Transmitters Such as Glutamate Can Be Released by Dying Nerve

Transmitters such as glutamate can be released by dying nerve cells in the brain due to injury, which depolarizes nearby glial cells. One consequence of this is glial cells

A) also release glutamate, exacerbating the effect of brain injury.
B) release calcium, exacerbating the effect of the brain injury.
C) release debris, increasing immune response in the brain.
D) fire action potentials, causing deleterious signaling through the brain region.
E) die, increasing the volume of the extracellular space.
