====== Bulk flow model ======
The classic bulk flow model of CSF ascribes discrete sites of [[cerebrospinal fluid production]], [[cerebrospinal fluid absorption]], as well as [[cerebrospinal fluid circulation]] routes. While this model may be useful for understanding and treating some aspects of [[CSF]], it is becoming clear that it is inadequate to explain many of the details. [[Pulsatile flow]], [[lymphatic]] channels ([[glymphatics]]) and distributed sites of production and absorption all appear to participate in [[cerebrospinal fluid dynamics]].
