神经胶质主要包括脑和脊髓内的星状细胞、少突细胞,小胶质细胞和周围神经节内的卫星细胞,有人认为还应包括脑室坒上的室管膜细胞。在鸟的脊髓腰段背侧部有一种富含糖元的细胞,称为糖元体(Glycogen body),据说这也是一种星状细胞。单孔目动物的胶质细胞只有一种,尚未分化为星状及少突细胞,大约这种未分化的胶质细胞兼有后两种细胞的功能。近日对神经胶质又有一些研究,今记述其研究结果如下:1.神经胶质的发生:据 Sturrok 用电镜于小鼠前连合前肢所作的研究,神经胶质的组织
Neuroglia mainly include astrocytes, oligodendrocytes, microglia and satellite cells in the peripheral ganglia in the brain and spinal cord. Some people think that it should also include ependymal cells in the suprachoroidal space. In the dorsal part of the spinal cord, the bird has a glycogen-rich cell called the Glycogen body, which is said to be a stellate cell. There is only one type of glial cells in the order of uniformed animals, which have not yet differentiated into stellate and oligodendrocyte cells. About this undifferentiated glial cell combines the functions of the latter two cells. There are some recent studies on glia, the results described below are as follows: 1. Glial occurrence: According to Sturrok electron microscopy in mice prefrontal commissure research, glial organization
