Keith_Richards [23]

Astrocytes perform the function of all of the given options i.e., induce the formation of the blood-brain barrier, physically support neurons, are important in the repair of brain injuries and in neural formation, take up excess K from the brain ECF.

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.
