The hindbrains and meninges of the pigeon and chick have been examined by light and electron microscopy. Serial section histology of the skull with the brain and meninges intact has shown that the caudal end of the roof of the fourth ventricle consists of an extensive membranous pouch which projects caudally and dorsally into the subarachnoid space. Electron microscopy of selected areas of the membranous pouch in pigeon has shown it to consist of two components: ependymal cells and pial tissue. The membrane ependymal cells are squamous, adjacent cells being linked by intermediate junctions. At the junction with the surface of the medulla the ependymal cells are continuous with the ventricular ependyma, and at the choroid plexus they are continuous with the choroid plexus epithelium. These results are discussed in relation to the fluid spaces in and around the hindbrain.
已通过光学显微镜和电子显微镜对鸽子和小鸡的后脑及脑膜进行了检查。对带有完整大脑和脑膜的颅骨进行连续切片组织学检查显示，第四脑室顶部的尾端由一个广泛的膜性袋组成，该膜性袋向尾侧和背侧突出至蛛网膜下腔。对鸽子膜性袋选定区域的电子显微镜检查表明，它由两部分组成：室管膜细胞和软膜组织。膜性室管膜细胞呈鳞状，相邻细胞通过中间连接相连。在与延髓表面的交界处，室管膜细胞与脑室室管膜连续，在脉络丛处，它们与脉络丛上皮连续。结合后脑内及周围的液体间隙对这些结果进行了讨论。
