  • Astrocytes can be separated into protoplasmic and fibrous kinds. In the central nervous system's white matter, myelinated nerve fibers are frequently surrounded by fibrous astrocytes.
  • Numerous cytoplasmic processes on astrocytes end on axons, neuronal cell bodies, blood vessels, and synaptic terminals.

c) Astrocytes support neurons physically and metabolically.

d) Astrocytes help in transfer of blood-borne materials to the neuron, and injury response of the brain and repair of brain injuries.
