The area of the brain where memory is processed and stored is the __________.
Cerebrum
Cerebrospinal fluid is produced by the choroid plexuses. In which of the following regions can cerebrospinal fluid be made?
lateral ventricles, third ventricle, and fourth ventricle
Cerebrospinal fluid can exit the fourth ventricle via all of the following EXCEPT the __________.
Intraventicular Foramen
Cerebrospinal fluid can exit the fourth ventricle via all of the following
1 Median Aperture 2 Central Canal 3 Lateral Aperture
Which of the following is a correct statement? Which of the following is a correct statement? _Cerebrospinal fluid circulates in the space between the arachnoid and dura mater. _The superior sagittal sinus lies in the falx cerebelli. _Cerebrospinal fluid enters the venous circulation through the arachnoid granulations. _A blocked interventricular foramen will result in an increase in pressure in the third ventricle.
Cerebrospinal fluid enters the venous circulation through the arachnoid granulations.
In what way is the dura mater of the brain different from the dura mater of the spinal cord?
The dura mater of the brain is made of two separate layers.
Which of the following is NOT a function of the specialized ependymal cells that form the choroid plexus?
removal of pathogenic bacteria from the cerebrospinal fluid
Which of the following is a function of the specialized ependymal cells that form the choroid plexus?
_addition of oxygen to the cerebrospinal fluid _addition of organic nutrients from nearby blood vessels to the cerebrospinal fluid _removal of waste products from the cerebrospinal fluid
