Prin metode histologice şi ultramicroscopice au fost studiate structura, vascularizarea şi aparatul nervos al plexurilor coroide din ventriculele trei şi patru ale creierului uman. S-au stabilit particularităţi structurale ale vascularizaţiei şi ale aparatului nervos, care este format din fi bre nervoase, fi lete şi plexuri nervoase, terminaţiuni nervoase bine evidenţiate. Aspectul macromicroscopic al plexurilor coroide se afl ă în raport direct cu perioadele ontogenetice de dezvoltare.

The structure, microcirculatory net and nervous system of choroids plexuses of the three of the four ventricles of human brain have been studied by histologic, and ultramicroscopical methods. According to investigations the tissular structural particularities of vascular net and choroids plexus innervations with the myeline and amyeline nervous fi bres, fascicles and nervous plexuses and nervous endings have been established. The structure and development of choroids plexuses of the three of the four ventricles of the human brain is in correlation with the respective stage of ontogenesis.
