Hydrocephalus

The obstruction of CSF flow within the ventricular system.

The active distension of the ventricular system of the brain due to an imbalance between CSF production and absorption. (correct)

The expansion of ventricles secondary to brain shrinkage from a diffuse atrophic process.

The obstruction to CSF flow outside the ventricular system.

CSF is secreted predominantly by the choroid plexus of the lateral, third, and fourth ventricles. (correct)

CSF flows in a caudal direction through the ventricular system and exits through the foramina of Luschka and Magendie into the subarachnoid space.

CSF absorption occurs through the arachnoid granulations into the venous system.

CSF is produced at a rate of 500 ml/day (0.35 ml/min).
