CSF Flow Pattern Flashcards
Cavity in the brain that fills with CSF
Ventricle
of lateral ventricle(s)
2
A cavity located int he interior of each cerebral hemisphere
Lateral Ventricles
Largest ventricles
Lateral
Separates the lateral ventricles
Septum pellucidum
Each lateral ventricle communicates with the third ventricle via the __________
Interventricular foramen of Monro
of third ventricle(s)
1
The narrow ventricle that Is located between the thalamus on each side
third
The third ventricle is located between the ___ on each side
thalamus
Third ventricle communicates with the fourth ventricle via the ______
cerebral aqueduct of Sylvius
of fourth ventricles
1
Ventricle located in the pons and medulla
fourth ventricle
Ventricle continuous with the central anal of the medulla, which, in turn, is is continuous with the central canal of the spinal cord
fourth ventricle
Fourth ventricle opens by the means by _______ into the ________
one medial and two lateral apertures; subarachnoid space
Only means by which the CSF formed int he ventricles enter the subarachnoid space
one Medial Foramen Magendie & 2 Lateral Foramen of Luschka
Lines certain sites in the ventricle
choroid plexus
Function of the choroid plexus
produce CSF
CSF is ___
clear
colorless
acellular fluid
similar to blood plasma
Functions of CSF
To cushion and support the brain and spinal cord
a lymphatic system
an environment of neurons
Pathway of CSF
Right/Left Lateral ventricle –> Interventricular foramen of monro –> Third ventricle –> cerebral aqueduct of Sylvius –> Fourth ventricle –> 2 Foramen of Lushcka, One Foramen of Magendie –> Subarachnoid space –> Arachnoid granulations –> CSF is reabsorbed and passes through the lateral lacunae –> drains into superior sagittal sinus –> into the venous system
