What is the function of astrocytes in the brain? a) Formation of myelin around axons. b) Cleaning cellular debris from lesions or infections. c) ...

The correct answer is b), astrocytes are responsible for cleaning cellular debris from lesions or infections.

Astrocytes are glial cells in the brain that play a variety of roles, including:

• Supporting neurons: Astrocytes provide structural support for neurons and help to maintain the extracellular environment around neurons.
• Clearing debris: Astrocytes help to clear cellular debris from the brain, including debris from lesions or infections.
• Inducing the formation of the blood-brain barrier: Astrocytes play a role in the formation of the blood-brain barrier, which is a barrier that prevents harmful substances from entering the brain from the bloodstream.
• Synaptic transmission: Astrocytes may also play a role in synaptic transmission, the process by which neurons communicate with each other.

Astrocytes are essential for the proper functioning of the brain and they play a role in a variety of important processes.
