Astrocytes

Astrocyte, a star-shaped cell that is a type of neuroglia found in the nervous system in invertebrates and vertebrates. Astrocytes can be subdivided into fibrous and protoplasmic types. Fibrous astrocytes are widespread among myelinated nerve fibers in the white matter of the central nervous system. The organelles observed in the somates of neurons are also observed in the astrocytes, but they seem much more sparse. These cells are characterized by the presence of numerous fibrils in their cytoplasm. The main processes exit the cell in a radial direction (hence the name astrocyte, which means "star-shaped cell"), forming expansions and end feet at the surface of the vascular capillaries.
