Quiz on the Ventricular System of the Brain

What are the ventricles of the brain?

• Four lateral ventricles

• Two lateral ventricles, a third ventricle, and a fourth ventricle

• One ventricle in each cerebral hemisphere

• One lateral ventricle and two third ventricles

Where is the choroid plexus located?

• In the dural venous sinus

• In the subarachnoid space

• In the spinal cord

• In each ventricle of the brain

What is the function of cerebrospinal fluid (CSF)?

• Regulates body temperature

• Provides structural support to the skull

• Transports oxygen to the brain cells

• Cushions the brain and spinal cord, gives buoyancy, and reduces weight

Where does CSF flow after being produced by the choroid plexus?

• Into the arachnoid granulations

• Through the interventricular foramen, third ventricle, cerebral aqueduct, and fourth ventricle

• Directly into the bloodstream

• Into the spinal cord

What is the largest ventricle in the brain?

• Cerebral aqueduct

• Third ventricle

• Fourth ventricle

• Lateral ventricle

What connects the lateral ventricles to the third ventricle?

• Interventricular foramen of Monroe

• Cerebral aqueduct

• Median aperture of Magendie

• Lateral apertures of Luschka

How often is cerebrospinal fluid (CSF) replaced inside the ventricular system?

• Every eight hours

• Every day

• Every month

• Every week

Where does CSF drain back into the bloodstream?

• Into the ventricles of the brain

• Arachnoid granulations into the superior sagittal sinus

• Into the subarachnoid space

• Into the spinal cord

What is the function of the cerebral aqueduct?

• Produces CSF in the lateral ventricles

• Filters CSF into the subarachnoid space

• Connects the third and fourth ventricles

• Drains CSF back into the bloodstream

What is the role of the arachnoid granulations in the brain?

• Filter CSF into the superior sagittal sinus

• Produce CSF in the lateral ventricles

• Connect the lateral ventricles to the third ventricle

• Cushion the brain and spinal cord
