres, the third ventricle within the diencephalon, and the fourth ventricle between the pons and medulla. The ventricles are connected through openings and circulate CSF throughout the brain and spinal cord. The document provides detailed descriptions of each ventricle including their locations and surrounding structures.

• CSF is created by
the choroid plexus
and circulates
through the
ventricles until it is
absorbed by the
arachnoid layers.

4. • CSF seems to
1. act US a fluid cushion for the brain
2. transport some substances into/out of the brain
3. maintains pressure around the brains.

BRAIN VENTRICLES
 The brain is bathed by the
cerebrospinal fluid (CSF)
 Inside the brains, there are
spaces (ventricles) filled
with CSF
 There are 4 ventricles
 2 lateral ventricles are
in the brain hemispheres
 3rd _ ventricle is in the
diencephalon
 4 years ventricle is
between the pons,
medulla and the

6.  They are connected by
 The foramen of monro
• (lateral - > thirds),
 Cerebral aqueduct
• ( third - > fourth), and
 The foramen of magendie and luschka
• (fourth - > subarachnoid
• space/cisterna magna).

Fourth ventricle communicates with the subarachnoid
space through a single median and two lateral apertures.
 in the midline ,the roof is
pierced by a large aperture, the
median aperture or foramen of
Magendie .

around the sides of the medulla
and open anteriorly US the
lateral openings of the fourth
ventricle, or the foramina of
Luschka .

The posterior inferior cerebellar arteries.
 The choroid plexus has a T
shape
 The vertical part of the T
