The document summarizes the major arteries that supply the brain and spinal cord, including the anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), posterior inferior cerebellar artery (PICA), anterior spinal artery, and posterior spinal artery. It details the origin, course, and territory supplied by each artery.

1. End arteries supplying the brain and spinal cord C. Riedinger
Artery Origin Course Territory
* above optic nerve
* follows curvature of corpus
* medial aspect of hemispheres
callosum
Anterior cerebral (ACA) internal carotid * sensory amd cortical areas of lower limb
* along longitudinal fissure
* "mohican"
* back to parieto-occipital sulcus
* cortical territory: sensory and motor cortex
* largest * auditory cortex
Middle cerebral (MCA) internal carotid * moving out laterally * insula
* lateral and inferior hemispheres * internal capsule
* basal ganglia
* posteriorly
* curves around midbrain * occipital lobe
Posterior cerebral (PCA) internal carotid
* inferomedial aspect of temporal * visual cortex
lobe
* from junction of pons and * superior surface beneath tentorium cerebelli
Superior cerebellar (SCA) basilar artery
midbrain, where basilar artery ends * midbrain
* originates close to junction of * anterior aspect of inferior surface of cerebellum
Anterior inferior cerebellar
basilar artery medulla at pons, where basilar * pons
(AICA)
artery begins * medulla
Posterior inferior cerebellar * posterior aspect of inferior surface of cerebellum
vertebral artery * near olive
(PICA) * lateral part of medulla
Anterior spinal
vertebral artery * descends down spinal cord * medulla and spinal cord
Posterior spinal
