Astrocytes

...  are the neuroglial cells of the central nervous system. They are the supporting structures for the main cell of the tissue, the neurons. It derived its name from its star-shaped appearance. The big cell body with its branching processes provides the characteristic appearance of the cell. When viewed under the microscope, you can easily distinguish them by their shape. Physiologically,  ...

Axon

...  the cell. Types of neuroglia These neuroglial cells have a variety of functions based on their types. Schwann cells or neurolemma cells, as previously mentioned, are important insulating layers. The astrocytes provide the vital support tissue of the central nervous system. The ependymal cells are found in the cavities of the central nervous system, while the oligodendrocytes contain many  ...

...  fluid. The endothelial cells in tight junction create the boundary between the two fluids. They are responsible in restricting the flow of substances in the area. The projections of the astrocytes, called the astrocytic feet or the glia limitans, surround the endothelial cells, providing the much needed support. Discovery Paul Ehrlich is the person responsible for the discovery of  ...

Neurolgia

...  is obtained from one of the primary cell layers responsible for creating the neurons- the ectoderm. It has six categories: oligodendrocytes, neurolemmocytes, microglia, ependymal, astrocytes and ganglionic gliocytes. Take a look at the characteristics of each. Neurolemmocytes - It makes up the myelin layers, the ones surrounding the axon cells in the peripheral nervous system.  ...
