What artery supplies superior cerebellum?
The superior cerebellar artery (SCA) arises from the distal basilar artery, just below the posterior cerebral artery (PCA) and typically supplies: whole superior surface of the cerebellar hemispheres down to the great horizontal fissure. superior vermis. dentate nucleus.
What are the three arteries of the cerebellum?
The arterial vascularization of the cerebellum is based on three arteries which all originate from the vertebrobasilar system: the superior cerebellar artery (SCA), the anterior and inferior cerebellar artery (AICA), and the posterior and inferior cerebellar artery (PICA).

What is the blood supply of brainstem?
The blood supply of the brainstem and cerebellum is derived entirely from branches of the vertebrobasilar circulation. The vertebral arteries enter the cranium via the foramen magnum and course superiorly along the ventrolateral surface of medulla.
Which artery supplies blood to the pons and the cerebellum?
Among the most important dorsal-lateral arteries (also called long circumferential arteries) are the posterior inferior cerebellar artery (PICA) and the anterior inferior cerebellar artery (AICA), which supply distinct regions of the medulla and pons.
What blood vessels supply blood to the heart?
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. The coronary arteries wrap around the outside of the heart.
What drains the cerebellum?
Cerebellar veins are veins which drain the cerebellum. They consist of the superior cerebellar veins and the inferior cerebellar veins.
What artery supplies anterior lobe of cerebellum?
Central Arterial Supply The AICA arises from the basilar artery and supplies the cerebellopontine angle, part of the anterior cerebellum, part of the vermis and the vestibulocerebellum, part of the rostral pons, the middle cerebellar peduncle, and cranial nerves VII (facial nerve) and VIII.
Is venous drainage blood supply?
Systemic veins: Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.
