LESSON

	

Cerebrospinal fluid (“CSF”) is produced by the choroid plexus at a rate of 20 cc per hour.  The amount of fluid in the ventricles is approximately 50 cc.  Most of the CSF 150 ccs, is outside of the ventricles in the subarachnoid spaces of the fissures, cisterns, sulci, and thecal sac.  The amount of CSF is determined by the rate of production and the rate of absorption.  CSF is re-absorbed through the arachnoid granulations located in the dura along the sagittal sinus.  The CSF circulation pathway begins in the lateral ventricles where the choroid plexi secrete CSF.  

The cerebrospinal fluid moves through the Foramen of Monro into the 3rd ventricle.  From the third ventricle the fluid moves through the Sylvian Aqueduct into the 4th ventricle.  The fluid leaves the 4th ventricle through the foramina of Luschka and Magendie and then moves down into the subarachnoid space surrounding the spinal cord and finally down into the thecal sac in the space surrounding the cauda equina.  The fluid circulates back toward the head and finally is reabsorbed by the arachnoid granulations that line the inner surface of the sagittal sinus.	



脑脊髓液（“脑脊液“）是由在每小时20毫升的速度脉络丛。在脑室液量大约是50毫升。脑脊液150船级社的最多的东西，在外面的裂缝，蓄水池，沟，和硬膜囊脑室蛛网膜下腔空间。而脑脊髓液量取决于生产率和吸收率。 CSF是重新通过在沿矢状窦硬脑膜位于蛛网膜颗粒吸收。脑脊液循环通路开始在那里的侧脑室脉络plexi分泌脑脊液。

脑脊液通过门罗孔进入第三脑室举措。从通过西尔维安渡槽液动进入第三脑室第四脑室。流体离开通过钩椎孔和马让迪第四脑室，然后向下移动到脊髓周围的蛛网膜下腔，最后进入硬膜囊下来马尾周围空间的空间。流体循环回向头部方向，最后是由该行矢状窦的内表面的蛛网膜颗粒吸收。
