← Human Body & HealthFollowing a traumatic brain injury causing diffuse axonal injury, why does impaired axonal transport exacerbate the metabolic crisis despite initial stabilization?
A)Astrocytes rapidly clear excess glutamate
B)Microglia immediately restore ion homeostasis
C)Oligodendrocytes promptly remyelinate damaged axons
D)Energy delivery to repair is limited✓
💡 Explanation
Impaired axonal transport hinders the delivery of mitochondria and necessary repair proteins to the damaged axon segments, because this transport is crucial for supplying energy and building blocks. Therefore, the metabolic crisis is exacerbated, rather than resolved, because essential cellular processes are energy-starved and cannot be sustained, rather than glial cells compensating for these deficits.
