Left medial branch of superior cerebellar artery (Ramus medialis arteriae superioris cerebelli)
Educational content only — not medical advice.
Anatomy
An arterial branch arising from the superior cerebellar artery (SCA) that runs over the superior medullary velum and superior vermis to form collateral anastomoses with the contralateral artery. It coordinates cerebellar motor integration and balance control.
Clinical notes
Neurovascular conflict between the superior cerebellar artery and the root entry zone of the trigeminal nerve (CN V) causes trigeminal neuralgia, cured by microvascular decompression (Jannetta procedure).
