Final answer:
The myogenic regulation in the brain helps keep cerebral blood flow constant despite changes in systemic blood pressure.
Step-by-step explanation:
The statement 'Myogenic regulation in the brain helps keep cerebral blood flow constant despite changes in systemic blood pressure' is true.
The myogenic response is a regulatory mechanism that occurs in the walls of arterioles in the brain. When there are changes in systemic blood pressure, the smooth muscle in the walls of arterioles can constrict or dilate to maintain a constant cerebral blood flow. This helps ensure that the brain receives a steady supply of blood regardless of changes in systemic blood pressure.
