Answer:
B. Information processing
Step-by-step explanation:
Glia, also known as glial cells or neuroglia, are non-neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system. They maintain homeostasis, form myelin, and provide support and protection for neurons.
The predominant neuroglia in the brain are astrocytes. These cells are multipolar and provide structural, metabolic and phagocytic support to neurons. They line cavities of brain and spinal cord and maintain cerebrospinal fluid (CSF) flow.
