1.Glioma is the most common type of primary intracranial tumors in human. It developed from astrocytoma, oligodendroglioma, ependymoma, which were induced by neural ectoblast.

腦膠質瘤是由神經(jīng)外胚葉衍化而來的膠質細胞即星形膠質細胞、少枝膠質細胞和室管膜膠質細胞等發(fā)生的腫瘤，是顱內最常見的惡性腫瘤。

它由星形細胞瘤，少突膠質細胞瘤，室管膜瘤發(fā)展而來，它們是由神經(jīng)外胚層細胞誘導的。
