[Ultrastructure of the vascular plexus villi in the lateral cerebral ventricle of the cat].
As demonstrates a light and electron microscopic investigation of the villi in the vascular plexuses of the cat cerebral lateral ventricles, the cells of the unilayer epithelium covering their surface differ from the cells covering the cerebral meningitis and from the ependymocytes. The electron microscopic investigation has demonstrated that epithelium covering the villi of the vascular plexuses is not homogenous: 3 main types of the cells are revealed in it. Ultrastructure of the connective tissue stroma of the vascular plexuses, their microcirculatory bed are also not identical to the corresponding parts of the ependyma and the cerebral menings. A conclusion is made that not only the function, but also the structure of the vascular plexuses in the brain have a number of peculiarities that differ them from other intracranial organs.
