The ciliated ependymal cells that line the floor of the fourth ventricle in adult Wistar rats are overlaid by an immense network of supraependymal nerve fibres. This study presents morphological evidence of a characteristic association of supraependymal nerve fibres with the cilia of the ependymocytes of the ventricular surface. It is found that the supraependymal nerve fibres accumulate and/or terminate at the base of the clusters of ependymal cilia. These fibres are varicose in nature and consist of large-diameter fibres with numerous prominent varicosities and small-diameter fibres with less frequent and less prominent varicosities. The characteristic association of the supraependymal nerve fibres with the ciliated ependymocytes suggests that these nerve fibres may be involved in producing co-ordinated ciliary movements in the mammalian brain.
成年Wistar大鼠第四脑室底部衬有的纤毛室管膜细胞被巨大的室管膜上神经纤维网络覆盖。本研究提供了形态学证据，表明室管膜上神经纤维与脑室表面室管膜细胞的纤毛存在特征性关联。研究发现，室管膜上神经纤维在室管膜纤毛簇的基部聚集和/或终止。这些纤维本质上是曲张的，由具有大量明显曲张的大直径纤维和曲张较少且不明显的小直径纤维组成。室管膜上神经纤维与纤毛室管膜细胞的特征性关联表明，这些神经纤维可能参与了哺乳动物大脑中协调的纤毛运动。
