Final answer:
Neural, endocrine, and autoregulatory mechanisms affect cerebral blood flow, with neural mechanisms including cardiovascular centers and chemoreceptors. Autoregulation is the local control of vasodilation and constriction in response to chemical signals and myogenic response.
Step-by-step explanation:
The determinant of cerebral blood flow is one of the variables affecting arterial blood flow and blood pressure. Cerebral blood flow is regulated by neural, endocrine, and autoregulatory mechanisms. Neural mechanisms include the cardiovascular centers in the medulla oblongata, baroreceptors in the aorta and carotid arteries, and chemoreceptors that monitor blood levels of oxygen, carbon dioxide, and hydrogen ions. Autoregulation is the local control of vasodilation and constriction by chemical signals and the myogenic response.
