Explanation Arterial anastomoses are formed by the combination of different arteries. The four paired arteries that supply blood to the head and neck are the common carotid arteries and three branches from each subclavian artery; vertebral arteries; thyrocervical trunks and the costocervical trunks. The vertebral arteries originate from the subclavian arteries at the root of the neck and ascend through the transverse processes of cervical vertebrae. These arteries then enter the skull through the foramen magnum. The right and left vertebral arteries unite to form the basilar artery, which further branches at the pons-midbrain border to form a pair of posterior cerebral arteries...

Summary Introduction

To review:

Name of the arterial anastomosis at the base of the cerebrum.

Introduction:

The part of a circulatory system that carries the blood from the heart to different parts of the body (except lungs) and then returns to the heart is called a systemic circuit. Arteries, veins, and capillaries are the major blood vessels carrying blood. Arteries carry blood away from the heart, whereas veins carry blood towards the heart.
