Abstract

The end feet (Fig. A1) of the astrocytes contact one another by means of a nexus (Fig. A2) and form the membrana limitans gliae superficialis. The glial processes are separated from the pia mater (Fig. A3) and its collagen microfibrils (Fig. A4), fibrocytic processes (Fig. A5), and blood capillaries (Fig. A6) by a basal lamina (Fig. A7). Beneath the surface glial membrane are located numerous processes (Fig. A8) of nerve and glia cells belonging to the neuropil.
