Résumé : The lining of the third ventricle has been observed by transmission and scanning electron microscopy in the rat and in man. The upper part of the third ventricle is covered by cuboidal cells presenting numerous kinetocilia, whereas the lower part, lining the hypothalamic 'hypophyseotrophic' area is covered by specialized bipolar cells, the tanycytes, presenting numerous microvilli, few isolated cilia and apical bulbous protrusions. Their distal process is in contact with the basal membrane of the portal vessels. A possible absorption-transport function has been attributed to these cells and is discussed in the light of the findings and the literature data.
