L4 SAQ Ventricles and CSF Route

Name the spaces in order of the route of flow of CSF through to the end.

Lateral ventricles, third ventricle, cerebral aqueduct, fourth ventricle, central canal

For each ventricle, what brain area is it associated with (cerebrum, diencephalon, midbrain)?

Lateral ventricles: cerebrum, Third ventricle: diencephalon, Fourth ventricle: midbrain

What is the function of ventricles?

Ventricles contain cerebrospinal fluid (CSF). Signup and view all the answers

What produces cerebrospinal fluid (CSF)?

Cerebrospinal fluid (CSF) is produced by the choroid plexus. Signup and view all the answers

Where is the choroid plexus located?

The choroid plexus lies inside the ventricles. Signup and view all the answers

How many ventricles are there?

There are a series of ventricles, one is bilateral (a pair with one in each hemisphere) and the others are singular structures along the midline. Signup and view all the answers

What is the route of CSF from formation to the end?

CSF flows from the choroid plexus to the ventricles, then to the venous sinuses. Signup and view all the answers

What are the three core locations of the choroid plexus?

The three core locations of the choroid plexus are the floor of the lateral ventricle, the roof of the third ventricle, and the fourth ventricle. Signup and view all the answers

What is the function of the cerebral aqueduct?

The cerebral aqueduct is a narrow canal through the midbrain of the brainstem that allows CSF to flow from the third ventricle into the fourth ventricle. Signup and view all the answers

Where does CSF go after leaving the ventricular system?

CSF can either exit into the central canal of the spinal cord or into the layer between the coverings (meninges) of the brain. Signup and view all the answers

What is hydrocephalus?

Hydrocephalus is a condition characterized by the overproduction of CSF, failure to drain, or obstruction of flow, which leads to the dilation of the ventricles. Signup and view all the answers
