Description: The primary pathway of cerebrospinal fluid (CSF) absorption involves the movement of CSF through the cribriform plate foramina and into the lymphatics of the olfactory turbinates. The time of development and the physiological properties of the lymphatic-CSF connections became the objectives of investigation. The issue of development was studied in two species; one in which CSF synthesis begins before birth (pigs) and one in which CSF secretion is up-regulated within the first week after birth (rats). The results suggest that the CSF-lymphatic connections develop around the time of CSF secretion. Presuming that lymphatics are connected to the CSF space, intracranial pressure and intralymphatic pressure should be related. The impact of elevated intracranial pressure on cervical node pressures was investigated in the rat. These data are consistent with the view that CSF-derived water that convects into the lymphatics is absorbed into the blood vessels to establish equilibrium of Starling's forces.
