摘要

為瞭解哺乳動物的腦室系統於是我們以樹脂注入老鼠腦室鑄造模型，並以掃描式電子顯微鏡觀察各腦室，以建立比較解剖學的實驗研究模式，由造模型，我們發現老鼠的腦室系統遠較人類者為單純。
由掃描式電子顯微圖觀察到各腦室間的差異性，大部份腦室的內襯具纖毛排列整齊的管室細胞，但是亦有部份不具纖毛或具有少許纖毛的特殊區域，管室上細胞具兩種型態，其一為呈巨噬細胞狀位於脈絡叢，另一為神經元狀出現於松果體隱窩。

In order to establish a good experimental model for comparative studies of the brain ventricular system in mammals, a resin-cast model and scanning electron microscopy were employed to examine the rat brain ventricular system. From the resin-cast model, we found that the gross morphology of the brain ventricular systems of rats is simpler than that of humans. From scanning electron microscopy, local variations of ependymal cells lining the rat brain ventricle were noted. Most areas of the ventricles were lined by ciliated ependymal cells arranged in regular rows, whereas in some other areas nonciliated ependmal cells were also observed. Epiplexus cells and supraependymal cells were also encountered on the top surface of the choroids epithelium, and ependymal cells in ceratin area such as the pineal recess.
