Editing Cerebellum (section)

===Blood supply===
The cerebellum is provided with blood from three paired major arteries: the [[superior cerebellar artery]] (SCA), the [[anterior inferior cerebellar artery]] (AICA), and the [[posterior inferior cerebellar artery]] (PICA). The SCA supplies the upper region of the cerebellum. It divides at the upper surface and branches into the pia mater where the branches [[anastomose]] with those of the anterior and posterior inferior cerebellar arteries. The AICA supplies the front part of the undersurface of the cerebellum. The PICA arrives at the undersurface, where it divides into a medial branch and a lateral branch. The medial branch continues backward to the cerebellar notch between the two hemispheres of the cerebellum; while the lateral branch supplies the under surface of the cerebellum, as far as its lateral border, where it anastomoses with the AICA and the SCA.
