circle of Willis. Etymology: Thomas Willis, English physician, 1621-1675. a vascular network at the base of the brain formed by the interconnection of the middle cerebral, anterior cerebral, posterior cerebral, basilar, anterior communicating, and posterior communicating arteries.
When all arteries are functioning normally, their blood supplies will not mix where they meet in the Circle because the pressure of their streams will be equal. As long as the Circle of Willis can maintain blood pressure at fifty percent of its normal level, no infarction or death of tissue will occur in an area where a blockage exists.
