摘要: The mature central nervous system (CNS) is well protected against both mechanical injuries and alterations in the environment outside of brain barriers. protection provided by a bony vault, various membranes, cerebrospinal fluid (CSF) which serves to support cushion CNS trauma. buoyancy CSF indicated fact that weighing 1500 g air weighs only 50 when immersed CSF. Just as skull “hydraulic suspension” provide protection, tight junctions between endothelial cells capillaries, epithelial choroid plexuses arachnoidal meninges, underlying diffusion restraint barriers upon all other mechanisms act (see Dziegielewska & Saunders, this volume).
