Question

Quizplus · Accepted Answer

The central nervous system ischemic response refers to the body's response to a lack of oxygen to the brain, which can occur during emergency conditions such as shock or cardiac arrest. This response plays an important role in controlling blood pressure by increasing sympathetic nervous system activity and vasoconstriction. The other choices are incorrect as there is no increase in blood flow to the vasomotor center, rise in oxygen, or inhibition by a rise in hydrogen ions associated with the ischemic response. Additionally, the role of this response is important under emergency, not normal, conditions.
