title: [Postnatal histogenesis of the ependymal layer of the human spinal cord and its organogenetic transformation].
abstract: The structure and histochemistry of the ependymal layer in the spinal cord were studied light optically and electron microscopically at the age of birth up to 96 years in 200 persons of both sex died from various trauma. At 18-20 years of age in the lumbar part (L1-L5), as a result of the subependymal cells proliferation, an abundantly innervated  and vascularized intraspinal organ is formed, which has the connective tissue stroma and ectoglial parenchyma. The parenchymal cells are rich in active oxidoreductases and phosphatases, with a well represented granular endoplasmic reticulum, mitochondria, laminar complex and electron opaque inclusions in them, their dynamic changes being connected with the production of Gomori-positive secretion. Certain changes are mentioned in the development of the organ: the initial, early, completed formation and the period of involution.
