Cerebral circulation - Wikipedia
Blood supply to the brain is normally divided into anterior and posterior segments, relating to the different arteries that supply the brain. The two main pairs of arteries are the internal carotid arteries (supply the anterior brain) and vertebral arteries …
Arterial Supply of the Brain | Circle of Willis | Geeky Medics
2018年9月9日 · The arterial blood supply to the brain can be divided into the anterior and posterior circulation. The former is derived from the left and right internal carotid arteries , and the latter is derived from the left and right vertebral arteries .

2023年7月24日 · The blood supply to the brain divides into an anterior and posterior circulation. The anterior circulation derives blood from the bilateral internal carotid arteries (ICA) and supplies blood to the majority of the cerebral hemispheres, including the frontal lobes, parietal lobes, lateral temporal lobes and anterior part of deep cerebral ...
Blood supply to the brain: Anatomy of cerebral arteries - Kenhub
2023年10月30日 · The derivatives of the internal carotid arteries form the anterior blood supply (anterior circulation) of the brain, which includes the anterior and middle cerebral arteries. The subclavian artery is divided into three parts based on anatomical landmarks.

2023年7月24日 · Four principal arteries supply the brain, namely one internal carotid artery (ICA) and one vertebral artery on each side. Classically the internal carotid arteries on both sides are referred to as the anterior circulation, while the vertebral-basilar arterial system composes the posterior circulation. [1] .
Anterior and Posterior Circulation of the Brain
The Circle of Willis is fed by the anterior circulation, coming from the carotid arteries which rise through the ventral neck; and the posterior circulation, which runs through the vertebral arteries. The vertebral arteries anastomose at the medulla to form the basilar artery.

2022年10月17日 · Before joining to form the basilar artery, they give off the posterior inferior cerebellar arteries and the anterior spinal arteries. Following the joining, the basilar artery gives off the paramedian pontine arteries, labyrinthine arteries, the long circumferential anterior inferior cerebellar arteries, and superior cerebellar arteries.
Circle of Willis: Anatomy and function - Kenhub
2023年10月30日 · The main function of the circle of Willis is to provide a collateral blood flow between the anterior and posterior arterial systems of the brain. Additionally, it offers the alternate blood flow pathways between the right and left cerebral hemispheres .
Cerebral circulation 1: anatomy - BJA Education
Eighty-five percent of berry aneurysms are located in the anterior circulation. The three most common areas are the anterior communicating artery (30%), followed by the posterior communicating artery (25%) and the MCA (20%). 7
The cerebral circulation and cerebrovascular disease I: Anatomy
Beginning with its origin in the branches of the aorta, we start by describing the arterial system. This system is partitioned into two major divisions (anterior and posterior circulations) that differ significantly in features and pathogenic potential. The systems, and the major branches that comprise them, are described.
