  2. Circle of Willis - Wikipedia

    en.wikipedia.org/wiki/Circle_of_Willis

    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]

  5. Circulatory anastomosis - Wikipedia

    en.wikipedia.org/wiki/Circulatory_anastomosis

    Circle of Willis (in the brain) Coronary: anterior interventricular artery and posterior interventricular artery of the heart; Scapular anastomosis (for the subclavian vessels) Joint anastomoses: Almost all joints receive anastomotic blood supply from more than one source. Shoulder (and circumflex humeral) Elbow (see blood supply of elbow)

  6. Vertebral artery - Wikipedia

    en.wikipedia.org/wiki/Vertebral_artery

    The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of the brain if there is compromise to one of the carotids. At each cervical level, the vertebral artery sends branches to the surrounding musculature via the anterior spinal arteries.

  7. Cerebral arteries - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteries

    Arteries of head and neck. Angiogram of the arterial supply.. The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain.

  8. Artery - Wikipedia

    en.wikipedia.org/wiki/Artery

    The aorta is the largest blood vessel in human body. The aorta is the root systemic artery (i.e., main artery). In humans, it receives blood directly from the left ventricle of the heart via the aortic valve. As the aorta branches and these arteries branch, in turn, they become successively smaller in diameter, down to the arterioles.

  9. Anastomosis - Wikipedia

    en.wikipedia.org/wiki/Anastomosis

    In circulatory anastomoses, many arteries naturally anastomose with each other; for example, the inferior epigastric artery and superior epigastric artery, or the anterior and/or posterior communicating arteries in the Circle of Willis in the brain. The circulatory anastomosis is further divided into arterial and venous anastomosis.
