The cerebellum is a region of the brain that plays an important role in the integration of sensory perception, coordination and motor control.
Mnemonic: Ce<(r)ebel>l(um). I broke the word down into two words: rebel and rum. I then created a rhyme.
There was a rebellious pirate who drank too much rum /
he tried to walk on the edge of the ship, lost coordination and fell on his bum.
