Final answer:
Astrocytes are responsible for neural repair in the CNS, aiding in recovery after injury.
Step-by-step explanation:
The glial cell responsible for neural repair is the astrocyte.
Astrocytes play a crucial role in the central nervous system (CNS) by providing structural and metabolic support to neurons. They help in repairing and scarring processes after neural injury, maintaining the blood-brain barrier, and regulating ion concentrations in the interstitial space. While other glial cells like oligodendrocytes, microglia, and ependymal cells have functions such as myelin sheath formation, immune surveillance, and cerebrospinal fluid production respectively, it is the astrocytes that are primarily associated with neural repair post-injury.
Microglia also contribute to repair and regeneration, primarily through scavenging damaged cells and pathogens, but astrocytes have a more direct role in the restoration of neural tissues.
