After ischemia, neurons deprived of blood:
A) transform from neurons into glia.
B) lose much of their oxygen and glucose supplies.
C) break down the blood-brain barrier.
D) increase the velocity of their action potentials.

Question

Quizplus · Accepted Answer

Ischemia is a condition in which blood supply to an organ is restricted or completely cut off. The brain is particularly sensitive to ischemic injury because it requires a constant supply of oxygen and glucose to function. When blood supply to neurons is interrupted, they lose much of their oxygen and glucose supplies, which can lead to cellular damage or death. Neurons will not transform into glia or break down the blood-brain barrier, and ischemic injury is not known to increase the velocity of action potentials.
