Functions of astrocytes include all of the following except

Neporo4naja [7]

The question is incomplete. The complete question is as follows:

Functions of astrocytes include all of the following, except

A) performing repairs in damaged neural tissue.

B) guiding neuron development.

C) functioning in action potential transmission.

D) maintaining the blood-brain barrier.

E) creating a three-dimensional framework for the CNS.

Answer:

Functioning in action potential transmission.

Explanation:

Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.

Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.

Thus, the correct answer is option (c).
