Parts of the brain where metabolic activity is relatively high are characterized by
A)elevated regional blood flow.
B)increased cerebrospinal fluid production.
C)a high degree of myelination.
D)greater concentrations of calcium ions.

Question

Quizplus · Accepted Answer

Elevated regional blood flow is the best choice, as increased metabolic activity in the brain requires more oxygen and nutrients, which are delivered through increased blood flow to the area.

The other options (B, C, D) are not directly related to metabolic activity in the brain. Increased cerebrospinal fluid production and greater concentrations of calcium ions may be associated with certain brain functions or conditions, but they are not general indicators of metabolic activity. Myelination is important for neural communication, but it is not directly related to metabolic activity either.
