WebFeb 15, 2014 · Cerebrospinal fluid absorption (CSF) at the cribriform plate is mediated by direct extracranial connections to the lymphatic system. Given the accessibility of these pharmacologically responsive vessels we hypothesized that the rate of CSF outflow can be modulated via the intranasal delivery of drugs known to affect lymphatic contractile activity. WebCerebrospinal fluid flows in bulk from sites of production to sites of absorption. Fluid formed in the lateral ventricles flows through the paired interventricular foramina (foramen of Monro) into the third ventricle, then through the mesencephalic aqueduct (aqueduct of Sylvius) into the fourth ventricle.

WebCerebrospinal fluid clearance has been traditionally believed to occur through dural venous sinuses, however, evidence for a route to lymphatic vessels in the nasal cavity has existed for over a century and half. Yet, the anatomical connections at the cribriform plate between the cerebrospinal fluid and the lymphatic system have remained unclear. WebCerebrospinal fluid (CSF) drains through the cribriform plate (CP) in association with the olfactory nerves. From this location, CSF is absorbed into nasal mucosal lymphatics.
