The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including humans. [1] It is named after Thomas Willis (1621–1675), an English physician. [2]
Willis was a pioneer in research into the anatomy of the brain, nervous system and muscles. His most notable discovery was the "Circle of Willis", a circle of arteries on the base of the brain. Willis's anatomy of the brain and nerves, as described in his Cerebri anatome of 1664, is minute and elaborate.
There are many examples of normal arterio-arterial anastomoses in the body. Clinically important examples include: Circle of Willis (in the brain) Coronary: anterior interventricular artery and posterior interventricular artery of the heart; Scapular anastomosis (for the subclavian vessels)

The earliest known inhabitants of Sayville were the Secatogue tribe of the Algonquian peoples. Sayville was founded by John Edwards (b. 1738) of East Hampton, New York. He built his home, the first in Sayville, in 1761, located at what is now the northwest corner of Foster Avenue and Edwards Street. The house was destroyed by fire in March 1913.
