What distinguishes autoregulation in cerebral blood vessels from autoregulation in systemic vessels under changing blood pressure?

A)Greater reliance on myogenic response
B)Reduced sensitivity to carbon dioxide
C)Exaggerated response to sympathetic stimulation
D)Increased sensitivity to metabolic factors

💡 Explanation

Cerebral vessels are highly sensitive to local metabolic demands to maintain constant cerebral blood flow. Because the brain needs continuous oxygen and glucose supply, autoregulation is strongly influenced by metabolic factors such as pH and adenosine. Therefore, cerebral vessels react more intensely to these signals rather than to systemic signals alone.
