. The vertebral arteries have many small branches. A fetal origin of the posterior cerebral artery is a common variant in the posterior cerebral circulation estimated to occur in 20-30 of individuals 2. The posterior communicating artery PCom is larger than the P1 segment of the posterior cerebral artery PCA and supplies the bulk of the blood to the PCA.
Its crucial purpose is to serve the cerebellum brainstem thalamus occipital and medial temporal lobes of the brain with oxygen-rich blood. It serves as the main blood supply to the back of the brain where the occipital lobes cerebellum and brainstem are located. By TeachMeSeries Ltd 2022 Fig 12 The right vertebral artery.
With an average diameter of 3 to 4 millimeters. An artery that supplies blood to the medial side of the cerebral hemisphere and the corpus callosum. The basilar artery is located at the base of the brain where the two vertebral arteries come together.

If bilateral the basilar artery is significantly smaller than normal. They carry blood to the brain and spinal cord which are part of the nervous system. The vertebral arteries are part of the circulatory system.
The vertebral arteries join the basilar artery to form the vertebrobasilar system which supplies blood to the posterior portion of the circle of Willis. Anterior choroidal artery supplies structures in the brain important for motor control and vision. The internal carotids then continue as the middle cerebral artery which supplies the lateral portions of the cerebrum.
Symptoms of a stroke vary and may. The anterior cerebral artery anastomoses with the contralateral anterior cerebral artery via the anterior communicating artery. It is part of the circle of Willis and it branches from the internal carotid artery at the base of the brain.
The anterior cerebral artery ACA is one of a pair of cerebral arteries that supplies oxygenated blood to most midline portions of the frontal lobes and superior medial parietal lobes of the brainThe two anterior cerebral arteries arise from the internal carotid artery and are part of the circle of WillisThe left and right anterior cerebral arteries are connected by the anterior.
