Many common brain disorders, including stroke, may result in damage due to the release of the amino acid glutamate by
A) astrocytes.
B) oligodendrocytes.
C) Schwann cells.
D) microglia.

Question

Quizplus · Accepted Answer

Glutamate is primarily released by astrocytes, which are a type of glial cell in the brain. When brain damage occurs, such as in a stroke, astrocytes may release excessive amounts of glutamate, leading to further damage and cell death. Glutamate is an excitatory neurotransmitter that can overstimulate neurons, leading to a number of neurological symptoms.
