The following false about the circulation of the cerebrospinal fluid (CSF) (AIPG 2010)
|A||Produced by the modified ependymal cells of the choroid plexus|
|B||Absorbed mainly through the arachnoid granulations in the superior sagittal sinus|
|C||Ventricular system communicates with the subarachnoid space through the roof of the third ventricle|
|D||Blockage of the Monro foramen causes internal hydrocephalus|
Ventricular system communicates with the subarachnoid space through the roof of the third ventricle
CSF entering the fourth ventricle through the cerebral aqueduct can exit to the subarachnoid space through two lateral foramina of Luschka and a single, midline foramen of Magendie, present on the roof of fourth ventricle.
