Quiz #4 - CNS - The Circulation of Cerebrospinal fluid (A&P)

CSF is produced and secreted by __________ in all ventricles of the brain.

choroid plexus

Ependymal cells in the choroid plexus use __________ to produce the CSF.

blood

Ependymal cells produce and circulate about __________ mL of CSF a day.

500

Motile cilia on ependymal cells create currents that circulate CSF through the __________ and other circulatory structures.

ventricles

The lateral ventricles are the 1st and 2nd ventricles separated by a thin membrane called __________.

septum pellucidum

The lateral ventricles drain into the __________ through 2 intervertebral foramina.

third ventricle

The third ventricle drains into the fourth ventricle via the __________ which passes through the midbrain.

cerebral aqueduct

The fourth ventricle is located between the pons, medulla oblongata, and __________.

cerebellum

The fourth ventricle drains into the subarachnoid space around the brain via the __________ and the median aperture.

L and R lateral apertures

The fourth ventricle also drains into the __________ of the spinal cord.

central canal

Hydrocephalus is the accumulation of __________ in the CSF circulation.

CSF

One cause of hydrocephalus is __________ drainage.

slow CSF

Blockage of the CSF circulation pathway can lead to __________.

hydrocephalus

In newborns, hydrocephalus can cause the __________ to swell and expand.

skull

If hydrocephalus develops after skull bones are fused, it can cause brain damage due to increased __________.

pressure

The fluid-filled space inside the diencephalon is the __________.

third ventricle

The two large C-shaped spaces in the cerebrum are the __________ ventricles.

lateral

The CSF circulates through the brain and spinal cord in a system outlined in the __________ flow chart.

CSF circulation

CSF is secreted by tissue called __________ located in the brain's ventricles.

choroid plexus

The cerebral aqueduct connects the third and __________ ventricles.

fourth

The __________ apertures allow CSF to drain from the fourth ventricle into the subarachnoid space.

lateral

In adult patients, hydrocephalus can lead to increased pressure in the __________ cavity.

cranial

The __________ is the collection of spaces where CSF circulates around the brain.

subarachnoid space

Motile cilia on ependymal cells help in __________ CSF.

circulating

Excess CSF secretion can cause __________ in the CSF circulation.

hydrocephalus
