Routine Brain: Ventricular System - Video Lesson

Hey, everybody. Welcome to this lesson on the ventricular system of the brain as seen in MRI. The ventricles play a key role in the production and circulation of cerebrospinal fluid. These are key structures of the brain that a technologist should be able to identify. In this lesson, we will discuss the ventricles, the channels that connect each ventricle, and the flow of cerebrospinal fluid through the system. Let's get started. The ventricular system produces and circulates cerebrospinal fluid or CSF in the brain and eventually down the spinal cord. CSF serves as a cushion to protect the brain and spinal cord from injury. A specialized type of tissue termed the choroid plexus produces CSF by a complex system of secretion and filtration. The choroid plexus tissue is located in all the ventricles of the brain. There are three main ventricles in the brain, the lateral ventricles, third ventricle, and fourth ventricle.
