Final answer:
Glial cells such as astrocytes, oligodendrocytes, microglia, and ependymal cells each hold potential for treatments in neural degenerative disorders due to their integral roles in the maintenance, protection, and functioning of the nervous system.
Step-by-step explanation:
Glial cells play crucial roles within the nervous system, both in the central nervous system (CNS) and the peripheral nervous system (PNS). Some of these cells, like astrocytes and oligodendrocytes, are integral to the maintenance and functioning of neural networks. Astrocytes help maintain the chemical environment around neurons and are key in sustaining the blood-brain barrier. Oligodendrocytes, on the other hand, are responsible for the myelination of neurons within the CNS. Microglia serve as the immune defense within the CNS, where they act as phagocytes. Finally, ependymal cells play a part in producing cerebrospinal fluid that cushions neurons. Each type of glial cell contributes to the overall health of the nervous system and therefore holds potential for treatments in neural degenerative disorders.
