Explanation:

The choroid plexus (also known as plica choroidea) is a highly vascularized structure composed of capillaries covered by a layer of specialized epithelial cells, whose main function is to produce cerebrospinal fluid (CSF). The third ventricle is a cavity filled with CSF which is found between the two halves of the brain. The fourth ventricle is a cavity that contributes to the formation of the CSF-filled central canal which runs along the length of the spinal cord. The lateral ventricles are the two largest ventricles filled with CSF. The left ventricle and right ventricle are located in the left and right cerebral hemispheres, respectively. The interventricular foramen is a channel located between the lateral ventricles and third ventricle, thereby connecting these ventricles and thus allowing CSF to pass between them. The septum pellucidum is a double membrane structure located in the midline of the brain (i.e., between both cerebral hemispheres), which separates the frontal horns and bodies of the lateral ventricles in the midline. Finally, the cerebral aqueduct is a structure located within the midbrain (also filled with CSF) that connects 3rd and 4th ventricle.
