- Both invertebrates and vertebrates have Astrocytes, a star-shaped cell kind of neuroglia, in their nervous systems.
- 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.
b) The development of the blood-brain barrier is aided by the Astrocytes
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.
e) They also help with detoxification, migratory guidance, energy metabolism regulation and removal of excess K from brain ECF.
