Abstract

The internal portion of the capsule of the spinal ganglia of rabbit is composed of continuous superimposed layers of flattended cells (perineurium). In replicas, extensive meshworks of strands, presumably forming zonulae occludentes, are found between the perineurial cells of the same layer. Adjacent layers are joint by maculae occludentes located on the lateral processes of the perineurial cells. Occasionally small gap junctions lie within the meshes of the zonulae occludentes.

摘要

兔脊髓神经节被膜的内部由连续叠加的扁平细胞层（神经束膜）组成。在复制品中，在同一层的神经束膜细胞之间发现了广泛的丝状网络，推测其形成了紧密连接。相邻层通过位于神经束膜细胞侧突上的闭锁斑相连。偶尔，在紧密连接的网孔内会有小的缝隙连接。
