[Intraspinal organ in man]

In the ependymal zone of the spinal cord at the LI-SIII level an ependymal glandular organ has been described. Its highest secretory activity coincides with the period of the greatest functional activity of the human reproductive system functioning. Certain stages in development of the organ, its cell composition, blood supply, afferent and efferent innervation have been studied. In secretory cells of the organ peptide with cardio- and vasotonic properties has been identified immunochemically. The action of the organ is considered in connection with role, which the ependymal glands of the brain play in regulation of the organism's function.
