The pontine artery is made up of tiny blood vessels that are part of the posterior cerebral circulation system. The pontine arteries are responsible for helping the body pump oxygen-rich blood from the heart to the brain. These pontine arteries are located on both sides of the basilar artery. The basilar artery is the central artery that supplies oxygen-rich blood to the middle section of the brain. The pontine arteries branch off at right angles from the basilar artery. Each branch of the pontine arteries contains three to five single arteries. There is a right branch and a left branch; both branches are used to supply blood to both sides of the brain equally. A single pontine artery carries the oxygen-filled blood to the pons, a section located in the middle of the brain. The pontine arteries are also responsible for supplying the oxygen-rich blood to the other parts of the brain that are located directly next to the pons section.
